Moulting of Insects

The significance of moulting in Ecdysozoan evolution.

Three major bilaterian clades first appear in the Early Cambrian fossil record: Deuterostomia, Lophotrochozoa, and Ecdysozoa. The taxa placed in Ecdysozoa are characterized by a moulting habit, unknown in the other major clades. The origin and consequences of moulting are of fundamental importance to the history of the ecdysozoan clade, chiefly because moulting precludes motile ectodermal cilia...

The role of moulting in parasite defence.

Parasitic infections consist of a succession of steps during which hosts and parasites interact in specific manners. At each step, hosts can use diverse defence mechanisms to counteract the parasite's attempts to invade and exploit them. Of these steps, the penetration of parasites into the host is a key step for a successful infection and the epithelium is the first line of host defence. The s...

Diversity and Abundance of Insects in Wukari, Taraba State, Nigeria

A field survey was conducted in Wukari, Taraba State to assess the diversity and abundance of insect species in selected habitats (residential, open field made up of grassland and an agroecosystem). Sampling were done biweekly using light, pitfall and yellow pan traps set in 3 replicates, 30 m apart. Insects recovered were wet preserved in 70% ethanol except butterflies and moths. Representativ...

Induced Moulting in Layers – a Review

Poultry industry is playing the biggest role in the industries of the developing countries with respect to the capital generated by this industry as well as the fulfillment of the nutritional requirements. The improvement in the production potential of the existing layer population is more imperative as compared to the size of the flock. In this aspect induced moulting is a valuable as well as ...
