The susceptibility of Aphis gossypii (Glover) reared on watermelon or cotton to seven insecticides was determined using a Petri dish bioassay. Baseline susceptibility values to each insecticide for susceptible laboratory A. gossypii colonies varied between host plants, but aphids reared on cotton were generally more tolerant to insecticides than aphids from watermelon. The ratio of relative susceptibility of cotton aphids to melon aphids was as much as 1000 with dimethoate or 415 with bifenthrin, however, no significant differences in susceptibility was observed with chlorpyrifos between aphid populations from the two host plants. Orders of toxicity for the seven insecticides varied between host plant, but on watermelon, the order of toxicity was bifenthrin > oxydemeton-methyl > methomyl > dicrotophos > dimethoate > chlorpyrifos > endosulfan. Because of the wide range of response to insecticide doses observed with bifenthrin on melon aphid and with dimethoate and endosulfan against cotton aphid, use of the Petri dish bioassay method as a discriminating-dose field bioassay for these insecticides may not provide consistent estimations of the resistant nature of field populations. Bioassay data taken at 3 h were generally more consistent and provided a more predictive mortality model than those taken at 2 or 4 h for most insecticides. LC50 values estimated for dimethoate with melon aphids using leaf-spray or leaf residue bioassays differed little from LC50 values estimated with the Petri dish bioassay. Because Petri dish bioassays cost less than half as much as plant-based bioassays, provide comparable results, and require less assay time, this method is more suitable for use in monitoring for insecticide resistance in melon aphid.

An Evaluation of the Parasitoid, Aphidius colemani Viereck (Hymenoptera: Braconidae) and the Predator Aphidoletes aphidimyza Rondani (Diptera: Cecidomyiidae) for Biological Control of Aphis gossypii Glover (Homoptera: Aphididae) on Cucumber

Developmental time and fecundity of Aphidius colemani Viereck and Aphidoletes aphidimyza Rondani were studied under laboratory conditions on cucumber plants infested with Aphis gossypii Glover at a constant temperature of 20° C, photoperiod of 18 hours and 70% R. H. Developmental time from egg to adult for A. colemani lasted 13.9 days and for A. aphidimyza, from egg to larva was 3 days, larva to pupa 5.8 days, from pupa to adult 11.9 days, and total developmental time was 20.6 days. The average lifetime fecundity was 57.7 for A. colemani and 55.07 for A. aphidimyza. The variation for both species was considerable. Percentage of females for A. colemani was 58% and for A. aphidimyza 66%. One larva of A. aphidimyza will, on average, kill 23.8 A. gossypii during its life. Predation of parasitized aphids by A. aphidimyza was observed. Production of parasitoids was lower when the predator was present. The use of the two natural enemies together in control programs against A. gossypii is discussed.
