Biological control agents

Biological and Natural Controls. Parasites and predators are effective in limiting the numbers of pest Insects and plant pathogens both in nature and for crops (35). This basic fact led to the development of biological controls. For example, the vedalia beetle, which was Introduced for control of cottony cushion scale on citrus in California, has provided continuous effective control of this pest for many decades. Worldwide only approximately 1% of the pests have been effectively controlled by Introduced biological control agents (43). [Pg.317]

However, not all natural enemies are fully effective. For example, the gypsy moth has approximately 100 parasites and predators attacking it but the pest reaches outbreak levels periodically (35). Nearly 40 biological control agents were introduced from Europe and Asia to control the moth and 11 of these became established (44). Yet not one of the 11 blocontrol agents is providing fully effective control, although each contributes to some limitation of this pest. [Pg.317]

Chlorpyrifos inhibits substrate-borne reception and emission of sex pheromone in Tri-chogramma brassicae, an entomophagus insect massively used as a biological control agent of com borers, among survivors of an LC20 dose. Inhibition was probably due to nervous system effects and was not specific to pheromone communication (Delpuech et al. 1998). [Pg.889]

An extract taken from the composted straw of the alkaloid-rich lupin plants has produced very promising results in the development of biological control agents. The fungistatic activity of straw compost extracts increased markedly when the lupin straw used for composting was enriched with alkaloid extract. [Pg.196]
