“…This corroborates with a study by Ochilo and Nyamasyo [13] that bean aphids and stem maggots can account for yield losses of up to 100%. These insect pests have a high chance of damaging crops and reducing yields, thus causing visible and economical losses that can greatly affect smallholder farmers [34,35]. During the focus group discussions, farmers explained that the major loss of their common bean is caused by insect pests.…”

Weeds and insect pests are among the serious constraints in common bean production in most rural communities. A survey of 169 smallholder farmers was conducted in two common bean-growing districts in northern Tanzania. The aim was to assess farmers’ knowledge, perceptions, current management practices and challenges in order to develop sustainable weed and insect pest management strategies. The results revealed that 83% of farmers perceived insect pests as the major constraint in common bean production, while 73% reported weeds as the main drawback. Insect pest management was mainly achieved through the use of synthetic pesticides, however, only 24% of farmers were able to apply, the rest could not afford due to high cost, limited access and lack of knowledge. Only 6.5% of farmers were aware of non-chemical methods and 2.1% did not practice any method in managing insect pests, both in the field and during storage. Moreover, farmers generally relied on experience in managing insect pests and weeds, and about 43% did not see the need to consult extension officers. These findings indicate that there is a need to sensitize and train farmers on the sustainable methods for pest and weed management in common bean farming systems in northern Tanzania.

“…In addition to above biotic stresses, a number of insect pests such as Sitona weevil ( Sitona lineatus L.), cowpea aphid ( Aphis craccivora Koch) and black bean aphid ( A. fabae Scopoli) cause damage by direct feeding as well as by transmission of viruses (Mwanauta, Mtei, & Ndakidemi, ). There are currently integrated pest management options to control these insect pests as described by Redden et al.…”

Faba bean is an important legume crop because of its high-yield potential and nutrition-dense grains. There have been significant achievements in faba bean improvement in the last four decades, which led to the doubling of the global yield average. This study reviews the genetic diversity, the breeding methodologies, major achievement on biotic and abiotic traits, and the recent molecular approaches. The high genetic diversity among faba bean accessions has been useful for increasing yield potential of the crop. Substantial increase in yield potential can be gained through the development of cultivars in open pollinated conditions. In the past, many faba bean varieties that are tolerant to abiotic and biotic stresses were released worldwide. The average yield gains varied from 1.65% per year in Syria to 4.17% per year in Ethiopia. The recent advances in molecular technologies will be used to develop more coherent genetic maps, which would also facilitate assembling and ordering genomic scaffolds in a future genome-sequencing effort and molecular-breeding approach.

“…For instance, this crop is produced by smallholder growers whose farm size is ranging from 0.25 to one hectare; climatic variability and pest and disease attack remain some of the critical challenges. However, the highest damage and yield losses on common bean production emanate from pest and disease attack with average yield loss of 10 to 37 percent (Nderitu et al, 2010; [3,4]). So far, the damage by bean aphid is critical at all development stages of the plant growth since it feeds on young leaves, flower buds, and young pods.…”

Common beans (Phaseolus vulgaris) remain an important dietary protein source in Malawi. However, its production is highly hindered by insect pest and disease attack. The study aimed at evaluating the effectiveness of Tephrosia vogelii and Tephrosia candida extracts against bean aphid (Aphis fabae). The evaluation involved two botanical extracts at three different concentrations (0.5%, 2%, and 5% w/v) against bean aphid. Plant extracts (leaves) were air-dried and milled. Powders were then soaked in a 2-litre plastic bucket of cold water. Results indicated that there was significant difference (P<0.05) among treatments. The effectiveness of the treatments was based on reduction in aphid population per plant, pod length, and bean yield. Pod length and bean yield were higher in T. vogelii and Karate as compared to untreated and T. candida. There was a high mortality rate of aphid on the plots treated with T. vogelii compared to plots treated with T. candida at the same concentration. Though these two plant extracts were not as effective as the synthetic insecticide in reducing aphid population, they were considerably and significantly found to be effective; hence, its use by poor-resource farmers is recommended in the protection of bean against aphid.
