Control of Periplaneta Americana using Boric Acid & Neem Tree leaflets powder
No full text10 pages (59-68) SJS 6(1) 2014The American cockroach, Periplaneta americana is the largest of house-infesting cockroaches and causes’ public health problems making it an strategic target for control. Different concentrations of Boric acid and neem tree leaflets (old of young developmental stage, OY) powders were used in this study. The powders were incorporated into food mixtures designed here to produce baits and the lethal dose (LD50) was calculated for each treatment. For both treatments, the toxicity was found to relate with the amount ingested by a cockroach (mg/ cockroach). Increased concentrations of Boric acid were found toxic to P. americana and mortality percentage increased in a positive correlation with concentration. LD50 was 2.0889±0.00136 g. On the other hand, two effects were observed for neem OY leaflets: a) a toxic effect and increase in mortality for concentrations up to 3.75g with LD50 =4.345±0.07694 g; and b) a repellent effect as well as a decrease of mortality for baits with concentrations of 5g-6.667g

No full text7 pages (34-40) SJS 6(1) 2014The egg, larval stages (I, II, and III) and the adult male and female were examined under a dissecting microscope. For each one of the above stages the body length, colour and other morphological characteristics were investigated. The anterior and the posterior spiracles of the three larval stages were dissected out and examined under a phase contrast microscope
The effect of ethanolic leaves extract of Solenostemma argel on blood electrolytes and biochemical constituents of albino rats
No full text6 pages (48-53) SJS 6(1) 2014The ethanolic leaves extract of S. argel was studied for its effect on the blood electrolytes and biochemical constituents of albino rats. The animals (n= 12, average BW= 240 g) were divided into two groups of six each: one to act as the experimental group (EG) and the other as the control group (CG). The result Revealed that K, Ca and P for electrolytes and creatinine, urea, aspartate aminotransferase (AST) and alkaline phosphatase (ALP) for biochemical constituents were found significantly higher (P < 0.05) in experimental group when compared with the control group. In the meantime, total protein, albumin, total bilirubin, and alanine aminotransferase (ALT) for biochemical constituents, and Na and Fe for electrolytes did not differ significantly from those of the control group (P > 0.05). The findings of this study suggested that the dose 600 mg of extract /Kg BW was more likely to have adverse effect on liver and kidneys of albino rats
