Effects of Some Anti-Juvenile Hormone Agents (Precocene-2, J-2710, KK-110) on Postembryonic Development ofNeobellieria bullata

Assessment of the toxic and disruptive effects of Precocene II on growth and metamorphosis of the grasshopper Euprepocnemis plorans plorans (Charp.) (Orthoptera: Acrididae).

“…In Coleoptera, topical application of PI and PIІ onto the 2 nd larval instar of L. decemlineata induced the precocious adultoids (Farazmand and Chaika, 2008). In addition, precocious metamorphosis had been induced by precocenes in several insects of Diptera, such as the flesh fly Neobellieria bullata (Darvas et. al., 1990) and the house fly Musca domestica (Gaur and Kumar, 2009); as well as Lepidoptera, such as the tobacco cutworm Spodoptera litura (Srivastava and Kumar, 1999) and P. ricini (Khan and Kumar, 2000).…”

“…Moreover, other anti-JH compounds induced such feature of impaired metamorphosis in various insects, such as Fluoromevalonate (FMev) against the fall webworm Hyphantria cunea (Farag and Varjas, 1983) and the lawn armyworm Spodoptera mauritia (Balamani and Nair, 1989); ETB (Kuwano et al, 1988), KK-42 (Kuwano et al, 1985;Akai and Mauchamp, 1989), KK-22 (Asano et al, 1984) and 3-pyridine derivatives (Yoshida et al, 2000) against B. mori. Treatment of N. bullata larvae with KK-110 and J-2710 resulted in precocious pupation (Darvas et. al., 1990).…”
