Seasonal abundance of the crapemyrtle aphid,Sarucallis kahawaluokalani, in relation to the pecan aphids,Monellia caryella andMonelliopsis pecanis and their common predators

Abstract

The seasonal abundance of the crapemyrtle aphid,Sarucallis kahawaluokalani (Kirkaldy), and the majority of its predators that are common with the yellow pecan aphid,Monelliopsis pecanis Bissel, and the blackmargined aphid,Monellia caryella (Fitch), were determined in norh Florida.S. kahawaluokalani populations were tri — and bimodal in the 2 years studied and peak populations ofS. kahawaluokalani preceeded those of the pecan aphid complex. Peaks in predator populations consisting of Coccinellidae, Syrphidae, Chrysopidae and Anthocoridae, either coincided with or occurred just afterS. kahawaluokalani peaks.
