“…Different non-crop plants have been reported to attract beneficial insects in crop ecosystems due to ecological relationships between the plant resources and insect biology [12]. 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].…”

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.

“…Also, lack of storage facilities and inadequate materials needed for preservation of the fruits among others make the situation alarming and eventually lead to artificial fruit scarcity, fruit insecurity and safety in many households most especially outside the season of the fruits. In cases when some of these fruits are preserved, they are done using synthetics or chemicals which are detrimental to health status and environment of consumers (Mkindi et al, 2015;Youmsi 2017;Sergio et al, 2017).…”

The rate at which agricultural produce such as fruits are being infected by pests or spoilt as a results of lack of appropriate natural preservatives posed threat to food security and safety in many communities of Ogun State. However, there is need for study that can evaluate natural preservatives and physicochemical properties of some plants. In the present study, survey of indigenous plants commonly used for preservation of fruits was conducted using one hundred structured questionnaires randomly administered on fruit-sellers to elicit information on spoilage as threat affecting sales of fruits in Abeokuta. Also, biochemical constituents and physicochemical properties in the leaves of most plants used for fruits preservation were determined using standard procedure. Data were analysed using Statistical Analysis System. Means were separated using Duncan’s Multiple Range Test at 5% level of significance (p < 0.05). Nauclea latifolia, Chromolaena odorata, Psidium guajava, Azadirachta indica, Moringa oleifera and Aloe vera were the plants commonly used for preservation of fruits in the study area. Fruit spoilage (84.0%) was the major threat affecting the sales of fruits in Abeokuta. Saponin (0.68±0.03 mg/100g) and terpenoid (0.22±0.08 mg/100g) were significantly higher (p < 0.05) in A. indica leaves as well as alkaloid (16.49±0.01 mg/100 g) in M. oleifera leaves. Also, phenol (0.41±0.02 mg/100g) and flavonoid (0.71±0.09mg/100g) were significantly higher (p < 0.05) in C. odorata and A. vera leaves. Phytate (0.35±0.01 mg/100 g) and oxalate (0.32±0.03 mg/100 g) were significantly higher (p < 0.05) in the leaves of C. odorata. Furthermore, specific gravity of M. oleifera leaves (0.98±0.05) was significantly higher (p < 0.05) compared with leaves of other plants. Iodine value (81.65±0.03 mg/100 g) and acid value (22.72±0.07) were significantly (p < 0.05) higher in Aloe vera leaves. The study revealed that spoilage was the major challenge facing the sales of fruits in Abeokuta. Also, leaves of the plants contained high proportions of natural preservatives and physicochemical properties. Spoilage was the major challenge facing the sales of fruits, however, leaves of the plants contained high amount of preservative and physicochemical parameters that could be adopted for preservation of fruits.

“…2 Technological improvements in farming have meant that local farmers have been able to reduce their use of synthetic pesticides, which can have a negative effect on the environment and farmers' health. 3 Recently, several varieties of corn that have high yield potential have been developed, but their resistance to pest of stored product s is not yet known. During the storage period of corn production, damage can be caused by Sitophilus zeamais.…”

Agricultural produce is commonly stored in warehouses after the harvest period, before being utilized and fulfilling the crop stock. However, crop threats are not only present during cultivation and harvest, but crops can also be infected during storage, which leads to agricultural loss. This research aimed to observe the resistance level of corn varieties of Bisma, Bisi 18, Bisi 19, Pioneer 21, Pioneer 29, and Pertiwi 3 to the Sitophilus zeamaispest of stored product insects. This resistance was based on the mechanism of non-preference (antixenosis) resistance, measured with the Free Choice Test Method (FCTM), and antibiosis resistance mechanism, measured with the No Choice Test Method (NCTM). The results showed that based on the susceptibility index (Dobie, 1974), corn varieties of Pertiwi 3 were categorized as resistant to S. zeamais pests, while the varieties of Bisi 19, Bisma, Bisi 18, Pioneer 21 and Pioneer 29 were moderately resistant.
