AbstractThe acceptability of host plant extracts on pith, charred filter paper, and an agar diet, and vacuum infiltrated into lettuce leaves was compared on three species of Lepidoptera and two of Coleoptera. The vacuum infiltrated lettuce was eaten by two of the Lepidoptera and it was the only method acceptable to the Coleoptera. The agar diet was eaten by the three Lepidoptera while pith and charred filter paper were acceptable to only two of them. It is concluded that vacuum infiltration of lettuce leaves is a useful method for the bioassay of host plant extracts to determine if they contain insect feeding token substances.

ABSTRACTBuchnera aphidicolais an obligate endosymbiont that provides aphids with several essential nutrients. Though much is known about aphid-Buchnerainteractions, the effect of the host plant onBuchnerapopulation size remains unclear. Here we used quantitative PCR (qPCR) techniques to explore the effects of the host plant onBuchneradensities in the cotton-melon aphid,Aphis gossypii.Buchneratiters were significantly higher in populations that had been reared on cucumber for over 10 years than in populations maintained on cotton for a similar length of time. Aphids collected in the wild from hibiscus and zucchini harbored moreBuchnerasymbionts than those collected from cucumber and cotton. The effect of aphid genotype on the population size ofBuchneradepended on the host plant upon which they fed. When aphids from populations maintained on cucumber or cotton were transferred to novel host plants, host survival andBuchnerapopulation size fluctuated markedly for the first two generations before becoming relatively stable in the third and later generations. Host plant extracts from cucumber, pumpkin, zucchini, and cowpea added to artificial diets led to a significant increase inBuchneratiters in the aphids from the population reared on cotton, while plant extracts from cotton and zucchini led to a decrease inBuchneratiters in the aphids reared on cucumber. Gossypol, a secondary metabolite from cotton, suppressedBuchnerapopulations in populations from both cotton and cucumber, while cucurbitacin from cucurbit plants led to higher densities. Together, the results suggest that host plants influenceBuchnerapopulation processes and that this may provide phenotypic plasticity in host plant use for clonal aphids.
