Survival and Movement of Insect Parasitic Nematodes in Poultry Manure and Their Infectivity Against Musca domestica
Abstract
Survival, infectivity, and movement of three insect parasitic nematodes (Steinernemafeltiae All strain, S. bibionis SN strain, and Heterorhabditis heliothidis NC strain) in poultry manure were tested under laboratory conditions. The majority (70-100%) of the nematodes died within 18 hours after exposure to the manure. Nematodes exposed to manure slurry for 6 hours killed at least 95% of the house fly larvae, Musca domestica, but nematodes exposed for 12 hours achieved less than 40% larval mortality. The majority (90-97%) of the three nematode species applied to the manure remained on the surface. Poor survival and limited movement of nematodes in poultry manure appear to make them unlikely candidates for biocontrol of filth flies in this habitat. Key words: biological control, insect parasitic nematode, house fly, infectivity, movement, survival.Downloads
