Evaluations of biological control agents are conducted primarily in the field, and when necessary, aspects of both pest and natural enemy biology and behavior are studied in the laboratory. The emphasis of my work is to identify pest problems where biological control could be successful, locate and release natural enemies, and then evaluate natural enemy impact on pest population growth. Biological control is also being used in conservation efforts to restore natural areas invaded by exotic organisms, especially weeds. Many of our current agricultural pest problems are amenable to biological control, and when successful, natural enemies provide enduring, environmentally benign, pest control. More.īiological control is the intentional use of host specific natural enemies (predators, parasitoids, and pathogens) by humans to suppress population growth of noxious plants and animals to levels which are no longer damaging. Because New Zealand lacks a significant native terrestrial mammal fauna it subsequently lacks an essential co-evolved insect community associated with. New Zealand is an agriculturally intensive country that relies heavily on dairy cattle and sheep farming to generate income. is found from avocado seeds collected in Puerto Rico, Mexico and Guatemala. Icerya purchasi Maskell, or Cottony Cushion Scale is an exotic plant pest in the Galapagos Islands.

Trioza induce galls that develop on the upper or lower leaf surface or cause leaf margins to roll. The avocado fruit galling midge causes damage to pods by feeding in immature fruiting bodies.
