Abstract: Experimenfs c o r n e d in West Java, indonesia investigated the developmentat biology and reproductbe behavior of two sympatric soybean pod borers.Etiefla zinckenalla Trietschke and E-hobsoni Butler ( t epi dopt er a: Pyratidae).It was determined that 1) significant interspecies differences occurred between the egg, larval, pupal, and total egg-to-adult developmental periods of laboratory raised Ezkckenella and E. hubsoffk 2) the pie-pupal and total egg-to-adutt dwebpmentai periods of female E. zinckenella were significantly shorter than for males; 3) the longevity of virgin-female E-zinckenella was significantly bnger than that of virgin-male E. zinckenell$ or v i r g i k m k and female E. hobsoni; 4; interspecies differences occurred in the female: male sex-ratios of laboratory raised adults; 5) peak mating for both species occurred on the s m r d t?igM &ei & S G ~; 6) infeispedes b i e r e m s OIX~~R& in the temporal distribution of catling and mating behaviors; 7) repeated rrating was observed for both species at a very low frequency; 8) interspecific mating did not occur; 9) female E. zinckenella were significantly more fecund (1 60.8 2 49.0 eggs) than E. hob& (32.5 + 16.9 eggs); 10) the duration of copulation of E. zinckenella (123-6 + 12.5 min) was sigirificantty longer than that of E. hobsoni (73.7 f 1 6.1 min); 11) virgin-fernate baited traps caught only conspecific males, and reduced numbers of males were captured in traps simultaneousty baited with virgin-females of each species; 12) wing-traps baited with two conspecific virgin-females caught ( Z f SE) 2.65 + 0.41 male E. aLInckene/la and 1.61 .+0.40 mak E. hobsoni per night; 13) the greatest number of males of both species were caught in traps placed at, or above the canopy level; and 14) no males were attraed to traps baited with synthetic candidate pheromone blends previously demonstrated to be altractE/e to E. dIldcene1l.a in Egypt and Hungary.This report demonstrates distinct biological differences and r e p r m v e isold-on between the two Etiella spp.and suggests that E. zinckenel... in Indonesia is gene-6Hereni from E. zinckenella in Europe and North Africa.
