Only two families of parasitoid Hymenoptera parasitize eggs and larvae, the Eulophidae and the Trichogrammatidae. Other biocontrol agents of adults and larvae include anthocorid bugs of genus Orius, and phytoseiid mites. Biological insecticides such as the fungi Beauveria bassiana and Verticillium lecanii can kill thrips at all life-cycle ...
The larva feeds on the host's tissues until ready to pupate; by then the host is generally either dead or almost so. A meconium, or the accumulated wastes from the larva is cast out as the larva transitions to a prepupa. [12] [13] Depending on its species, the parasitoid then may eat its way out of the host or remain in the more or less empty ...
An aphid infestation can ruin a garden. Learn what causes aphids and how to identify, kill, and control them naturally for healthy plants with no aphid holes.
The larvae of Diptera feed on a diverse array of nutrients ; often these are different from those of adults, for instance the larvae of Syrphidae in which family the adults are flower-feeding are saprotrophs, eating decaying plant or animal matter, or insectivores, eating aphids, thrips, and other plant-sucking insects.
