“…Destacaram-se como inimigos naturais cinco espécies de Coccinelidae. Esses besouros conhecidos por "joaninhas" embora se alimentem preferencialmente de pulgões predam também ácaros, cochonilhas e tripes (NDAKIDEMI et al, 2016). A espécie Eriopis connexa (Ger.)…”

As plantas hospedeiras servem como refúgios para os insetos no período de entressafra, onde se alimentam, acasalam ou ficam em diapausa aguardando novo plantio para que os indivíduos sobreviventes se dirijam à lavoura. Este estudo teve como objetivo avaliar a diversidade de insetos em treze espécies de plantas espontâneas próximas a áreas de cultivo de algodão e milho no período de entressafra. Foram selecionadas quatro plantas hospedeiras e realizadas avaliações mensais por observação direta e identificados os insetos. Foi realizada a análise faunística determinando-se a riqueza, índice de diversidade de Margalef e Shannon-Wiener e índice de equitabilidade. Foram coletados indivíduos pertencentes às ordens Coleoptera, Hemiptera, Hymenoptera, Diptera, Lepidoptera e Neuroptera, tendo com maior incidência a praga Diabrotica speciosa. Entre as plantas hospedeiras próximas a cultura do algodão foram encontradas as ordens de insetos Coleoptera, Hemiptera, Hymenoptera, Diptera e Neuroptera, sendo Dysdercus ruficollis a principal representante. Os índices faunísticos mais elevados foram verificados nas plantas Coniza sp. e Cenchrus echinatus próximas a área de cultivo de milho e Commelina bengalensis e Parthenium hysterophorus nas plantas próximas a área de cultivo de algodão.

“…The use of pesticidal plants as artificial pesticide replacers has also been reported [22]. The pesticidal plants also provide ecosystem services like pollination and biological pest control in agricultural fields [23]. Tooker and Hanks (2014) [24] identified several species of hymenopteran which visited the pesticidal flowering plant hosts.…”

Declines in populations of pollinators in agricultural based landscapes have raised a concern, which could be associated with various factors such as intensive farming systems like monocropping and the use of non-selective synthetic pesticides. Such practices are likely to remove beneficial non-crop plants around or nearby the cropped fields. This may in turn result into losses of pollinators due to loss of the natural habitats for insects therefore, interfering the interaction between beneficial insects and flowering crop plants. Initiatives to restore friendly habitats for pollinators require multidisciplinary approaches. One of these could be the use of pesticidal flowering plants as part of field margin plants with the aim of encouraging the population of pollinators whilst reducing the number of pests. Farmers should be fully engaged in the efforts of creating conducive environments to pollinators and be well equipped with the knowledge of proper habitats management strategies in agricultural fields. Developing appropriate conservation strategies to combat decline of pollinators is of high importance and thus there is a need to evaluate management practices, which potentially favour the populations of pollinators. Therefore, this review aims at unravelling available evidences on habitats manipulation options through provision of flowering plants along the field margins that have shown to increase plant biodiversity surrounding the cropped fields. It also summarizes the options for increasing plant biodiversity, which have improved habitats for the pollinating insects and beneficially boosting pollination services in agro-ecosystems.

“…Another important IPM component is the deployment of macro agents including predators, parasitic wasps and nematodes for pest control. Common predators of insect pests include praying mantis, spiders, earwigs, true bugs, ladybird beetles, ground beetles, lacewings, and hoverfly larvae (Ndakidemi et al, 2016). Introducing or conserving these predators in cowpea fields can provide effective and sustainable control of insects such as aphids, thrips, and lepidopterans by preying on their eggs, larvae, and adults and reduce the need for chemical insecticides (Mweke et al, 2020;Otieno et al, 2020).…”

Cowpea is an important and climate-resilient grain legume for human and livestock nutrition worldwide. Its grains represent a valuable source of protein for rural families in Sub-Saharan Africa while its haulms offer nutritious fodder for livestock, especially, in the Sahel regions. Cowpea production, unfortunately, faces substantial challenges of field and storage insect pests which can cause up to 100% losses. The use of synthetic pesticides, although providing farmers with a good level of pest control, has underscored the critical need for the development of integrated pest management (IPM) alternatives, due to their detrimental effects on humans, animals and the environment. This review examines recent advances in West Africa in cowpea IPM approaches, highlighting research on host plant resistance, biological control, biopesticides, good cultural practices, and on-farm participatory research and training undertaken to support sustainable cowpea production. Numerous IPM options have been developed, tested and validated for combating cowpea insect problems in West Africa by research institutions and disseminated through farmer field schools (FFS), field demonstrations, training sessions, and community-based education. Reviewing these environmentally safer and scalable IPM innovations will provide cowpea stakeholders with insights into workable, sustainable solutions for minimizing crop pest problems, reducing reliance on harmful pesticides and ultimately ensuring the long-term viability of cowpea production and its contribution to food security.
