Abstract: French bean, (Phaseolus vulgaris) L. is key commodity for export in Kenya. The value of export increased from 4,466.7 Kenya Shillings in 2002 to 4,466.7 Kenya Shillings in 2006. Production of French beans is constrained by many factors including pests, lack of capital and credit facilities, fluctuation in demand, and difficult accessibility to the market, and improper grading. The major arthropod insect pests of French beans include bean stem maggots, flower thrips, pollen beetles,...
Abstract: Fruit flies (Diptera: Tephritidae) represent the major constraint for fruit production worldwide, where they cause direct and indirect damages. The species B. dorsalis and C. cosyra are the main species attacking mango in Mozambique. For implementation of control measures, knowledge of population dynamics is essential. However, there is no record of spatio-temporal dynamics studies for orchard level and evaluation of the dynamics of B. dorsalis and C. cosyra, together, in Mozambique.
Abstract: Plant parasitic nematodes (PPN) are biotic constraints to crop production worldwide resulting in significant yield losses. Management of these nematodes has primarily depended on chemical nematicides; but due to the increased pressure for more economic and environmentally friendly strategies, alternative methods like organic and conventional amendments, have been considered. To test the efficacy of conventional and farmer practice systems against organic farming in the suppression ...
ABSTRACT Liriomyza huidobrensis (Blanchard), Liriomyza sativae (Blanchard) and Liriomyza trifolii (Burgess) are multivoltine flies, which are highly polyphagous, prolific and invasive. They are currently important pests in areas where horticultural crops are grown in Kenya. Both the adult flies and larvae cause considerable damage to crops. Infestation results to reduced photosynthetic potential of plants, which translates to reduction of the expected yield and loss of the aesthetic value. I...
