From 1996 to 2001, herbicide tolerance was the most dominant trait introduced to commercially available transgenic crops, followed by insect resistance.

With pyrethrum in short supply, DDT was used extensively during World War II by the Allies to control the insect vectors of typhus — nearly eliminating the disease in many parts of Europe.

During and just after World War II, DDT was used as insecticide to combat insect vectors carrying malaria and typhus.

Over £ 150m is spent annually on Japanese knotweed control, and a decision was taken on 9 March 2010 in the UK to release into the wild a Japanese psyllid insect, Aphalara itadori.

A study of fruit fly wings designed to understand how the wings produce lift was performed using a large tank of mineral oil and wings 100 times larger than actual size, in order to slow down the wing beats and make the vortices generated by the insect wings easier to see and understand.

Like Robert Boyle and Nicolaas Hartsoeker, Van Leeuwenhoek was interested in the dried cochineal, trying to find out if the dye came from a berry or an insect.

" But Duke University insect developmental biologist Fred Nijhout said that the paper was better suited for the " National Enquirer than the National Academy.

The true source of the pigment, an insect, was kept secret until the 18th century, when biologists discovered the source.

A cicada ( or ) is an insect of the order Hemiptera, suborder Auchenorrhyncha ( which was formerly included in the now invalid order Homoptera ), in the superfamily Cicadoidea, with large eyes wide apart on the head and usually transparent, well-veined wings.

Apis mellifera, the most commonly domesticated species, was the third insect to have its genome mapped.

A patent was awarded in 2012 for an insect repelling device using Osage orange.

Upon collection of the maggot mass, only one insect, Chrysomya megacephala, was discovered.

In the 1940s, it was realised that two species of scale insect, Lepidosaphes newsteadi and Carulaspis minima, had accidentally been introduced, and were rapidly killing off the junipers, which had no immunity to their toxicological effect.

In 1977, a new insect infestation was discovered in the back of the panel as a result of crosspieces installed to keep the painting from warping.

Introduced to the UK in 1752, it was noted that the foliage of the American elm was far more susceptible to insect damage than native elms.

From this and the requirement to use the names of birds or insect for fighter aircraft, their first in-house fighter design was the Boulton Paul Bobolink.

Thus it was shown that clover used as a ground cover had the same disruptive effect on eight pest species from four different insect orders.

Hypermetamorphosis in different insect orders is analogous and not homologous ; for example hypermetamorphosis in the Acroceridae was not derived from the Strepsiptera, much less the Ephemeroptera.

Rimsky-Korsakov relates some of Balakirev's extremes in behavior at this point — how he had " given up eating meat, and ate fish, but ... only those which had died, never the killed variety "; how he would remove his hat and quickly cross himself whenever he passed by a church ; and how his compassion for animals reached the point that whenever an insect was found in a room, he would carefully catch it and release it from a window, saying, " Go thee, deary, in the Lord, go!

Ash trees in the United States are now under attack from the Emerald Ash Borer, an invasive insect species native to Asia and first detected in Michigan in 2002.

Bacteria belonging to this genus have been detected in a variety of environments such as: soil, water, rhizosphere, vegetable matter, forage and insect larvae, as well as clinical samples.

The Australian and I both were wearing insect repellent and were not badly bothered by insects, but my eyes watered as we stood watching the aborigine.

This can be accomplished substantially by a continued trend toward better facilities and techniques for fire control and more resources to cope with critical fire periods, and a more intensive application of a program of prevention, detection, and control of insect and disease infestations.

However, algorithms are also implemented by other means, such as in a biological neural network ( for example, the human brain implementing arithmetic or an insect looking for food ), in an electrical circuit, or in a mechanical device.

The gametes are taken up by the insect vector during a blood meal.

The disease is caused by the Francisella tularensis bacterium, and can be contracted through contact with the fur, inhalation, ingestion of contaminated water or insect bites.

In this form, the Bt toxin occurs as an inactive protoxin, which requires digestion by an insect to be effective.

Bt corn is now commercially available in a number of countries to control corn borer ( a lepidopteran insect ), which is otherwise controlled by spraying ( a more difficult process ).

Traits that have been engineered into corn include resistance to herbicides and resistance to insect pests, the latter being achieved by incorporation of a gene that codes for the Bacillus thuringiensis ( Bt ) toxin.

It is estimated that one third of the human food supply depends on insect pollination, most of which is accomplished by bees, especially the domesticated European honey bee.

In 1996 Charlie Ellington at Cambridge University showed that vortices created by many insects ’ wings and non-linear effects were a vital source of lift ; vortices and non-linear phenomena are notoriously difficult areas of hydrodynamics, which has made for slow progress in theoretical understanding of insect flight.

This oxygen level probably increased wildfire activity, as well as resulted in insect and amphibian gigantism -- creatures whose size is constrained by respiratory systems that are limited in their ability to diffuse oxygen.

The petioles and leaves are removed and harvested ; celery is packed by size and quality ( determined by colour, shape, straightness and thickness of petiole, stalk and midrib length and absence of disease, cracks, splits, insect damage and rot ).

T. cruzi is commonly transmitted to humans and other mammals by an insect vector, the blood-sucking " kissing bugs " of the subfamily Triatominae ( family Reduviidae ) most commonly species belonging to the Triatoma, Rhodnius, and Panstrongylus genera.

Beetles are by far the largest orders of insects, with 350, 000 – 400, 000 species in four suborders ( Adephaga, Archostemata, Myxophaga, and Polyphaga ), making up about 40 % of all insect species described.

DDT resistance is also conferred by up-regulation of genes expressing cytochrome P450 in some insect species.

The primary endosymbionts are thought to help the host either by providing nutrients that the host cannot obtain itself, or by metabolizing insect waste products into safer forms.

); a homemade shelter-ventilating pump ( a KAP ); large containers for water ; a plastic bottle of sodium hypochlorite bleach ; one or two KFMs and the knowledge to operate them ; at least a 2-week supply of compact, nonperishable food ; an efficient portable stove ; wooden matches in a waterproof container ; essential containers and utensils for storing, transporting, and cooking food ; a hose-vented 5-gallon can, with heavy plastic bags for liners, for use as a toilet ; tampons ; insect screen and fly bait ; any special medications needed by family members ; Pure potassium iodide, a 2-oz bottle, and a medicine-dropper ; A first-aid kit and a tube of antibiotic ointment ; long-burning candles ( with small wicks ) sufficient for at least 14 nights ; an oil lamp ; a flashlight and extra batteries ; and a transistor radio with extra batteries and a metal box to protect it from EMP.

Some specialists recommend using seaweed mulch or spray on the plants and minimize the insect habitat by cleaning the garden area of debris and weeds.

The invertase is one of these enzymes synthesized by the body of the insect.
