All About Squash Bugs
The squash bug is the common name of several species of insects from the Coreidae family. The most famous representative is Anasa tristis. They are widespread throughout North America, even in southern Canada. They most often attack pumpkins and gourds, and the vector is bacterial diseases of the yellow vine. They are also known for the unpleasant smell they emit when they rot.
The complete life cycle of a squash bug lasts about six to eight weeks. They have a complete transformation that includes the egg stage, nymphs and adult form. In the northern climate they have one generation per year, while in warmer regions they can have up to three generations per year. This insect overwinters in an adult form, most often under the remains of crops, soil, stones, and the like.
The adult is about 1.5 cm (0.59 inch) long, dark gray, brown or black. Adults survive on average up to 130 days. The squash bug most often attacks zucchini and squashes we mentioned earlier. It also feeds on houseplants. The leaves wither, turn black and die. The amount of damage depends on the number of individuals present.
There are several natural enemies of the squash bug, mostly egg parasitoids. The most famous is from the order of Hemiptera and Diptera, which develop into an adult and kill it.
