Tomato Fruitworm
1.
Sanitation. Collect and dispose of any infested fruit before the insect completes its life cycle.
2.
Introduce parasitic wasps. Do not remove parasitized caterpillars. Instead, leave them to assist as a natural, biological control.
3.
Dusting with diatomaceous earth may kill larvae.
4.
Use of a biological pesticide such as Bt can kill larvae during the warmest months.
5.
Use chemical pesticides. The pest has developed a resistance to many pesticides but the following pesticides are often used: esfenvalerate (Asana), methomyl (Lannate), azinphos-methyl (Guthion),
carbaryl (Sevin), or
pyrethrin. These must be applied before the worm enters the fruit.
6.
Minimize local food sources. Avoid planting tomatoes near corn or other hosts of the fruitworm to minimize populations.
