The Role of Insects as Potential Vectors of Cassava and Cowpea Bacterial Blight in West Africa

Abstract: Xanthomonas campestris pv.manihotis (Bondar, 1912) (Xcm) and Xanthomonas campestris pv. vignicola (Burkholder, 1944) (Dye, 1978) (Xcv) are both worldwide important pathogens, causing bacterial blight diseases of cassava and cowpea, respectively. The presence of the pathogens in/on the variegated grasshopper Zonocerus variegatus (L.) (Orth.: Acrididae), an occassionally important pest of cassava and cowpea in West Africa, was demosntrated. X. campestris pv. manihotis and X. campestr...

The influence of different Host plants on the green Leafhopper Empoasca Decipiens Poali (Homoptera:Cicadellidae) and its Parasitoid Anagrus Atomus (L) Halliday (Hymenoptera:Mymaridae)

Abstract: The green leafhopper Empoasca decipiens Paoli (Homoptera: Cicadellidae) has recently become a serious pest of vegetables and ornamentals grown under field conditions and in greenhouses in many European countries. The egg parasitoid Anagrus atomus L. (Hymenoptera: Mymaridae) is a promising biological control agent of E. decipens. The objectives of this research were to assess the influence of host plants on the leafhopper and its parasitoid. Therefore, host plant acceptability ans s...

Economic Impact of Integrated Pest Management Technology for Control of Mango Fruit Flies in Embu County, Kenya

Abstract: Mango is the third most important fruit in Kenya in terms of area and total production. nutritionally, mango fruit is important for vitamins and mineral provision in the dail diet of Kenyans. as an export.....(continue from the attached PDF)

Soil Nematode Communities under Organic and Conventional Farming Systems in Chuka, Tharaka Nithi County, Kenya

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 ...

Ex- ante Economic impact Assessment of Integrated Citrus Pests and Diseases Management Interventions in Selected Counties, Kenya

Abstract: In Kenya, citrus industry has been on the decline due to pests and diseases specifically African citrus triozid (ACT), false codling moth (FCM) pests and Huánglóngbìng (HLB) disease.Management of ACT, HLB and FCM is currently based on application of pesticides. Use of pesticides is associated with increased environmental risks, substantial increase in production costs and pesticide resistance. Furthermore, exports are limited due to non-compliance to maximum residue levels (MRLs...

Assessment of Health and Environment Effects of Mango Integrated Fruit fly Management Strategy in Meru County

Abstract: Mango is among the three most imperative crops in Kenya in terms production and crop area. However, mango production is limited by a number of issues, among which pests and fungal disease infestation are major. Among the pests, mango fruit fly present a real challenge to producers due to losses incurred at the farm level. Majority of the farmers have decided to use of pesticides which have negative impacts on health and environment. To promote sustainable and environmentally friend...

Effect of farmer’s knowledge and attitudes on management of the tomato spotted wilt virus in Sironko District

Abstract: Over 80 percent of the population in Uganda live in rural areas and is mainly engaged in subsistence agriculture for their livelihood. Crop farming especially tomato growing is an activity that communities rely on for their livelihoods as well as a source of income for many households in Uganda. Tomatoes contribute to the household income, food and nutritional security yet they are affected by pests and diseases due to poor agronomic practices, lack of improved varieties for high y...

Perfomance of Exotic Chicken fed insect-based diets effect on laying Capacity, Egg Characteristics and Economic Returns

Abstract: Increasing demand for soybean meal and fishmeal for use in formulating animal feeds has led to increased prices and moreover their availability in future might be limited. Insect rearing can be part of the solution because they take a short period to mature, require small space and fewer resources to start. This study was designed to evaluate the effect of substituting fishmeal (FM)with black soldier fly larvae (BSFLM) at different inclusion levels, as a protein source in exotic ch...

Phosphorus Availability and Carrot Growth as Influenced by Phosphate Rock Management under Acid Soils in Murang’a and Tharaka Nithi Counties

Abstract: Soils from Central Highlands of Kenya are characterized by low phosphorus (P) availability with crops exhibiting P deficiency symptoms. The objective was therefore to determine the P sorption characteristics of the soils and to assess their standard P requirements in order to recommend the P fertilizer required for different crops in the area. Besides, the study aimed at assessing the efficiency of lemon and pineapple juices and the concentration and time needed to release more tha...

Dietary supplementation of Solanum aethiopicum and Solanecio biafrae leaves alters stress and immune responses, antioxidant status, and meat quality in broilers raised in a hot-dry environmen

ABSTRACT  This study investigated the influence of dietary supplementation of Solanum aethiopicum and Solanecio biafrae leaves, which have nutraceutical properties, on stress response, cytokine expression, antioxidant status, blood chemistry, abdominal fat and meat quality in broilers reared in a hot, dry environment. 2. One day old, Ross 308 chicks (n = 350) were randomly allotted to basal diets containing either no supplement (D1); 2.5 g/kg Solanum aethiopicum leaf (SAL; D2); 5 g/kg SAL (D...

Analysis of the Determinants of Food and Nutrition Security in Nigeria (1981 - 2020).

Food security has become a national priority for the country considering that a vast majority of its 198.1 million population is food insecure. Food and nutrition insecurity is prevalent in Nigeria despite its favourable agroecological endowments. It has a total landmass of 92.4 million hectares, out of which only about 32 million hectares or 34.63 percent are under cultivation. Nigeria, therefore, lacks both the capacity and capability to cater for the food and nutrition requirements of its ...

ABSTRACT Assessment of forest diversity, perception of community towards forest and socioeconomic interaction is very important in order to maintain better forest management. This study was carried out to assess indigenous woody species diversity, socio-economic importance of the forests & drivers of degradation & deforestation in Tolitokal forest. Systematic sampling techniques were applied to collect vegetation data.  Six transect lines were laid along the gradient and a total of 30 plots ...

Mobile Applications Empowering Smallholder Farmers: A Review of the Impact on Agricultural Development
