O. Ayoade et al., METAMORPHOSIS AND WING FORMATION IN THE BROWN PLANT HOPPER, NILAPARVATA-LUGENS, AFTER TOPICAL APPLICATION OF PRECOCENE-II, Archives of insect biochemistry and physiology, 32(3-4), 1996, pp. 485-491
In the present paper the effects of precocene on N. lugens strains obt
ained by successive selection for adults with specific wing form under
highly crowded conditions over 70 generations are reported. When prec
ocene II was applied, macropterous adults developed from presumptive b
rachypters. Our results also demonstrated the disruptive effects of pr
ecocene II on metamorphosis, and we report here the induction of preco
cious metamorphosis in N. lugens in details for the first time. The se
nsitive periods to precocene II, affecting wing dimorphism and metamor
phosis, differed between the two strains. (C) 1996 Wiley-Liss, Inc.
