Effect of Ten Soybean Cultivars on Development and Reproduction of Lima Bean Pod Borer, Etiella Zinckenella (Lepidoptera: Pyralidae) Under Laboratory Conditions

The effect of ten soybean cultivars, glycine max (l.) (including, ‘clark’, ‘sahar’, ‘jk’, ‘032’, ‘033’, ‘williams’, ‘l17’, ‘zane’, ‘gorgan3’ and ‘dpx’) on developmental parameters and reproduction of the lima bean pod borer, etiella zinckenella treitschke (lepidoptera: pyralidae), was studied at 25±1°c, 60±5% rh and a photoperiod of 16:8 h (l:d). the larval period ranged from 13.42±0.10 days on ‘clark’ to 16.28±0.14 days on ‘033’. the female and male lifespans were longest on ‘032’ (55.84±0.27 and 56.80±0.10 days) and shortest on ‘clark’ (51.18±0.11 and 52±0.13 days), respectively. the oviposition period was longest on ‘clark’ (15.46±0.19 days) and shortest on ‘gorgan3’ (9.52±0.13 days). the mean number of eggs laid per female was significantly different among the cultivars, ranging from 11.21±0.22 eggs (on ‘jk’) to 16.16±0.56 eggs (on ‘clark’). based on development and reproduction parameters, it can be concluded that ‘clark’, ‘zane’, ‘williams’, ‘l17’ and ‘033’ might be the susceptible host plants and ‘dpx’, ‘sahar’, ‘032’, ‘jk’ and ‘gorgan3’ might be the partially resistant host plants for e. zinckenella.
