Peridroma saucia

Even more extraordinary, the authors presented evidence that the attractant mixture produced may vary with time both within and between individuals, suggesting that the spiders have some degree of control over the composition of the blend. This would explain why at least 19 different moth species are captured by M. cornigera, even when compounds that attract one species are known to be inhibitory to a second prey species. For example, the noctuid moth Peridroma saucia is attracted to blends of 16 and 18, but attraction is inhibited by 17. This type of situation is well documented with lepidopteran sex pheromones and is one of the mechanisms that allows related species to share some pheromone components while still maintaining species-specific attractant blends (Roelofs, 1995). Thus, M. cornigera must...

Petuniolide C (XVIII) was available in reasonable amounts, and we submitted samples of the compound elsewhere for tests upon other insects. The tobacco horn-worm (M. sexto) was susceptible to this compound in artificial diets (as might have been expected from early observations of larvae on the plant), with only 50% survival of animals to the prepupal stage at a dosage of 20 ppm (J. Oliver, personal communication). Another caterpillar, the variegated cutworm (Peridroma saucia Hubner), was...

Some essential oils develop a combined activity on the insects, for example, EOs of Ocimum spp. exhibited both a repellent and a larvicidal action [45]. Acorus calamus EO and its active ingredients, asarone and its analogues, were both antifeedant and potent growth inhibitors to the variegated cutworm Peridroma saucia (Lepidoptera Noctuidae) [46]. It has also been shown that some essential oils exert quite opposite effects on different insect species. As an example, the tansy (Tanacetum vulgare L.) EOs impacted in different ways the following three beetles it was attractive and paralyzing for Rhizoperta dominica, repulsive for Tribolium confusum, and toxic for Sitophilus americana [47].

In two bioassays, semiochemicals were applied first to the bottom and sides of glass scintillation vials, while in the second, an equivalent quantity was applied to the inside of the top of the vial. In both cases, the semiochemicals were applied in solvent, then the solvent was allowed to evaporate. Surfaces or lids of control vials were treated with solvent only. After the solvent had evaporated, five neonate larvae of the variegated cutworm, Peridroma saucia, were introduced into each vial for a 4-h exposure period. After exposure to the test chemicals, larvae were transferred to artificial diet, and their survival was assessed 24 h later. Because larvae could not climb the slippery surfaces of the glass vials and contact the...
