Chitin is a linear polysaccharide of N-acetylglucosamine, which is highly abundant in nature and mainly produced by marine crustaceans. Chitosan is obtained by hydrolytic deacetylation. Both polysaccharides are renewable resources, simply and cost-ef

The extracellular matrix (ECM) is an acellular three-dimensional network composed of proteins, glycoproteins, proteoglycans and exopolysaccharides. It primarily serves as a structural component in the tissues and organs of plants and animals, or form

Secondary metabolites and synthetic iminosugars that structurally resemble monosaccharides are potent inhibitors of α-glucosidase activity. The enzyme is core in cleaving sucrose in phloem feeding insects and it also plays a crucial role of reducing

Emphasis is placed on the elaborate cuticular matrices in insects and crustaceans, spider and insect silks, sialomes of phytophagous and blood-feeding arthropods as well as on secretions of male and female accessory glands. Focus is placed largely on

Many arthropods and the majority of insects lay their eggs without parental care. These immobile stages of life must rely on the various eggshell layers deposited upon the developing embryo to survive biotic and abiotic stresses such as desiccation,

The reproduction of the Mediterranean fruit fly, Ceratitis capitata L. is strongly affected by reserpine. The alkaloid acts as a chemosterilant for both sexes. Treated flies appear sluggish and normal behavior related to reproduction such as mating a

The olfactory and gustatory responses of Trogoderma granarium, Tribolium castaneum and Dermestes maculatus to various even and odd numbered fatty acids were studied. C5-C8 short-chain fatty acids discouraged aggregation of Khapra beetle adults. Myris

Larvae and adults of the species Dermestes maculatus were attracted by palmitic and stearic acids and repelled by a lower homolog, caprylic acid. Lauric acid, which strongly deterred larvae, was phagostimulatory to adults. Palmitic and stearic acids
