Wool, as a keratin, is a highly cross-linked, insoluble proteinaceous fiber, and few animals have developed the specialized digestive systems that aUow them to derive nutrition from the potential protein resource. In nature, these few keratin-digesting animals, principally the larvae of clothes moths and carpet beetles, perform a useful function in scavenging the keratinous parts of dead animals and animal debris (fur, skin, beak, claw, feathers) that ate inaccessible to other animals. It is only when these keratin-digesting animals attack processed wool goods that they are classified as pests. Very often they enter domestic or industrial huildings from natural habitats such as birds nests.

Dermestids. The two most common invaders are the carpet beetle and the drugstore beetle or cigaret beetle. The latter, although not exactly identical species, are comparable in their habitat and habits. They are all likely to fly into the plant.

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]. 

Virgin females of the furniture carpet beetle, Anthrenus flavipes, produce (Z)-3-decenoic acid as a sex pheromone 107 [207]. In contrast, the female-produced sex pheromone of the varied carpet beetle Anthrenus verbasci is a two component mixture of (Z)-5-undecenoic acid 108 and its (E)-isomer [208]. Recent investigations showed the presence of additional electrophysiologically active components, however, no behaviour tests have been carried out [209]. 

The sex pheromone of the Guernsey carpet beetle, Anthrenus sarnicus, contains 1-decanol and its butyrate 109 in almost equal amounts [210].

In order to evaluate the results of the operations, insects of several species were caged in the buildings that were to be fogged, both in the open and in places of difficult access, such as in cupboards and behind baseboards. In the first series of tests, the insects included bedbugs, cockroaches, houseflies, clusterflies, clothes moths, and carpet beetles. 

The tests in the second series included buildings fogged with the oil Sovacide 544C alone, and it was found to possess significant insecticidal action at stations where a high concentration of fog occurred. This was evident particularly with houseflies, German cockroaches, mosquitoes of the genus Aedes, and furniture carpet beetles. 

As with human disease vectors, so DDT succeeded initially with some of the major agricultural pests. By the early 1970s over 4 billion pounds of the insecticide had been used--approximately 80j> of it on agricultural crops. It was also in wide use for pest control in home flower and vegetable gardens, and domestically as protection against moths and carpet beetles. 

Dermestidae. The sex pheromones of the so called carpet beetles appear to be generally identified with unsaturated normal or monomethyl-substituted alcohols, acids, or esters. Females of the black carpet beetle, Attagenus megatoma, utilize... 

E,Z)-3,5-tetradecadienoic acid as a sex attractant (55). The sexual releaser emitted by females of the furniture carpet beetle, Anthrenus flavipes, has been identified as (Zj-3-decenoic acid (56). The (Z)-isomer is about 20X more active than the (E)-isomer. 

Typical physical and chemical properties of commercial modacrylic fibers have been published (125). Modacrylics are not affected by bleaches in the concentrations used for spot and stain removal (31). They are immune to attack by rot, mildew, bacteria, and insects such as moths and carpet beetles (125). Fungi may grow in dirt in an unlaundered Dynel fabric, but washing out the dirt removes the mildew with no effect on the fabric. 

The major constituent in the extract of madder, Rubia tinctorum (Rubiaceae), was identified as lucidin-3-O-primeveroside (342), a commonly used food pigment. It exhibited antifeedant activity against the carpet beetle, Attagenus japonicus 50 This opens the window for using dyes from either R. akane or R. tinctorum to protect textile against these textile pests. 

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. 

Use Ovicide, effective against moths, furniture and carpet beetles, cockroaches, and body hce. 

In another study, 0.25%- pynelhrins + 1. 0% PBO applied from domestic aerosol cans protected woollen cloth from attack by webbing clothes moths for up to 27 months and by carpet beetles for shorter periods when the treated articles were stored in the dark (Bry et vl., 1477). 

A wool-like fiber, sp gr 1.18. Softens at about 175". Flammability similar to cotton and viscose, fnsol in acetone, methylene chloride. Good resistance to sunlight, clothes-moth and carpet-beetle attack, and mildew moderate resistance to 10% H2S04 at 100" for hrs, and to 0.5% caustic soda at 43 for 7 days. Shrinks about 1% when immersed in boiling water for 3 minutes. Difficult to dye. Relatively resistant to pilling.
