Terminalia ivorensis ( Idigbo or black afara) is a useful hard wood of the humid tropics of Africa. It is currently under threat due to over exploitation as well as poor regeneration. Qualitative studies was carried out in a mixed population of T. ivorensis and some fruit and medicinal trees at the Forestry and Environment Arboretum, Rivers State University of Science and Technology (RSUST) . Data presentation was done visually and pictorially. It was observed that the larvae of Epicerura pulverulenta with a Diameter of 1.5cm and Length of 7.1cm. The larvae are aggressive defoliator of T.ivorensis. Defoliation of entire plant stand occurred less than 7days. It was also noticed that defoliation was selective as other plants were not affected.This is the first report on E. pulverulenta invasion of T.ivorensis in Rivers State and Nigeria in general. Conclusively, the larvae of E.pulverulenta are a major threat to the growth and establishment of T. ivorensis.

Entomology and Applied Science Letters is an international peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. Papers on non-insect groups are no longer accepted. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Call for Papers
Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research. This has become the need felt in scientific research due to the emphasis on intra-, inter-, and multi-disciplinary approach.
