  • Although bees are often lauded for their pollination prowess, other insects are just as important for the success of the world's crops, according to a new study. (
  • Co-author Dr Saul Cunningham, of the CSIRO, said the study was important because it filled a gap in research that had been created through bias towards studying bees. (
  • This study shows that while bees are usually the most efficient crop pollinators on a per visit basis, lots of other insects are involved, especially flies, wasps and beetles,' he said. (
  • These other insects are sometimes so numerous that can have a greater total effect than the bees. (
  • The researchers also found non-insects responded differently than bees to the landscape structure. (
  • While bees rely on hives and other structures that can be affected by environmental change, pollinating insects almost always lived closer to the plants either in the grass or shrubs. (
  • These small bees are important native insects of the western United States. (
  • They provide habitat for wild colonies of honey bees, and these colonies are important to their species' long-term survival. (
  • Bees belong to this order but are considered beneficial insects rather than pests. (
  • Examples of insects in this class are Lepidoptera (butterflies) and Hymenoptera (bees). (
  • Bees and butterflies are important in aiding crop pollination. (
  • This study is important because it shows bee keepers that they are ultimately responsible for honey bees', Dr Thompson told BBC Nature. (
  • Many insect pollinators, such as bees, are declining in number around the world. (
  • Water collection and consumption, other distinctive behaviors of bees, are important tasks performed by the worker bees to satisfy their own needs, maintain necessary temperature and humidity, and mix with pollen to make brood food 15 . (
  • Motor activity is also an important behavior of bees. (
  • Insects are mostly solitary, but some, such as certain bees, ants and termites, are social and live in large, well-organized colonies. (
  • An allergic reaction to a sting occurs when your body's immune system overreacts to substances called allergens in the venom of stinging insects such as bees, wasps, hornets, or fire ants. (
  • Why are bees important? (
  • Bees are very important because they are the leading pollinators in the world. (
  • All termites and ants and some species of wasps and bees are the only insect groups containing truly social species. (
  • In some insects, such as bees, unfertilized eggs become males and fertilized eggs females. (
  • As for insecticides, the B.t. based products (Dipel, Bioprotect, or BTK) are favoured by many because they are specific to caterpillars and will not kill beneficial insects, bees, etc. (
  • Digger bees, also called mining bees, are solitary insects that create small burrows in soil. (
  • Digger bees are important pollinators. (
  • Like digger bees, cicada killers are solitary insects but may build their nests in very close proximity to one another. (
  • Bees, butterflies, beetles and other insect varieties will be protected for future generations. (
  • Birds and insects often move pollen from flower to flower when gathering nectar and they are therefore called pollinators. (
  • Insect bites or stings may lead to mild irritation, itching, redness and swelling and may often go away within a few hours. (
  • Insect bites or stings may often be itchy and repeated scratching may lead to skin abrasions and predispose to skin infections. (
  • Welcome to the Healing Center for Insect Bites & Stings. (
  • What are Insect Bites and Stings? (
  • Get allergy shots to make you less sensitive to insect stings and reduce the risk of a severe allergic reaction ( anaphylaxis ). (
  • If you have had allergy tests that found one or more sensitivities to insect stings, allergy shots can prevent life-threatening reactions and also make you less worried about insect stings. (
  • What are allergies to insect stings? (
  • Only about 4 to 10 people out of 100 who have these kinds of reactions to insect stings go on to have a more serious, anaphylactic reaction. (
  • The majority of allergic reactions to stings are due to this order of insects. (
  • Stings are almost always provoked by firm, accidental contact, such as stepping on a worker, taking the insect into the mouth with food or drink, or pressing/striking a bee or wasp with the hand. (
  • Bites and stings of medically important venomous arthropods. (
  • Springtime also isn't without its risk of insect bites and stings. (
  • A pack of pocket-sized cards to help identify 100 species of insects found in gardens and the countryside. (
  • Mount a collection of 20 species of insects representing at least six different orders. (
  • Make colored drawings or paintings of 20 species of insects, representing at least six different orders. (
  • Take color photographs of 20 species of insects, representing at least six different orders. (
  • Effectively, this means the further north (or south) you go, the less species of insects there are. (
  • BASCOMB: There are some 800,000 known species of insects, and surely many more not yet discovered. (
  • Hover fly , (family Syrphidae), also called flower fly, or syrphid fly , any member of a family that contains about 6,000 species of insects in the fly order, Diptera . (
  • 8 November 2004, Rome -- Edible insects, like caterpillars and grubs, are important sources of protein and should be considered an alternative in efforts to increase food security in central African countries, FAO said today. (
  • Insects are widely offered in local village markets, while some of the preferred species, such as the Sapelli caterpillars reach urban markets and restaurants. (
  • The pupa is the third body form in the life cycle of insects that undergo complete metamorphosis (like caterpillars). (
  • A few insects (e.g., some caterpillars and aquatic midge larvae) tolerate ice formation in body fluids, although it is probable that the cell contents do not freeze. (
  • Grow the right flowers to attract these Top 10 beneficial insects to your garden to minimize damage from aphids, caterpillars, flea beetles and other pests. (
  • A non-exhaustive list of vendors who sell natural enemies can be found in ENTFact 124, "Vendors of Microbial and Botanical Insecticides and Insect Monitoring Devices" ( ). (
  • PETER H. ADLER is a professor of entomology at Clemson University, where he holds a teaching and research appointment, specializing in the behavior, ecology, genetics, and systematics of insects, particularly butterflies and medically important flies. (
  • This course introduces students to entomology, emphasizing the diversity of insects and their ecology and conservation biology. (
  • A calque of Greek ἔντομον [éntomon], "cut into sections", Pliny the Elder introduced the Latin designation as a loan-translation of the Greek word ἔντομος (éntomos) or "insect" (as in entomology), which was Aristotle's term for this class of life, also in reference to their "notched" bodies. (
  • Hundreds of insect scientists and entomology students will be meeting in Greenville, SC next week as members of the Southeastern Branch of the Entomological Society of America (ESA) get together for their 88th annual meeting at the Embassy Suites Greenville Golf & Conference Center, March 2-5, 2014.

