Feeding preference, fecundity and egg hatch of rice stink bug on artificial diet, rice and alternate host grasses
Southwestern Entomologist 30 (4), 257-257
Abstract: Feeding preference, mating frequency, fecundity and egg hatch of rice stink bug, Oebalus pugnax (F.) were examined in the laboratory. Adult rice stink bugs were allowed to feed on one of five different food sources including rice, Oryza sativa L.; barnyardgrass, Echinochloa crusgalli (L.); dallisgrass, Paspalum dilatatum Poir.; ryegrass, Lolium spp; and a new artificial rice flour diet. Initially, a higher percentage of females fed on all food sources than did males. Ryegrass and dallisgrass were fed on less frequently than rice or bamyardgrass. The insects mated twice as frequently and laid more eggs on rice panicles than on rice flour diet. However, rice flour diet was comparable to ryegrass and dallisgrass both in mating frequency and number of eggs laid per female. Egg hatch was higher from females reared on natural hosts than on rice flour diet. However, percentage egg hatch was similar for females fed rice flour diet or ryegrass. Rice flour diet may provide an acceptable alternate food source for rice stink bug adults in the laboratory but needs to be improved to make it as acceptable as barnyardgrass or rice.
