The first identification of a sex pheromone of a pine sawfly (Hymenoptera, Diprionidae) dates back almost thirty years. Since then, female-produced pheromones of over twenty diprionid species have been investigated by solvent extraction followed by separation and identification. However, no study has shown what the females actually release. Collection of airborne compounds using absorbtion on charcoal filter as well as solid phase microextraction (SPME) followed by analysis employing gas chromatography combined with mass spectrometry (GC-MS), revealed an unusual system in Diprion pini, in which the pheromone precursor alcohol, 3,7-dimethyl-2-tridecanol, is released together with acetic, propionic, butyric and isobutyric acids. The corresponding acetate, propionate and butyrate esters of 3,7-dimethyl-2-tridecanol were also found in the samples. All esters were electrophysiologically active, and the propionate and isobutyrate were attractive in trapping experiments. Based on these and earlier ...

Most sawflies (Symphyta) are plant feeders and many species are pest insects in agriculture or forestry. Every year the larvae of diprionids (conifer or pine sawflies) defoliate large areas of conifer forests in Europe, Asia and North America. The most important effect of pine sawfly defoliation is reduced growth of the trees. In some areas chemical insecticides are used to reduce populations and damage. The general biology and distribution of these species are usually well known, whereas the chemical ecology of sawflies is less known, with exception of the family Diprionidae.. Within this project we attempt to characterize pheromones of different sawfly species, and so far emphasis has been on diprionid species. We also investigate the possibility to use pheromones for monitoring and control of sawflies. Until now the following diprionid species have been studied within the project: Diprion jingyuanensis, D. pini, D. similis, Gilpinia frutetorum, G. pallida, G. socia, Macrodiprion nemoralis, ...

The taxonomy of the ichneumonids is still poorly known. The family is highly diverse, containing 24,000 described species. Approximately 60,000 species are estimated to exist worldwide, though some estimates place this number at over 100,000. They are severely undersampled, and studies of their diversity typically produce very high numbers of species which are represented by only a single individual.[19][20] Due to the high diversity, the existence of numerous small and hard to identify species, and the majority of species being undiscovered, it has proven difficult to resolve the phylogeny of the ichneumonids. Even the relationships between subfamilies are unclear. The sheer diversity also means DNA sequence data is only available for a tiny fraction of the species, and detailed cladistic studies require major computing capacity. Extensive catalogues of the ichneumonids include those by Aubert,[9][10][11] Gauld,[21] Perkins,[12][13] and Townes.[14][22][23][24][25] Due to the taxonomic ...
The fall armyworm, Spodoptera frugiperda, a moth originating from tropical and subtropical America, has recently become a serious pest of cereals in sub-Saharan Africa. Biological control offers an economically and environmentally safer alternative to synthetic insecticides that are being used for the management of this pest. Consequently, various biological control options are being considered, including the introduction of Telenomus remus, the main egg parasitoid of S. frugiperda in the Americas, where it is already used in augmentative biological control programmes. During surveys in South, West, and East Africa, parasitized egg masses of S. frugiperda were collected, and the emerged parasitoids were identified through morphological observations and molecular analyses as T. remus. The presence of T. remus in Africa in at least five countries provides a great opportunity to develop augmentative biological control methods and register the parasitoid against S. frugiperda. Surveys should be carried out
Karyotypes of eleven parasitoid species of the family Eulophidae were examined, namely, Chrysocharis laomedon (Walker, 1839) (2n = 10), Chrysocharis sp. aff. laomedon (n = 5, 2n = 10), Chrysocharis sp. aff. albipes (Ashmead, 1904) (2n = 12), Mischotetrastichus petiolatus (Erdös, 1961) (n = 6, 2n = 12), Minotetrastichus frontalis (Nees, 1834) (n = 5, 2n = 10), Cirrospilus pictus (Nees, 1834) (2n = 12), Hyssopus geniculatus (Hartig, 1838) (2n = 16), Sympiesis gordius (Walker, 1839) (2n = 12), S. sericeicornis (Nees, 1834) (2n = 12), Pnigalio agraules (Walker, 1839) (2n = 12 + 0-2B) and Pnigalio gyamiensis Myartseva & Kurashev, 1990 (2n = 12 + 0-6B) reared from Phyllonorycter acerifoliella (Zeller, 1839), Ph. apparella (Herrich-Schäffer, 1855), Ph. issikii (Kumata, 1963) (Gracillariidae) and Chrysoesthia sexguttella (Thunberg, 1794) (Gelechiidae).

