Tarantula Venom Protein May Serve As Bioinsecticide For Cotton Crop Pests
2013-09-12 10:10:21

Public Library of Science Spider venoms are usually toxic when injected into prey, but a new protein discovered in the venom of Australian tarantulas can also kill prey insects that consume the venom orally. The protein is strongly insecticidal to the cotton bollworm, an important agricultural pest, according to research published September 11 in the open access journal PLOS ONE by Glenn King and Maggie Hardy from the Institute of Molecular Bioscience at the University of Queensland,...

Scientists have developed Bt toxins for the management of Bt resistance in European corn borer and other crop pests. Toxins from Bacillus thuringiensis bacteria (Bt toxins) are used in organic and conventional farming to manage pest insects. Sprayed as pesticides or produced in genetically modified plants, Bt toxins, used in pest control since 1938, minimize herbivory in crops, such as vegetables, maize or cotton. Since 1996, Bt producing transgenic crops have been grown, which...

The creation of compounds that disrupt a worldwide pest´s winter sleep hints at the potential to develop natural and targeted controls against crop-eating insects, new research suggests. Scientists have designed agents that interfere with the protective dormancy period of the corn earworm, a species that infests more than 100 types of plants and costs American farmers an estimated $2 billion a year in losses and control costs. The compounds, composed of synthetic molecules that...

BASEL, Switzerland, July 14 /PRNewswire-FirstCall/ -- Syngenta and Bayer CropScience have entered into a long-term business agreement relating to a key plant biotechnology trait. Under the agreement, Syngenta has granted Bayer CropScience a worldwide, non-exclusive license for use of VIPCOT(TM) insect control technology in cotton. The VIPCOT technology expresses two insecticidal proteins that are highly effective against a number of important cotton pests, including cotton bollworm...

Climate change could provide the warmer weather pests prefer, leading to an increase in populations that feed on corn and other crops, according to a new study. Warmer growing season temperatures and milder winters could allow some of these insects to expand their territory and produce an extra generation of offspring each year, said Noah Diffenbaugh, the Purdue University associate professor of earth and atmospheric sciences who led the study. "Our projections showed all of the species...

The larva of the moth Helicoverpa zea is a major agricultural pest for cotton (where it is known as the cotton bollworm), corn (where it is known as the corn earworm), tomatoes (where it is the tomato fruitworm), and many other crops. The adult moth, pictured here is a pollinator. It is very cosmopolitan in what plants it will use as larval food.
