摘要

The Andean potato weevil consists of at least 14 species with 12 in the genus Premnotrypes and two in two other genera. The most important species attacking potato are Premnotrypes suturicallus Kuschel, P. vorax Hustache, and P. latithorax (Pierce). The weevil larva feeds and develops within the potato tuber resulting in yield loss. Although the weevil is native to the Andes, no parasitoids have been identified but predators like carabids affect the weevil population. In addition, entomopathogenic fungal and nematode species have been isolated in nature from these weevils. The fungus, Beauveria bassiana (Balsamo) Vuillmen, has been evaluated against the larvae and adults in the laboratory and field. Although effective under laboratory conditions, B.bassiana was not effective against weevil adults in the field because of the cold temperatures in the high Andes where potatoes are grown. It did show potential to control the weevil adults in potato storage areas, but its application did not provide sufficient benefits to farmers to adopt this biological control agent. On the other hand, the entomopathogenic nematode, Heterorhabditis species Alcazar-1, appears to be a potential candidate for biological control of the weevil. Its natural association with the Andean potato weevil complex, adaptation to cold, high virulence, superb host-finding abilities, high recycling potential and ease of mass rearing makes it a promising resource for Andean potato fanners. To be a practical control agent for large farms, investigations into large-scale production technologies for nematodes are required, whereas farmers with small farms could profit from the application of insect cadavers containing the nematode.
