Isolation Mechanisms

Interspecific courtship was observed between the Indian meal moth, Plodia interpunctella, and the almond moth, Cadra cautella. Successful cross-mating did not occur, however, because of the following isolation mechanisms: (1) incompatible courtship behavior, (2) male sex pheromone as a species recognition signal, (3) inhibition of males to female sex pheromone stimulation, and (4) mechanical or physiological barriers to insemination.Male Indian meal moths were strongly excited by calling almond moth females and courted them vigorously. However, because the courtship behavior of this combination was incompatible, copulation did not occur. Occasionally courtship continued to a later stage in the sequence but then the female rejected the male apparently because he releases an inappropriate aphrodisiac from his scent scales.In the reciprocal cross, fully two-thirds of the almond moth males failed to be sufficiently excited by Indian meal moth females to court them. Most of these males were inhibited, as indicated by their subsequent lack of response to pheromone extracts from their own female. Those males which were excited by Indian meal moth females courted them successfully and copulated, but insemination apparently did not occur. In a few cases the females rejected the males, as in the reverse cross.

COMPATIBILITY OF XYLOCORIS FLAVIPES (HEMIPTERA: ANTHOCORLDAE) AND VENTURIA CANESCENS (HYMENOPTERA: ICHNEUMONIDAE) FOR SUPPRESSION OF THE ALMOND MOTH, CADRA CAUTELLA (LEPIDOPTERA: PYRALIDAE)

The predaceous bug Xylocoris flavipes (Reuter) was combined with the parasitic wasp Venturia canescens Gravenhorst to assess their compatibility in suppressing the almond moth, Cadra cautella (Walker). Each natural enemy was applied at 10, 20, 30, 40 and 50 insects for each ca. 1000 C. cautella. Significantly greater (P < .0001) suppression of C. cautella was obtained by the combination of X. flavipes and V. canescens at all levels. This demonstrated that the combination of X. flavipes and V. canescens is likely to enhance suppression of C. cautella in field applictions.

Abstract Thirty-nine selected peanut (Arachis hypogaea L.) genotypes from a diverse germplasm collection with known resistance and susceptibility to preharvest insects were tested in the laboratory for postharvest resistance to the Indian meal moth, Plodia interpunctella (Hubner), and the almond moth Cadra cautella (Walker). After the initial test the number of genotypes was reduced to 20 to reduce duplication of pedigree and omit some of the genotypes with intermediate resistance. Additional data were collected from the 20 genotypes on ovipositional preference and larval establishment on shelled and unshelled (farmers stock) peanuts. Genotypes with resistance to moth species included NC 6, GP-NC 343 × NC 5, PI 467307, NC 7 × NC 10247, GP-NC 343 × NC 17367 and breeding line 10-P10-B1-B1-B1-B1-B2. Resistance to preharvest and postharvest insect complexes suggest some common chemicals may be present in the green crop and the harvested seed that elicit ovipositional response.
