Besides, the Wolbachia titers (the copy numbers of wsp ) in T. dendrolimi females without oviposition experience (the control), supplied with host eggs for only 1 h per day and supplied with host eggs all the time were detected by fluorescence quantitative real-time PCR. (insect.org.cn)
The Wolbachia titer in T. dendrolimi females without oviposition experience was significantly higher than that in T. dendrolimi females supplied with host eggs all the time, but showed no significant difference from that in T. dendrolimi females supplied with host eggs for only 1 h per day. (insect.org.cn)
The aim of this study was to determine the courtship behaviour, mating and oviposition of unmated or mated C. noackae females parasitizing T. peregrinus eggs utilizing the same rearing system used in biological control programmes in Brazil. (unesp.br)
Ten unmated or mated females were placed individually in vials with 10 T. peregrinus eggs each, and oviposition behaviour, percentage of eggs inserted and parasitized, viability and sex ratio of emerged C. noackae were recorded. (unesp.br)
The time spent finding the first host, evaluating and inserting the ovipositor was similar for mated and unmated C. noackae females, as well as the frequency of inserted and parasitized eggs and their viability. (unesp.br)
Unlike most vinegar flies that prefer over ripe, damaged or dropped fruit, the SWD female has a serrated ovipositor that allows her to saw through intact fruit and lay her eggs just below the skin. (novascotiacranberryblog.com)
To lay their eggs, cicada stab a needle-like ovipositor into the branch that can cause these tender twigs to break, wither, and die. (osu.edu)

Behaviour3
Marshall (2020) observed a native New Zealand Pollenia displaying what can only be interpreted as oviposition behaviour, extending the ovipositor into a mixture of loose soil and organic debris. (pensoft.net)
Here we linked oviposition behaviour of the specialist willow sawfly Nematus oligospilus F¨orster (Hymenoptera: Tenthredinidae) with leaf traits on different Salix L. (Salicaceae) genotypes. (uchile.cl)
This behaviour is allowed by an enlarged and serrated ovipositor that can pierce intact fruit skin, and by multiple contact sensory systems (mechanosensation and taste) that detect the optimal egg-laying substrates. (fmach.it)
Suzukii4
Here, we tested the hypothesis that bristles present in the D. suzukii ovipositor tip contribute to these sensory modalities. (fmach.it)
Fluorescent labelling in D. suzukii and D. melanogaster revealed that pegs located on the ventral side of the ovipositor tip are innervated by a single neuron in both species. (fmach.it)
RNA-sequencing profiled gene expression, notably sensory receptor genes of the terminalia of D. suzukii and of three other Drosophila species with changes in their ovipositor structure (from serrated to blunt ovipositor: Drosophila subpulchrella, Drosophila biarmipes and D. melanogaster).

Cicada3
Oak tree showing declining branch tips from cicada oviposition. (osu.edu)
In the ichneumon wasp genus Megarhyssa, the females have a slender ovipositor (terebra) several inches long that is used to drill into the wood of tree trunks. (wikipedia.org)
This was done as a first step to find oviposition cues that guide females to their host plants. (uchile.cl)
At oviposition, females bend upward and the tarsi are anchored to the tissue with the spines of the third pair of legs to push the ovipositor into the tough palm tissue. (ict4water.eu)
Adult females of Nasonia vitripennis inject a venomous mixture into its host flies prior to oviposition. (mdpi.com)
Twigs1

Behavior2
The oviposition behavior is almost identical to that of Chrysis shanghaiensis Smith, which attacks cocoons of Lepidoptera (Clausen 1940/62). (ucr.edu)
Parasitoids can be classified according to their oviposition (egg-laying) behavior. (umd.edu)
Wasp1
Fig wasp ovipositors have specialized serrated teeth to penetrate fruits, but gall wasps have either uniform teeth or no teeth on their ovipositors, meaning the morphology of the organ is related to the life history. (wikipedia.org)
Cicadas3
aaa replica bags We hypothesized that cicadas have metals in the cuticle of their ovipositors, increasing individual fitness by strengthening the cuticle Hermes Replica Handbags to improve successful oviposition into hard wood. (kscmfltd.com)
Energy dispersive x ray spectroscopy (EDS) and scanning electron microscopy (SEM) were used to determine the elemental composition of the cuticle of ovipositors Hermes Kelly Replica of periodical and annual cicadas. (kscmfltd.com)
If you have not seen or heard cicadas in your yard and are not finding oviposition scars in declining trees, more investigation may be warranted. (osu.edu)
Glands2
The stingers of the Aculeata (wasps, hornets, bees, and ants) are ovipositors, highly modified and with associated venom glands. (wikipedia.org)
The protective "shell" of protein covering the insect's egg that is secreted before oviposition by accessory glands in the female's reproductive system. (ncsu.edu)

Host2
To host feed, E. formosa wounds nymphs or pupae by probing with the ovipositor for up to six minutes and feeds from wounds which wasps may enlarge with their mandibles. (cornell.edu)
Nymphs that have been used for feeding are not used for oviposition, and previously parasitized whiteflies are not used for host feeding (Hoddle et al. (cornell.edu)
Hosts1
Adults obtain energy and nutrients by consuming honeydew and hemolymph of hosts that are pierced with the ovipositor, but in which no egg is deposited. (cornell.edu)
Survival1
We assume that the difference in ovipositor length and egg number of A . signifer between the two populations may be related to phenotypic plasticity required for oviposition to minimize egg ejection and maximize embryo survival. (bioone.org)
Longer2
The 3-jointed ovipositor is longer than the abdomen when extended. (ucr.edu)
However, the Goesan population had longer ovipositors (mean ± SD, 21.68 ± 2.84 vs . 19.33 ± 1.85) and a higher egg number (22.46 ± 12.31 vs. 17.16 ± 7.23) than the Danyang population. (bioone.org)

Life1
Ovipositor morphology correlates with life history evolution in agaonid fig wasps" (PDF). (wikipedia.org)
Hole2
When one is found, she gnaws a hole in the cocoon wall, and the extensible ovipositor is inserted by a backward thrust. (ucr.edu)
When oviposition is complete, the female smears a quantity of mucilaginous material over the hole in the cocoon wall, thereby sealing it. (ucr.edu)