  • The ability to increase productivity of insect populations that supply commercially important products such as dyes, silk, and honey and the deliberate introduction of insect diseases into populations of insect pests involves knowledge of microbiology and biochemistry as well as entomology. (
  • See 'Stinging insects: Biology and identification' and 'Entomology and control of imported fire ants' . (
  • Dr Rader said that with current global declines in bee populations, other, hardier insects that do not rely heavily on vulnerable habitat structures could provide a kind of 'pollination insurance' in the face of environmental change. (
  • We asked Thomas Seeley and Nick Haddad to sound off on why insect conservation is important, and to reflect on the magnitude of the loss of key populations. (
  • Parasitoids perform an important ecosystem service by suppressing pest populations. (
  • Air circulation in earth's atmosphere i.e Seattle's temperature is windier and generally more violent, so insect populations have less chance to settle in large colonies. (
  • There have been warning signs for years about plummeting insect populations worldwide, but the extent of the potentially "catastrophic" crisis had not been well-understood - until now. (
  • Help dwindling insect populations thrive across Avon. (

  • Coleoptera is the order for beetles, which are biting and chewing insects. (
  • Important families are Curculionidae (weevil proper), Chrysomalidae (leaf beetles), and Bruchidae (pulse beetles), which attack pods of legumes. (
  • Beetles are especially important because they do all the different jobs that we know different kinds of insects do. (
  • Thanks to the abundance and diversity of beetles, they are a great group to focus on when studying insect anatomy and physiology. (
  • MELILLO: Oh, yeah, I mean, insects symbolically have played important roles dating way back to scarab beetles and the ancient Egyptians. (
  • Of these insects, some (dipterans and some beetles) achieve very high wingbeat frequencies through the evolution of an "asynchronous" nervous system, in which the thorax oscillates faster than the rate of nerve impulses. (
  • Cutworms and flea beetles on canola are the insects of greatest concern currently. (
  • Adult soldier beetles feed on aphids and other soft-bodied insects, as well as on nectar and pollen. (
  • Soldier and carabid beetles work the night shift, emerging after dark from beneath rocks, mulch and other daytime hiding places to feast upon soft-bodied insects and the eggs of Colorado potato beetles. (
  • An international team led by Dr Romina Rader of the University of New England set out to determine, for the first time, how non-bee insects contribute to pollination of crops. (
  • Insect herbivores ( locusts , for example) eat many crops, causing problems for crop growth and for farmers. (
  • Insects pollinate our crops, of course, they're also used to make our apples shiny, our wood waterproof, and some candy just the right shade of red. (

  • Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. (
  • Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. (
  • All insects have a waxy ( lipid ) layer that coats the outer surface of the exoskeleton to prevent water loss from the body wall. (
  • After hatching, the insect must molt periodically as it grows, since the rigid exoskeleton does not allow much expansion. (
  • A new, soft exoskeleton forms beneath the old one, and after each molt the insect undergoes a rapid expansion before its new covering hardens. (
  • Hematophagy in insects contributes principally to reproductive success and has required substantial evolutionary adaptation to accommodate behavior, digestion, iron detoxification, proteins and lipid transport and water management, among other demands. (
  • Aggression is an innate behavior that is important for animal survival and evolution. (
  • Round after round of EFT was done using a dialogue about that particular wasp and all similar flying insects rather than any specific reminder phrase. (

  • Some insects are more likely than others to cause allergic or toxic reactions. (
  • Most adult insects have wings. (
  • Flies have two wings, but all other insects with wings have four. (
  • Two insect groups, the dragonflies and the mayflies , have flight muscles attached directly to the wings. (
  • Other insects have the flight muscles attached to the thorax, making it oscillate and indirectly causing the wings to beat. (
  • Some very small insects make use not of steady-state aerodynamics but of the Weis-Fogh clap and fling mechanism, generating large lift forces at the expense of wear and tear on the wings. (
  • Insects that beat their wings fewer than one hundred times a second use synchronous muscle. (
  • The overall effect is that many higher Neoptera can beat their wings much faster than insects with direct flight muscles. (
  • In other winged insects, flight muscles attach to the thorax, which make it oscillate in order to induce the wings to beat. (
  • Growth and development (molting metamorphosis) in a chironomid midge, a holometabolous insect. (