Alien parasitic wasps, including accidental introductions and purposefully released biological control agents, have been implicated in the decline of native Hawaiian Lepidoptera. Understanding the potential impacts of alien wasps requires knowledge of ecological parameters that influence parasitism rates for species in their new environment. Sophora seed-feeding Cydia spp. (Lepidoptera: Tortricidae) were surveyed for larval parasitoids to determine how native and alien wasps are partitioned over an elevation gradient (2200-2800 m) on Hawaii Island, Hawaii. Parasitism rate of native Euderus metallicus (Eulophidae) increased with increased elevation, while parasitism rate by immigrant Calliephialtes grapholithae (Ichneumonidae) decreased. Parasitism by Pristomerus hawaiiensis (Ichneumonidae), origins uncertain, also decreased with increased elevation. Two other species, Diadegma blackburni (Ichneumonidae), origins uncertain, and Brasema cushmani (Eupelmidae), a purposefully introduced biological control

Field and laboratory studies were conducted to determine how Apanteles scutellaris and Agathis gibbosa (Hymenoptera: Braconidae) coexist as solitary endophagous parasitoids of potato tuberworm (PTW) larvae, Phthorimaea opercullela (Lepidoptera: Gelechiidae), in southern California. The competitive characteristics of Orgilus jennieae (Hymenoptera: Braconidae), an exotic parasitoid of PTW larvae, were compared with those of the native species to determine its potential for establishment. Emergence of the egg-larval parasitoid Chelonus phthorimaeae (Hymenoptera: Braconidae) from field-collected PTW larvae was compared with those of the other parasitoids, but its competitive interactions were not considered. Seasonal density changes, mine characteristics, and within-plant distributions of PTW larvae were studied to determine their possible impacts on parasitoid interactions. Apanteles scutellaris and A. gibbosa oviposited in similar
Chewing large holes, or entire leaf blades is another, less-common sawfly. The larvae of Megaxyela major (Cresson) is yellow in color with prominent black spots and a black head capsule. Larvae grow to 3/4 inch long before dropping to the ground and pupating. This sawfly has the curious habit of curling around a leafs rachis or midrib during daylight hours (photo at right). As night falls, the larvae continue to feed on entire leaves often leaving just the midrib. We have never had a serious outbreak of this sawfly species ...
Use Trichogramma spp., a moth egg parasite that prevents caterpillars from emerging by laying their eggs in the moth eggs, killing them. Timing the release is important - if you release too early there arent enough pest eggs for the wasps to parasitize - too late means that the pest eggs have hatched and you have a new problem - caterpillar pests. Biology & Life Cycle: Trichogramma wasps lay their eggs inside the pest eggs, stopping development. The larvae feed on the egg and then emerge as adults. The larvae take 10 days to develop within the pest moth egg, which turns brown or black as the larvae pupate. The adult wasps live anywhere from 7 to 14 days, depending on temperature and moisture and the female Trichogramma will parasitize up to 300 pest moth eggs. Eggs on cards usually hatch within 2-5 days. Preferred food: Trichogramma parasitize the eggs of more than 200 pests, including borers, webworms, loopers, leafworms, fruitworms, cutworms, bollworms, and armyworms (except beet armyworms).
VIT is globally accepted as the treatment of choice in venom allergy.15. Although 44 patients in the current study declared a negative effect of VIT on work, caused by changing working time and economic loss due to VIT, most of our participants declared an indifferent effect of VIT on work. Individuals at high risk of sting reported a positive VIT impact on work. This will support the accepted medical approach that occupation may influence the decision to initiate VIT, also for non-life-threatening reactions.5. Another predictor of a perceived positive effect from VIT was completion of treatment. Participants who have already completed VIT are probably more aware of the long-term beneficial effects of treatment. They are less likely to report any drawbacks of VIT, such as the time spent in therapy, which can affect work and social life. A relevant number of participants reported a negative impact of VIT on work and even if we could not find any peculiar characteristic of this group, this finding ...

