The monograph is presented in four parts. The first part is devoted to the experimental and theoretical substantiation of the criteria for safety and quality assessment of goat's milk. Parameters of subclinical mastitis in goats, comparison of methods efficiency for determination of somatic cell count in goat milk, monitoring studies of goat's and cow's milk in France and Ukraine, effect of exogenous and endogenous factors on the quality and safety of goat milk are described. The second and third parts are devoted to Coleoptera pests of stored food supplies and field crops. The forth part includes characteristics of Poaceae family members in the steppe zone of Ukraine as the main objects of farm animals feeding. Ecological characteristics of the species according to the Belgard Ekomorph System and their geographical analysis were presented. Sozological and feeding value of the species were described.

Environmental and human health problems associated with the use of synthetic pesticides have prompted the demand for non-polluting, biologically specific insecticides. The current study assessed the losses caused by Tribolium confusum and its control by diatomaceous earth and the effect on Aspergillus flavus spore dispersal during storage of groundnuts. When losses due to Tribolium confusum were assessed over a period of 60 days, it was found that an increase in insect population in stored groundnuts resulted in increased weight loss of stored groundnuts. The true weight loss due to insect feeding was 0.60 g per 400 g of stored groundnuts. When diatomaceous earth (DE) was applied to groundnuts followed by the introduction of insects in a compartment (A), increased mortality of insects with increased diatomaceous earth concentration was observed. For a concentration range of 0-2.5 g DE/kg groundnut, 2.5 g/kg treatment was the most effective (only 5 surviving T. confusum adults out of 50 were recovered in samples treated with 2.5 g/kg compared to 38 adults in the control samples). Larval emergence from groundnuts treated with DE also declined with increased diatomaceous earth concentration. When groundnuts were inoculated with A. flavus spores, followed by DE application and T. confusum introduction into compartment A, the transfer of spores between inoculated groundnut samples in compartment A and uninoculated samples in compartment B was reduced. The mean A. flavus spore concentration recovered from initially sterile compartment B was1.08x10 3 ; while it was 45 in the control and in samples treated with 2.5 g/kg dosage respectively. There was a significant difference in the mean numbers of spores recovered from groundnuts in different compartments (A, B) (H = 13.99, df = 4 and P = 0.007). Thus, from this study, losses due to T. confusum on groundnuts and fungal spore transfer in storage by this insect can be minimized by the application of diatomaceous earth (Protect-It™) to stored groundnuts.

Laboratory experiments were conducted to assess the effectiveness of black pepper, Piper guineense (Thonn.) as a protectant of melon, Citrullus vulgaris Schard against fourth instar larvae of the Merchant beetle, Oryzaephilus mercator (Fauvel) in each of two environments (aerated and airtight). In the aerated environment, the means of O. mercator emergence, were 19.84 +0.46, 9.49 + 0.90, 6.40 + 0.34, 3.46 + 1.25, 1.49 + 0.90, 0.00 + 0.00, and 0.00 +0.00, for the control, 0.25g, 0.5g, 0.75g, 1g, 2g, and 3g pepper 120g melon, respectively, while the corresponding means in the airtight environment were 18.42 + 1.06, 8.86 ±3.88, 4.93 ± 0.26, 2.78 ± 2.82, 1.09 ± 0.58, 0.00 ± 0.00, and 0.00 ±0.00. Student-Newman-Keuls Procedure indicated that in both environments, all the six rates of black pepper significantly reduced O. mercator emergence compared with the control treatment. Total control was obtained at 2g pepper/20g melon and 3g pepper/20g melon treatments in both environments. The LC50 and LC90 of black pepper against O. mercator were 0.27g and 0.9~g pepper 120g melon, respectively, in the aerated environment and 0.30g and 0.93g pepper/20g melon, respectively, in the airtight environment. Thus the black pepper, which is readily available throughout the year in the West African region, relatively cheap, non-toxic, and amenable to safe handling by illiterate peasant farmers, provides a good alternative to synthetic insecticides in the control of O. mercator since resistance to most of these chemicals had been reported.
