Abstract

The pink bollworm,Pectinophora
gossypiella, is a dangerous pest of cotton worldwide, The objective of the
current study was to evaluate the disruptive effects of the chitin synthesis
inhibitors, noviflumuronand novaluron, on the adult performance and
reproductive potential of this pest after treatment of1-day old eggs
with sublethal concentrations of noviflumuron(4.0, 2.0, 1.0 and 0.5
ppm)and novaluron (1.0, 0.5, 0.1 and 0.05 ppm). The adult emergence was
considerably blocked by both compounds but they failed to affect the adult
survival or morphogenesis. The total adult longevity was remarkably shortened.
Noviflumuron treatment caused a slight prolongation or shortening of
pre-oviposition period, depending on the concentration but novaluron treatment
led to slightly prolonged period. The oviposition period was remarkably
shortened. Prolonged post-oviposition period was recorded by both compounds. The oviposition efficiency was significantly
prohibited, regardless the tested compound. Fecundity of the successfully
reproducing females and fertility of eggs laid by these females were
drastically reduced. The incubation period of eggs was considerably prolonged
by both compounds.
