Efficacy of essential oils to control the Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)

Abstract In Iran, the Indian meal moth, Plodia interpunctella (Hübner), is one of the most important pests of such stored products as date fruits and pistachio nuts. Ozone was applied as a gas at four concentrations (0, 2, 3, and 5 ppm) for four different periods (30, 60, 90, and 120 min) on the immature stages of P. interpunctella. The results indicated that by increasing the concentration and exposure time, the rate of mortality increased for all tested stages. This study showed that 12-day-old larvae were more susceptible than other stages when exposed to 5 ppm ozone for 120 min. The next in order of susceptibility were pupae, then 5-day-old larvae, and 17-dayold larvae had the highest sensitivity to ozonation. At the highest concentration of ozone, for the longest time, the least mortality rate was recorded for one-day-old eggs. According to the results, a reduction in the population density of P. interpunctella in laboratory experiments is promising. However, validation studies will be necessary to fully determine the potential of ozone as a replacement for the current post harvest chemical control of P. interpunctella on either pistachio nuts or date fruits.

Abstract The Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) is a destructive polyphagous pest of many stored products. To interfere with the physiological processes, especially digestion, of the larval pest, more information on the regulatory mechanisms is needed. The brain extract from 1-day-old last instar larvae of P. interpunctella was examined. In the bioassays, the midguts were treated with the brain extract, and the carbohydrase and protease activities were measured. The brain extract showed increasing dose-dependent effects on α-amylase, α-glucosidase, β-glucosidase, α-galactosidase, β-galactosidase, and trypsin secretion in the larval midgut. The extract was further characterised and partially purified using high performance liquid chromatography (HPLC). Several peptides were determined in the brain extract regulating hydrolase activities in the larval midgut of the pest.
