Released en masse, sterile Mexican fruit flies can undermine a wild population of the fruit-damaging pests so that fewer applications of insecticide are needed. But the irradiation used to sterilize the flies weakens them, hindering their ability to outcompete wild-type males for female mates. Now, U.S. Department of Agriculture (USDA) and collaborating scientists have devised a hormone therapy for making sterile flies "more macho," improving their chances of mating with female flies...

New tray and rack system is expected to be able to successfully rear 140,000—175,000 adult mosquitoes per rack The requirement for efficient mosquito mass-rearing technology has been one of the major obstacles preventing the large scale application of the Sterile Insect Technique (SIT) against mosquitoes. However, according to a new article in the next issue of the Journal of Medical Entomology, scientists at the Untited Nations Food and Agriculture Organization (FAO) and the...

MSU Plan Would Control Deadly Tsetse Fly

For the first time, scientists have created a satellite-guided plan to effectively control the tsetse fly — an African killer that spreads “sleeping sickness” disease among humans and animals and wipes out $4.5 billion in livestock every year. Michigan State University researchers developed the plan using a decade´s worth of NASA satellite images of Kenyan landscape and by monitoring tsetse movement. With unprecedented precision, the plan can tell where and when to...

A new study published in the Journal of Economic Entomology shows that radiation can be used to effectively sterilize the light brown apple moth (LBAM), an insect pest found in Australia, New Zealand, California, Hawaii, Sweden, and the British Isles. The light brown apple moth, Epiphyas postvittana (Walker), feeds on apples, pears, stonefruits, citrus, grapes, berries and many other plants. A native of Australia, it has been found in California since 2007. The California Department of Food...

Genetically Modified Mosquito Could Help Battle Dengue Fever

Scientists have found that a genetically modified mosquito could help tackle dengue fever and other insect-borne diseases. Researchers found that the genetically modified males mated successfully with wild females in a dengue-affected part of the Cayman Islands. They said that mating has not been proven in the wild, and could cut the number of disease-carrying mosquitoes. The World Health Organization (WHO) believes there may be 50 million cases every year. Scientists realized in...

Combining pest-resistant cotton with the controlled release of sterile pink bollworm moths, a UA-led initiative has virtually rid Arizona of one the world's most damaging cotton pests Using pests as part of an insect birth control program helps to get rid of them, UA researchers find. A new approach that combines the planting of pest-resistant cotton and releasing large numbers of sterile moths has virtually eliminated of the world's most destructive cotton pests from Arizona. The novel...
