Abstract

The effect of 5 insect growth regulators (IGRs): 3 juvenile hormone analogues (JHAs), fenoxycarb, CGA 29-170 and Pro-Drone and two moult inhibiting compunds, Dawco 439 and R-20458 in addition to the organophosphate isoxathion was evaluated on the Florida wax scale. Treatment with 100 ppm induced good reduction in the population when the compounds were applied to the first generation. The effect extended to the following generation up to 8 months posttreatment and the juvenile hormone analogues showed superior effect over the moult inhibiting compounds and also the organophosphate. The influence of the IGRs on the oviposition was clearly obvious with both the JHA, fenoxycarb and the IGR, Dawco 439 since they completly prevented the scale maturity and oviposition.

Zusammenfassung

Es wurde die Wirkung von 5 Wachstumsregulatoren: 3 Juvenilhormon-Analogen, Fenoxycarb, CGA 29-170 and Pro-Drone sowie 2 Häutungshemmern, Dawco 439 und R-20458 im Vergleich zu einem Organophosphat, Isoxythion auf die Florida-Wachsschildlaus untersucht. Eine Behandlung mit 100 ppm führte zu guter Reduktion der Population, wenn die Substanzen gegen die 1. Generation ausgebracht wurden. Die Wirkung dehnte sich auf die folgende Generation bis 8 Monate nach Behandlung aus, wobei die Juvenilhormon-Analogen eine bessere Wirkung als die Häutungshemmer und das Organophosphat zeigten. Da die Hormon-Analogen und die Häutungshemmer die Eiablage vollständig verhinderten, ist ihre Eignung zur wirksamen Bekämpfung der Florida-Wachsschildlaus bewiesen.
