Laboratory studies of the biology of Helopeltis schoutedeni Reuter (Hemiptera: Miridae), a major sucking pest of cashew (Anacardium occidentale Linn.)
Cashew (Anacardium occidentale Linn.) has become a very important non-traditional tree crop in Ghana. Several insect pests, however, have been recorded on cashew and prominent among which is the cashew mosquito, Helopeltis schoutedeni Reuter (Hemiptera: Miridae). The biology of H. schoutedeni was studied in the laboratory at 24.9 to 33oC and 72.4 to 88.5% Relative humidity (R.H.). Females pre-dominated males in the...

Effect of season and farming system on the quantity and nutritional quality of scavengeable feed resources and performance of village poultry in central Tanzania
A 2 x 2 factorial study was conducted to assess the effect of season and farming system on the quantity and nutritional quality of scavengeable feed resources and the performance of village poultry in central Tanzania. A total of 648 scavenging chickens purchased from farmers were slaughtered and the crop contents were subjected to physical and chemical analysis. The mean fresh weights of the crop contents were higher...

Assessment of Bos taurus embryos comparing stereoscopic microscopy and transmission electron microscopy
Transmission electronic microscopy was used to test the efficiency of the classification criteria for Bos taurus embryos using conventional stereoscopic microscopy, since the criteria used for Bos indicus has proved inaccurate with the latter method. Embryos were collected from Holstein heifers 7 days after artificial insemination and classified according to the criteria established by the...

A comparative morphometric analysis of the stomach in rat Rattus norvegicus, bat Eidolon helvum and pangolin Manis tricuspis
The difference in the feeding habits of these three mammals necessitated this study, (pangolin being insectivorous, bat frugivorous and rat omnivorous). This study compared the macro and micro-morphometric adaptations adopted by the stomach of the three mammals to cope with their feeding habits. The study was carried out using sixteen rats, sixteen bats and eight pangolin of both sexes randomly divided into two equal...

Effect of replacement of cocoa bean shell for maize on growth, carcass characteristics and organoleptic properties of growing snail (Archachatina marginata)
In a completely randomized design, a total of 120 growing snails of mean weight 156.69 ± 3.4 g were used to investigate the effect of partial replacement of maize with cocoa bean shell (CBS) for growing snail for 20 weeks. There were five treatments and three replicates of 8 snails each. The diets contained 0.0, 2.5, 5.0, 7.5 and 10.0% CBS in partial replacement of maize and designated T1, T2, T3, T4and...

Impact of Flufenoxuron, an IGR pesticide on Gallus domesticus embryonic development in ovo
The struggle against the agricultural devastating is increased in few last years and many products are created to kill the harmful insects and bug, without controlling their effect on ecosystem and non-target animals. In present work, we try to investigate the effects of the Flufenoxuron, which is an Insect growth Regulator (IGR) on embryonic development of hen’s eggs as a non-target organism...
