The effect of the presence of the Indianmeal moth, Plodia interpunctella (Hübner), on the capture of the almond moth, Cadra cautella (Walker), in pheromone-baited traps was evaluated. It was found that when both sexes of each species were released into a large warehouse simultaneously, the capture of male C. cautella was reduced to 5.5 ± 0.8 in traps baited with a two-component lure as compared to 11.4 ± 2.2 when only C. cautella were released. This decrease in response may have been caused by an inhibitory substance produced by the female P. interpunctella that affects the response of male C. cautella to the pheromone or confusion caused by an increase in the amount of pheromone present. This reduced response of C. cautella must be considered when using pheromone-baited traps to estimate population levels when both species are present.

Red Flour Beetles

Runner variety peanuts treated with four rates of diatomaceous earth (28.4, 56.8, 85.2, and 113.6 g per 12.7 kg peanuts) and Virginia variety peanuts treated with four Bacillus thuringiensis formulations (Dipel, Foil, M-Trak and Trident) were held for 8 months at ambient conditions in south Georgia and infested with stored-product insect pests. No red flour beetle, Tribolium castaneum (Herbst), adults were found in peanuts treated with diatomaceous earth until six months after treatment. After 8 months, red flour beetle populations in peanuts treated with diatomaceous earth ranged from 5.7 ± 1.9 to 32.8 ± 12.0 per kg, as compared to 221.2 red flour beetles per 12.7 kg peanuts in untreated controls. The effect of diatomaceous earth on red flour beetles was described by non-linear regression. Indianmeal moth, Plodia interpunctella (Hübner), and almond moth, Cadra cautella (Walker), populations were not abundant in untreated controls or the diatomaceous earth treatments. After 8 months, red flour beetle populations in peanuts treated with the four biological insecticides were not significantly different from the untreated controls. Low levels of Indianmeal moth and almond moth were present in all treatments.

Inshell peanuts treated with 10, 14, 18, and 22 ppm cyfluthrin were bioassayed with fifth instar Indianmeal moths, Plodia interpunctella (Hübner) and fifth-instar almond moths, Cadra cautella (Walker), after 0, 2, 4, 6, and 8 months of storage. Emergence of the adult almond moth was greater than Indianmeal moth emergence at residual bioassays of 14, 18, and 22 ppm. Regression of increasing emergence with storage time was significant for the Indianmeal moth at 22 ppm and the almond moth at 14 and 22 ppm. For both species, adult emergence decreased as cyfluthrin concentration increased and was described by quadratic regression.

Two commercially available sex pheromone lures, a rubber septum and a controlled release membrane, that were impregnated with (Z,E)-9-12-tetradecadien-1-yl-acetate, were tested for efficiency and longevity in capturing released Indianmeal moths, Plodia interpunctella (Hübner), and almond moths, Cadra cautella (Walker), in a large warehouse. When both species were released simultaneously, traps baited with both types of lures captured 19–20% of the Indiandmeal moths but captured less than 1% of the almond moths. The lures remained attractive for over 40 wks.

A biological control test in experimental peanut storages indicated that release of large numbers of the warehouse pirate bug, Xylocoris flavipes (Reuter) (Hemiptera: Anthocoridae), a generalist predator of stored-product insects, has considerable potential for suppression of stored-product moth populations. Suppression of the almond moth, Cadra cautella (Walker), and the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), was dependent on both the prey species and environmental conditions. Release of X. flavipes suppressed small populations of almond and Indianmeal moths by as much as 78.8% and 71.4%, respectively, before cold weather and a severe freeze eliminated the almond moth population in January. Suppression of the Indianmeal moth lasted through the 7-month test period. X. flavipes may be useful as one component of an integrated peanut control program based on release of biological agents
