Common bean production in Africa suffers from different constrains. The main damage is caused by insect pest infestations in the field. The most common insects pests which attack common bean in the field are the bean stem maggot (Ophiomyia phaseoli), ootheca (Ootheca bennigseni) and aphids (Aphis fabae). Currently, few farmers in Africa are using commercial pesticides for the control of these insect pests. Due to the negative side effects of commercial pesticides to human health and the environment, there is a need for developing and recommending alternative methods such as those involving agronomic and botanical/biological measures in controlling common bean insect pests. This review aim to report the most common insects pests which attack common bean (Phaseolus vulgaris L.) in the field and explore the potential of agronomic, biological and botanical methods as a low-cost, safe and environmentally friendly means of controlling insect pests in legumes.

“…Agronet covers have, on the other hand, been reported to increase air temperature by 15% to 20% compared with open field treatments [15,45] which could have promoted the transformation of methyl chavicol and other volatiles from liquid to gaseous state in the current study. Owing to the nature of covers in reducing air circulation [14] this therefore may have led to the concentration of these volatile compounds inside the agronet cover. Therefore, it is possible that agronet covers and companion cropping may have lowered B. tabaci infestation through either combined effects or one of the effects as mentioned.…”

“…Agronet covers, which refers to woven or knitted plastic fibres connected together to form a porous geometric structure that allow fluids (gases and liquids) to go through [12], has proved successful in protecting different crops from extreme weather and insect pests [13][14][15][16]. The use of these agronet covers has also served as a means of reducing or even preventing often indiscriminate insecticide applications by small scale growers and at the same time improve yield and quality of crops [17].…”

“…The use of insecticide treated net covers has also proved effective against a wide range of pests such as the invasive tomato leafminer Tuta absoluta [20]. Agronet covers also protect agricultural crops from excessive solar radiation and other environmental hazards thus enhancing plant microclimate for better crop performance [14]. Pek and Heyles [21] recorded better regulation of air temperature, reduced crop stresses and better crop performance with the use of netting technology compared to open field production of vegetable.…”

Synergistic Effects of Agronet Covers and Companion Cropping on Reducing Whitefly Infestation and Improving Yield of Open Field-Grown Tomatoes

Tomatoes (Lycopersicon esculentum Mill) are one of the biggest vegetable crops in the world, supplying a wide range of vitamins, minerals and fibre in human diets. In the tropics, tomatoes are predominantly grown under sub-optimal conditions by subsistence farmers, with exposure to biotic and abiotic stresses in the open field. Whitefly (Bemisia tabaci Gennadius) is one of the major pests of the tomato, potentially causing up to 100% yield loss. To control whitefly, most growers indiscriminately use synthetic insecticides which negatively impact the environment, humans, and other natural pest management systems, while also increasing cost of production. This study sought to investigate the effectiveness of agronet covers and companion planting with aromatic basil (Ocimum basilicum L.) as an alternative management strategy for whitefly in tomatoes and to evaluate the use of these treatments ontomato growth and yield. Two trials were conducted at the Horticulture Research and Training Field, Egerton University, Njoro, Kenya. Treatments comprised a combination of two factors, (1) growing environment (agronet and no agronet) and (2) companion planting with a row of basil surrounding tomato plants, a row of basil in between adjacent rows of tomato, no companion planting. Agronet covers and companion cropping with a row of basil planted between adjacent tomato rows significantly lowered B. tabaci infestation in tomatoes by 68.7%. Better tomato yields were also recorded in treatments where the two treatments were used in combination. Higher yield (13.75 t/ha) was obtained from tomatoes grown under agronet cover with a basil row planted in between adjacent rows of the tomato crop compared to 5.9 t/ha in the control. Non-marketable yield was also lowered to5.9 t/ha compared to 9.8 t/ha in the control following the use of the two treatments in combination. The results of this study demonstrate the potential viability of using companion cropping and agronet covers in integrated management of B. tabaci and improvement of tomato yield.

Bemisia tabaci (Gennadius), the vector of Tomato chlorosis virus (ToCV), is one of the major pests of tomato (Solanum lycopersicum L. var. lycopersicum), potentially causing up to 100% yield loss. The purpose of this research was to effectively reduce intrusion by B. tabaci and control damage from ToCV in protected cultivations. The treatments included the use of a regular solar greenhouse as a control (CK); greenhouses I and II with 60-and 80-mesh insect-proof nets, respectively, that were installed in both houses at the front and upper ventilations; and greenhouse III with the addition of not only the 80-mesh insect-proof net as in greenhouse II but also a ventilating pipeline to the back wall. The effects of mesh size and back wall ventilation on the greenhouse temperature and humidity, number of B. tabaci, and level of ToCV infection were studied. Under all conditions tested (from 2014-2016), the temperature of greenhouse III with installed netting was reduced by drilling holes through the back wall and nonsignificant difference existed in the average relative humidity between greenhouses II and III. Importantly, the number of B. tabaci and ToCV infection rate were effectively controlled in greenhouse III, ranging from 0.03 to 0.33 adults per sampled plant and from 0% to 6.67% of virus incidence. Thus, installing 80-mesh insect-proof netting at the front and upper ventilation areas as well as adding a ventilating pipeline to the back wall could effectively reduce the number of B. tabaci and prevent ToCV damage.
