This laboratory study aimed to evaluate the efficiency of two biological agents Beauveria bassiana (Bals) and Bacillus thuringiensis (Kursaki) and four chemical pesticides Levo 2.4 SL, Aster 20 SL, Difuse 450 SC, and Matrixine Plus EC on four important main pests that infect tomato plants. The pests studied were whitefly Bemisia tabaci (Hemiptera: Aleyrodidae), Meyrick Tuta absoluta (Lepidoptera: Gelechiidae), Sulzer Myzus persicae (Hemiptera: Aphididae) and Koch Tetranychus urticae (Acari: Tetraanychidae). The results show that the pesticide Matrixine Plus recorded the highest average of mortality of both larval and adult stages of all four pests. The average of mortality for adults and larvae of whitefly were 96.67% and 86.67% respectively. The average of mortality for adults and larvae of Meyrick was 93.33% for both stages, while the percentages for adults and larvae of Sulzer and Kotch were 96.67% respectively after seven days of exposure. The lowest averages of mortality were recorded for Antario on whitefly adults and for Difuse on whitefly (both (16.67%). Difuse caused the lowest average of mortality (26.67%) on Meyrick adults, whereas Antario caused the lowest average of mortality of 20% on Meyrick larvae. The results show also that Antario caused the lowest average of mortality of 23.33% on adults and 16.67% on larvae. Similarly, Difuse was recorded the lowest average of 20% on adults while Antario caused the lowest average of mortality of 26.67% on larvae after one day of treatment.

The quality of Heteroclarias with increased storage time using Quality Index Method (QIM) was evaluated. 140 live samples of Heteroclarias (average weight 230 + 7g) were used for the study. QIM was used to evaluate the key parameters in fish deterioration, twenty semi-trained assessors was used for the sensory evaluation. Data obtained were subjected to appropriate statistical tools using SPSS 16.0 version. Quality Index (QI) of Heteroclarias increases with increased post slaughter time when the fish was left at ambient temperatures (27 + 3°C) indicating decrease in fish quality with time. High correlation of (r=0.993) with a high coefficient of determination (R2=0.986) was obtained indicating that 98.6% of the variation in post slaughter time was explained by quality attributes; the regression equation was significant F(9, 130)=1080 (p<0.0001) indicating that it could be used for prediction and estimation of fish quality, the QI used in this study is therefore recommended to be used by relevant agencies for predicting fish quality.
Practical Applications :Fish is highly perishable despite its nutritional value, consumers becoming increasingly interested in the quality of fish they consume and the physical attributes of the fish is very vital for on the spot assessment of fish quality. This study provide quality index that could be used for prediction and estimation of fish quality using sensory evaluation.

The study was carried out using 405 chicks with a one-day-old, type Rose 308. The birds were randomly distributed to nine experimental treatments, with three replicates per treatment (15 birds/replicate). The birds were fed ad libitum during the 42-day trial period, 9 diets were used for study in the starter and 9 diets in the finisher period, as protein source used the Vetch 12.5% and 25% as an alternative to soybean meal, Vetch was treated by soaking in water or acetic acid (1% concentration) or by adding activated charcoal 50 gm / 100 kg diets. The results of the 21-day starter level showed a significant difference (P < 0.05) for live body weight, weight gain, consumed feed, and feed conversion ratio between control treatment and Vetch treatments 12.5% and 25% soaked water, acid and activated charcoal. While there were no significant differences in Mortality% in the period 21 days, in the finisher period (22-42 days), the results showed significant differences (P <0.05) between control treatment, Vetch seed and Vetch seeds treatments for body weight, weight gain, consumed feed and feed conversion ratio, Also, there was no significant difference between treatments for mortality% in this period.
