This is sometimes known as summit disease because infected insects climb to the upper part of a plant and grip the tip of the stem as they die; this ensures widespread dispersal of the fungal spores.

Besides removing the insects by hand or including trap plants to lure away bugs, you can bring in (native) ladybugs as well. A ladybug larva can eat 50 aphids a day. A ladybug larva can eat 50 ...

Nontarget effects on some insects (predatory and detritivorous beetles, some parasitic wasps and bees) were also found in field trials of fipronil for desert locust control in Mauritania, and very low doses (0.6-2.0 g a.i./ha) used against grasshoppers in Niger caused impacts on nontarget insects comparable to those found with other ...
