Almond Moth

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.

Three factors contributing to fitness of a species (fertility, fecundity, and development time) were measured in the susceptible Savlab strain and the > 100-fold malathion-resistant Statesboro strain of the Indianmeal moth, Plodia interpunctella (Hübner). Both fertility (percent egg hatch) and fecundity (eggs/female) were significantly lower in the resistant strain. Percent egg hatch in the two strains was 96.2% and 73.1% for Savlab and Statesboro respectively. Fecundity was 444 eggs/female for Savlab and 321 eggs/female for Statesboro. Development time did not differ significantly (24.2 ± 0.3 and 23.6 ± 0.2 days for 50% emergence). There was no evidence that these differences arose from non-lethal effects caused by malathion treatment to maintain resistance in the Statesboro strain. The differences, while associated with malathion resistance, cannot be unequivocally attributed to the presence of the resistance gene. When the intrinsic rate of increase (rm) was calculated using an iterative computer program, Statesboro had a significantly lower rate (0.1734 ± 0.0016) than did Savlab (0.2048 ± 0.0014). Similar measurements were performed with progeny from reciprocal F1 crosses. While some parameter's values were closer to Statesboro or Savlab an apparent mating incompatibility suggests that using the data from F1 crosses is premature until this question is resolved.
