Biological control of crop pests advanced with “lethal genetic sexing system” [Registered]

A new discovery promises to allow expanded use of a mainstay biological pest control method, which avoids the health, environmental and pest-resistance concerns of traditional insecticides, scientists are reporting. The advance toward broadening applicability of the so-called sterile insect technique (SIT) appears in the journal ACS Synthetic Biology. Luke Alphey and colleagues explain that the Lepidoptera, a large family of insects with a caterpillar stage, cause widespread damage worldwide to cotton; apples, pears and other fruits; and vegetable crops like broccoli, Brussels sprouts and cabbage. Farmers usually battle these pests with traditional insects, with little use of SIT, despite its…
