Foraging behavior, host stage selection and gut content analysis of field collected Drapetis nr. divergens: a predatory fly of Bemisia argentifolii
2002
Hagler, J.R.
A laboratory investigation of the foraging behavior and host stage selection of field collected Draptis nr. divergens presented with a surfeit of silverleaf whitefly, Bemisia argentifolii Bellows and Perring, eggs, nymphs and adults was undertaken. The foraging behavior of D. nr. divergens resembled that of an ambush attack strategist, frequently exhibiting motionless behavior and feeding exclusively on mobile adults. A gut content evaluation of D. nr. divergens using a whitefly-specific enzyme-linked immunosorbent assay (ELISA) was conducted on field collected flies. The analysis revealed that 15% of the individuais collected contained whitefly remains in their guts.
