RESPONSES TO AZADIRACHTIN AND PYRETHRUM BY TWO SPECIES OF BEMISIA (HOMOPTERA: ALEYRODIDAE)


Author(s): TOSCANO NICK, YOSHIDA HARVEY A , HENNEBERRY THOMAS J
Interpretive Summary:
The number of SLW females that alighted on control versus azadirachtin-treated plants was not significantly different in all but 1 instance. When given a choice, significantly fewer SPW females landed on azadirachtin-treated plants at observation hours 6, 8, and 24. In no-choice trials, numbers of SPW females alighting on control versus azadirachtin-treated plants were equivalent throughout the entire test period. Moreover, although SLW oviposited equal numbers of eggs on control and azadirachtin-treated plants in choice and no-choice trials, SPW females laid significantly fewer eggs on plants treated with azadirachtin. Percentage nymphal establishment of SLW on control versus azadirachtin-treated plants was not significantly different in choice and no-choice trials. Although the percentages of established SPW nymphs were the same on control and azadirachtin-treated plants in the no-choice test, a significantly lower percentage of nymphs were found on treated plants in the choice trials.
