Some Biological Aspects of Indian Meal Moth Plodia interpunctella (Hübner) (Lepidoptera Pyralidae) and its Natural

Indian meal moth, Plodia interpunctella (Hübner) life cycle was investigated the mean duration of the pre-mating, pre-oviposition, oviposition, and post-oviposition were 1.75, 2.50, 2.20, and 3.50 days, respectively. The average number of laid eggs was 138.80 eggs, and newly emerged larvae completed their growth inside the cages. The average incubation period, larva development period, pupation period, and adult longevity were 4.62, 28.50, 7.04, and 40.16 days, respectively. The duration of 1st, 2nd, 3rd, 4th, 5th, and 6th larval instars was 4.52, 4.80, 4.95, 3.90, 4.60, and 6.13 days, respectively, with a total larvae longevity of 28.90 days. Mentha longifolia L. had the largest mortality rate, 89.00 %, of the larvae and Ocimum basilicum extract, with a mortality rate of 81.00 %, while Thymus kotschyanus Bioss. was the lowest mortality rate, 55.00 %. The plant extracts treatment showed that the effective Mentha longifolia L., which gave 42.00 mortality for 48 hours at 50 % concentration and raised to 89.00% at a rate of 100% concentration, Ocinum basilicum gave 37.00 % and 81.00% after 48 hours at a rate of 50 % and 100 % concentration respectively, but the Thymus kotschyanus Boiss. Gave 41.00 % and 55.00% after 48 hours at 50 % and 100 % concentration, respectively.
