If you have something like aphids or thrips, where there are thousands on a plant, it's kind of hard to release enough sterile insects to do any good,

#New dual resistant tomatoes fight lethal pests with one-two punchin the battle against thrips Cornell breeder Martha Mutschler-Chu has developed a new weapon:

Thrips are tiny insects that pierce and suck fluids from hundreds of species of plants including tomatoes grapes strawberries and soybeans.

If some thrips get through with the virus the virus resistance genes are there to mop it up Mutschler-Chu said.

The Cornell thrips-resistant tomato lines with and without the virus resistance genes will be used by Mutschler-Chu

and an interdisciplinary team of eight other scientists from seven other institutions nationwide as part of a new five-year $3. 75 million project to control thrips and TOSPO viruses in tomatoes.

For the experiments UF and USDA researchers brought two types of thrips--tiny insects that often feed on plants--from Brazil to Florida laboratories.

Both thrips feed on the Brazilian peppertree but scientists found Ouro Preto was more cold-tolerant than a thrips from farther north in Brazil.

Scientists predict the insect will thrive in Florida where temperatures sometimes dip below freezing which is only slightly colder than the insect is used to. â#oethe idea of biological control is to reunite these highly specialized natural enemies with their host plant in this case Brazilian peppertree to help reduce plant densities in the invaded areaâ#said Veronica Manrique a UF

and reproduction in Florida. â#Scientists will now seek permission to release the thrips into areas Brazilian peppertree is growing.