The HYMENOPTERA class of insects are the only stinging insects. However only a few of the hymenoptera (honeybees, wasps, hornets, yellow jackets and fire ants) cause serious allergic reactions. Overall, the yellow jacket is the most common offender followed by honey bees, wasp and then hornets. Bumblebees rarely sting humans. The base of the stinger of hymenoptera insects is attached to a small venom filled sac. Most stinging insects except the honeybees can reuse their stingers, inflicting multiple venom injections. In contrast, the honeybees stinger is barbed so when it tries to remove its stinger from the skin, both the stinger and venom sacs are torn off and left in the victim. Most hymenoptera actually use their stingers in self defense, for defense of the hive or for killing other insects ...
Figure 3. In general, larvae complete feeding by the time needles emerge from the candelabra. Therefore, those needles are not damaged. There really is only a minor threat of branch or tree death resulting from sawfly larval feeding. However, the loss of second- and third-year needles may be noticeable in landscape trees and ruin their appearance. In late spring, the larvae drop to the ground and pupate in brown, leathery cocoons at the base of trees. Wasp-like adults emerge in fall and lay eggs in the needles before winter. There is one generation per year in Kansas.. Although sawfly larvae look-like caterpillars; they are not caterpillars (Order: Lepidoptera) as they are related to ants, bees, and wasps (Order: Hymenoptera). The best way to tell a sawfly larva from a caterpillar is by the following: 1) sawfly larva have prolegs on every abdominal segment whereas caterpillars are missing prolegs on the abdomen and 2) caterpillar larva have hairs or crochets on their feet whereas sawfly larva do ...

We determined the host range of the parasitoid Trichomalus perfectus (Walker), a candidate for classical biological control of cabbage seedpod weevil, Ceutorhynchus obstrictus (Marsham), an important pest of canola in Canada. Studies were conducted in Europe and in North America. In laboratory experiments, the levels of parasitism (acceptance) of Ceutorhynchus turbatus Schultze, C. cardariae Korotyaev, C. omissusFall and C. querceti (Gyllenhal) by T. perfectus were not significantly different than of the target host C. obstrictus. Although C. typhae (Herbst), C. pallidactylus (Marsham), C. americanus Buchanan, C. neglectusBlatchely and Ceutorhynchus sp. nr. nodipennis were parasitised by T. perfectus, the levels of parasitism were significantly lower on these species than on C. obstrictus.

Hummingbirds are very small birds with high metabolisms. They must feed almost constantly since most of their energy is spent flying. Campylopterus hemileucurus is primarily nectivorous but also insectivorous. Most of their diet comes from floral nectar, with the rest from arthropods (Phylum Arthropoda), including flies (Order Diptera), spiders (Order Araneae), ants (Order Hymenoptera), beetles (Order Coleoptera), and other small organisms. They occasionally feed on non-insect arthropods. Their only limitation in feeding is prey size, although they are capable of swallowing surprisingly large organisms.. Food choice of all hummingbirds is chiefly determined by season and habitat. As a non-migratory hummingbird, C. hemileucurus depends on local food resources. They obtain nectar from brightly colored flowers, particularly those in the Neotropical genus Marcgravia during their flowering season. They are most attracted to red and yellow flowers that are shaped like their beaks (long, tubular, and ...
Working our way across the Dunson Garden, we stopped at a patch of Sensitive Fern, with its large undivided pinnae and winged rachis. It gets its name because it is cold-sensitive. Dale was amazed that many of the fronds had been heavily grazed by insects, some nearly completely consumed. Most ferns have a natural, chemical protection against grazing by herbivores or insects that might eat and damage the leafy parts of the plant. But the website illinoiswildflowers.com clued us in that larvae of the sawfly Hemitaxonus dubitatus do feed on the fronds but, not having seen the culprit today, we dont know if that is the insect responsible for the damage we saw. [That sawfly species is also only known from Michigan and the NE states, but these insects are not well studied and it is possible that it, or a related form, occurs here in Georgia.

P.F. Whitehead. Moor Leys, Little Comberton, Pershore, Worcestershire WR10 3EH Email: [email protected] Reference was recently made (Whitehead, 2013) to the finding of Ancistrocerus oviventris (Wesmael, 1836) at Grafton Wood, Worcestershire on 25 August 2013. I recently reviewed the specimen and decided to send it to Dr Michael Archer for examination; he found that it was a female Gymnomerus laevipes (Shuckard, 1837). This published record of A. oviventris is therefore untenable.. Richards (1980) keys the subfamily Eumeninae and states that the head of Gymnomerus has two approximate occasionally fused pubescent pits and illustrates them as figure 25. In the present example these pits are very small, much smaller than this figure 25 and situated well behind the eyes and might be passed over; this and a subsequent failure to attend to other points of detail lead to the specimen being misidentified. Dr Archer also stated that when considering the identity of certain individuals reliance is ...
Of the parasites which attack blow-flies, Mormoniella vitripennis Walk. is one of the best known and most widely distributed. The stock used in these experiments was derived from host pupae which had been exposed in the laboratory. It had been bred in captivity for about a year when these investigations were started. From time to time, fresh parasites, obtained from field-parasitized pupae, were added.
