Feasibility of controlling citrus red spider mite, Panonychus citri (Acarina: Tetranychidae) by green lacewing, Mallada basalis (Neuroptera: Chrysopidae)
Chinese Journal of Entomology 12 (2), 81-89
Abstract: Field releases of chrysopid for the control of spider mite, Panonychus citri on citrus, were initiated in Oct. 1990. One thousand chrysopid eggs were packed in each cardboard cup, and placed on trees upon hatching. 5-10 days later significant lower numbers of mites were found on M. basalis released trees than on controls (p < 0.05). This indicates that M. basalis is potentially an effective natural enemy of mites. Toxicities of 37 pesticides on M. basalis were tested. Most of the tested acaricides and fungicides are nontoxic to this predator, but all of the tested insecticides, including 3 acaricides (Amitraz, Propargite, Azocyclotin) are harmful. Nissol (acaricide) and sulfur (fungicide) are slightly harmful to this predator. Notes on care and raising of M. basalis and the effect of cold storage on mortality are also included.
