The female produced sex pheromone of the black carpet beetle, Attagenus unicolor (formerly called A. megatoma or A. piceus) has been identified as early as 1967 to be (3 ,5Z)-3,5-tetradecadienoic acid, megatomoic acid 106 [204,205] (Scheme 12). The (3Z)-isomer of megatomoic acid was found to be the major male attracting component in the female produced pheromone of A. brunneus (formerly A. elongatulus) [206].

Pheromones of insect species in the order Coleoptera are characterized by considerable structural diversity. Unlike the lepidopterous sex pheromones, which are nearly all tatty acid derivatives, coleopterous sex pheromone structures range in complexity from the relatively simple 3,5-tetradecadienoic acid of the black carpet beetle to the tricyclic terpenoid, lineatin, of the striped ambrosia beetle. While the sex pheromones of many beetles consist of mixtures of compounds that act synergistically to elicit a behavioral response, other Coleoptera species appear to use only a single compound for chemical communication between the sexes. In the latter case the compound usually has at least one chiral center and chirality plays a major role in determining pheromone specificity. 

Further tests in the laboratory showed that 24,055 was effective when applied to surfaces other than growing plants. Wool impregnated with the compound was not attacked by the larvae of the black carpet beetle, and lesser grain borers would not penetrate treated paper bags containing grain.

The principal insects that attack wool are the common clothes moth (7)i-neola bisselliella), the case-bearing clothes moths Tinea metonella, T. dubiella, T translucens, and T. pellionella), the brown house moth Hofmannophila pseu-dospretella), the variegated carpet beetle Anthrenus verbasci), the black carpet beetle (Attagenus piceus), and a few others. The taxonomy of the Tineid species has been comprehensively reviewed (143). These insects have difierent temperature sensitivities and tend to be found in different climates. Studies in Australia have shown that the native Tineids are rarely involved in domestic infestations. The introduced species, such as T. translucens, are the major textile pests and these are often associated with the nests of introduced urban bird species such as sparrows and swallows (144), while T. bisselliella is widely distributed and is common in domestic infestations.

Females of the black carpet beetle, Attagenus megatoma, produce the sex pheromone ( , Z)-3,5-tetradecadienoic acid 301). An important related species, A. elongatulus, has also been shown to produce a sex pheromone 302) and a major attracting component has been identified as (Z,Z)-3,5-tetradecadienoic acid 303).
