TL;DR: The principal component of the sex attractant of the black carpet beetle Attagenus megatoma (Fabricius) is trans-3, cis-5-tetradecadienoic acid.
Abstract: The principal component of the sex attractant of the black carpet beetle Attagenus megatoma (Fabricius) is trans-3, cis-5-tetradecadienoic acid.
TL;DR: A volatile substance was obtained from the unmated female adult of the black carpet beetle, Attagenus piceus (Olivier), Trogoderma inclusum LeConte; and T. glabrum (Herbst) that influenced the behavior of the respective males.
Abstract: A volatile substance was obtained from the unmated female adult of the black carpet beetle, Attagenus piceus (Olivier); Trogoderma inclusum LeConte; and T. glabrum (Herbst) that influenced the behavior of the respective males.
The volatile chemical or chemicals were collected by allowing the virgin females to walk on absorbent-paper disce or by washing with ether the filter paper and glass jars that held the virgin females. The substance was also filtered from an air stream that had passed through a flask containing virgin females.
TL;DR: A key for the identification of adult and mature larvae of nine species of Dermestidae (Coleoptera) found associated with the Indian silkworm industry is given.
TL;DR: The excreta of clothes moth larvae (Tineola) bred on a· standard undyed woollen fabric, the black carpet beetle (Attagenus) living on wool, and the potato moth feeding on potato tubers, have been examined.
Abstract: The excreta of clothes moth larvae (Tineola) bred on a· standard undyed woollen fabric, the black carpet beetle (Attagenus) living on wool, and the potato moth (Gnorimoschema) feeding on potato tubers, have been examined. Water-soluble nitrogen constitutes most of the total nitrogen in both Tineola and Attagenus excreta. The fraction of this water-soluble nitrogen ontributed by uric acid or its salts is high in Tineola, but considerably lower in Attagenus. Up to 3 per cent. urea and an appreciable quantity of ammonia are also present.
TL;DR: The rates of pupation of Attagenus elongatulus Casey larvae were reduced by increased larval crowding and artificial selection reduced the crowding effects and shortened the minimum life cycle.
