Gall-inducing insect Gall-inducing insect A gall-inducing insect is any insect that can cause the growth of galls within plants. The term gall fly is also used to cover these species, although most are not true flies. There are several groups of insects that meet this description. They include the gall wasps, scales, gall midges, aphids, psyllids and certain species of leafminer flies. Galls are growth deformities induced in certain plants by various insects which are mostly species-specific. The gall's form or type depends on what organism is attacking the plant and where the plant is being attacked. Based on the form, there
Red imported fire ant species. Although parasitism pressures by these flies do not affect the ants' population density and activity, it has a small effect on a colony population. The strepsipteran insect "Caenocholax fenyesi" is known to infect male ants of this species and attack the eggs, and the mite "Pyemotes tritici" has been considered a potential biological agent against red imported fire ants, capable of parasitising every caste within the colony. Bacteria, such as "Wolbachia", has been found in the red imported fire ant; three different variants of the bacteria are known to infect the red imported fire ant. However, its effect on
