90 Squash Bug (Anasa tristis)
Anasa tristis is a serious agricultural pests that can be found on various members of the gourd family Cucurbitaceae, but most often occurs on pumpkins and squashes. Some varieties and cultivars are more susceptible to attack than others.
It is a true bug that feeds by sucking sap, mainly from the leaves, but sometimes also the fruit. In the process of doing this the insects inject toxic saliva into the plant tissues which causes them to wilt, darken in colour and die. The heavier the infestation, the greater the damage to the plant. Sometimes one plant or part of a plant can be heavily attacked while surrounding plants are untouched
