    Opis:
    Plant communities which form orchard edges are a vital element of ecological infrastructure enriching these agrocenoses. The research was conducted in an orchard environment made up of apple orchards and their edges in the form of agricultural cultivations, tree clumps and a road lined with trees and shrubberies. The study aim was to determine the impact of the orchard edge plant diversity onto the number and abundance of Ichneumonidae subfamilies in the orchards. The study showed that orchard environments made up of an apple orchard and edge plants of various species create better living conditions for Ichneumonidae parasitoids than the environment of an orchard and neighbouring agricultural cultivations. The diversity of orchard edge plants positively influences the abundance of the Ichneumonidae subfamilies rather than the number of subfamilies in the orchard. In the orchard habitat the following dominant subfamilies were found: Campopleginae, Cryptinae, Orthocentrinae and Pimplinae. These entomophages may control the abundance of pests infesting orchards.

    Opis:
    This study investigated insect pest infestation of maize, millet, sorghum, rice and wheat grains traded in the three main markets namely Monday, Baga-Road and Custom-Park markets in Maiduguri, Borno state, Nigeria. Sampling lasted from January to June 2012. Samples per grain type, each weighing one kilogram, were obtained every two weeks from ten randomly selected traders per market. Each sample was sieved in the laboratory to recover all adult insects present, both at sampling and also after one month stay (laid out in a completely randomized design). In each market, Sitophilus zeamais Motschulsky and Rhyzopertha dominica (F.) followed by Tribolium castaneum Herbst, Sitophilus oryzae (Linnaeus), Trogoderma granarium (Everts) or Cryptolestes sp. were the insect pests commonly found attacking more (between two to five) grain types. Observed highest and lowest mean insect numbers were respectively by S. zeamais in maize grains (12.13 individuals in Monday market) and T. granarium in wheat grains (0.13 individuals in Baga-Road market). Results unveil that among three markets, higher mean total numbers of insects were present in maize, rice or wheat (18-33). For all grain types, the mean numbers of damaged grains were significantly higher in Monday (53-357) and Custom-Park (46-302) than in Baga-Road (17-109) markets. Furthermore, the mean total number of damaged grains across markets was significantly higher maize, followed by rice and wheat (55-231) than in other grain types (37-41). The implications of all these results on insect infestation of different cereal grain types sold in these markets are discussed.

    Opis:
    This study assessed the insect pest infestation of tomato during 2011 and 2012 in three localities namely Bula Kuliye, Kajeri and Soye of Bama Local Government Area, Borno State, Nigeria. Fifty plants were randomly checked per farmers’ field for insect pest recovery and count. Sampling was carried out in five to nine farmers’ fields per locality. With 38-52 %, 9-62 %, 13-39 % and 5-9 % species composition respectively across localities, Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) followed by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) were more predominant insect pests of tomato in these localities over Tetranychus sp. (Acari: Tetranichidae) and Spodoptera litoralis (Boisd.) (Lepidoptera: Noctuidae). Total proportion of infested tomato plants per farmers’ field ranged from 19-36 %, and was significantly higher in Bula Kuliye and Kajeri than in Soye. Total number of insect pests per plant/leave and bored fruits per farmers’ field fell between 2-5 and 21-35, and likewise, was higher in Bula Kuliye and Kajeri than in Soye. Although tomato plant infestation and fruit damage were found to be moderate or high in these localities, future studies on the bionomics or population dynamics of these insects remain essential for establishing their economic status.
