![]() ![]() ![]() Population genetics analyses (AMOVA, PCA and STRUCTURE) of B. ![]() tabaci MEAM1 haplotype across farmscapes in Georgia. Analysis of 102 mtCOI sequences revealed the presence of a single B. tabaci MED, Dialeurodes citri, Trialeurodes abutiloneus, T. Based on morphological features and mtCOI sequences, five species/cryptic species of whiteflies (B. Thirty-five populations of adult whiteflies on row and vegetable crops and weeds across major agricultural regions of Georgia were collected from fifteen farmscapes. tabaci MEAM1 colonizing different plant species at a farmscape level in Georgia, United States. In this study, mitochondrial COI gene (mtCOI) sequences and six microsatellite markers were used to examine the population structure of B. A farmscape in this study is defined as heterogenous habitat with crop and non-crop areas spanning~8 square kilometers. tabaci could potentially influence their population structure, but this has not been assessed at a farmscape level. ![]() The diversity of agroecosystems invaded by B. Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) are the two most invasive members of the B. We recommend that farmers adapt to using biological control due to its compatibility with other sustainable approaches, such as cultural tools, resistant varieties, and biopesticides for effective management, especially in SSA.īemisia tabaci is a whitefly species complex comprising important phloem feeding insect pests and plant virus vectors of many agricultural crops. We identified natural pest regulation as the option with the greatest potential for this farming system. Here, we critically review the control options for bean pests, particularly the black bean aphid (Aphis fabae) and pod borers (Maruca vitrata). However, significant barriers to their adoption in SSA include a lack of field data and knowledge on the natural enemies of pests, safety, efficacy, the spectrum of activities, the availability and costs of biopesticides, the lack of sources of resistance for different cultivars, and spatial and temporal inconsistencies for cultural methods. Nature-based solutions -in particular, using biological control agents with sustainable approaches that include biopesticides, resistant varieties, and cultural tools-are alternatives to chemical control. Where farmers do use a control strategy, it typically relies on chemical pesticides, which have adverse effects on the wildlife, crop pollinators, natural enemies, mammals, and the development of resistance by pests. However, resource-constrained smallholders in sub-Saharan Africa (SSA) often do little to manage pests. Insect pests are often the most destructive. Common bean (Phaseolus vulgaris) production and storage are limited by numerous constraints. ![]()
