As you identify and address specific pest problems, you can fine-tune your farming practices to attract, retain or enhance populations of beneficials for your specific situation. Answer the questions about the […]

To design an effective plan for successful habitat management, first gather as much information as you can. Make a list of the most economically damaging […]

It promotes diversity which in turn sustains a farm’s soil fertility, productivity and crop protection. Innovative approaches that make agriculture both more sustainable and more productive are flourishing around the world. […]

They note that normal applications of Bt — one-time, high-level doses — may kill some nontarget insects, but plants with Bt in their stalks, leaves and pollen can poison nontarget insects — including beneficials — throughout the […]

Thousands of species of bacteria, fungi, viruses, protozoa and nematodes can sicken or kill insects. Even if the insects survive, the pathogens’ “sub-lethal” effects can keep their victims from feeding or reproducing. Bacteria. Most bacteria infect […]

Parasitoid diversity is directly related to plant diversity: different crops, ground covers, weeds and adjacent vegetation support different pests, which in […]

Entomologists have described more than 18,000 species of dipteran, or fly, parasites, which have diversified over an expansive range of hosts (Table 5). Unlike parasitic wasps, most species of parasitic flies lack a hardened structure with which to deposit eggs inside their hosts. Instead, they lay their eggs or larvae on […]

Parasitoids can be specialists, targeting either a single host species or several related species, or they can be generalists, attacking many types of hosts. Typically, they attack hosts […]
