<title>Abstract</title> A two-year field study investigated the effects of varying rates fertilizer NPK 20.10.10 and timing application on vegetative growth biomass yield <italic>T. vogelii</italic> (Fish bean) at area in 2019 2020 cropping seasons. Treatments consisted three N.P.K 20.10.10. (0, 100 200 kg/ha) two periods (pre-anthesis pod commencement), giving a combination 3 x 2 = 18 treatments. Randomized Complete Block Design (RCBD) with replications was used to disperse all treatments...

Food preference of Brachytrupes membranaceus and proximate analysis the nymphal adult stages B. was carried out in Arboretum laboratory University Calabar. The nymphs were sourced from wild. Materials used as feeds included Anarcadium occidentale leaf (AOL), Arachis hypogea leaves nuts (AHL, AHN), Telfairia occidentalis (TOL), Ipomoea batatas tubers (IBL, IBT), also mixtures all vegetables, broiler mash, control. An insectarium made up 20 block compartments covering an area 15×15 m with a...

Early and late crops of flint, pop sweet maize (Zea mays L.) were sown in field plots laid randomized complete block design at the Teaching Research Farm 2004. Stem borer infestation damage assessed both treated with 1.5 kg carbofuran/ha those not for stem control. The types, as subplot treatments, carbofuran application vs no application, main plot replicated four times. Borer was quantified percentage dead-heart, bored stems, lodged internodes, numbers larvae/stem cavities. parameters...

A survey work on the benefits of entomophagous insects was carried out in four Local Government Areas Central Zone Cross River State, Nigeria to assess most preferred and consumed edible insect species. Three communities were selected from each Area. hundred twenty (320) structured questionnaires administered sampling population. The data processed subjected statistical analysis such as descriptive percentages well variance. result showed that (bug, beetle, termite, bee, caterpillar,...

Abstract Background Coptotermes sjostedti Holmgren (Isoptera:Rhinotermitidae) is one of the major termite species found infesting woods and other plant materials in Africa. Bioassays were carried out at Arboretum Department Forestry Wildlife Resources Management, University Calabar, Nigeria to investigate effect oils from kernel Jatropha curcas L. Azadirachta indica A. Juss against African subterranean ( Holmgren). Treatments comprised Solignum (a synthetic termiticide, serving as positive...
