“…In general, insect behavior is affected by the interaction of many different physical, chemical, and biotic factors in their environment [13]. These factors include light intensity, relative humidity, temperature, food availability, grain moisture content, size and variety, grain store design and construction materials, disturbance caused by insect density and the presence of other arthropod species including predators and parasitoids, vertebrates and disease micro-organisms [14][15][16]. Food preference is a single criterion in assessing the suitability of stored product pests to various food fractions.…”

Oryzaephilus surinamensis is one of the stored product insect that commonly found in Malaysia. The biological study through host range or food preferences of O. surinamensis is important for the development of sustainable management practice to control its infestation. The objective of this study was to identify the food preference of O. surinamensis to different plant products in relation to food type and moisture content. Twenty adult of O. surinamensis were exposed to three different group of food; dried fruits (date, raisin, apricot, fig), grain/cereals (rice, barley, oat grout, dried maize), and nuts (almond, ground nut, walnut, cashew nut) for 240h in laboratory Kulliyyah of Science, IIUM Kuantan. Moisture content in each food was also measured. It was found out that the most preferred food by O. surinamensis is oat groat of cereal grain group with medium level of moisture content. Further analysis on food moisture suggested that under current experimental conditions (temperature of 27℃ and 64% relative humidity within 240h of exposure), food moisture content does not affect pest infestation and distribution.

“…(Nansen et al, 2004;Mason and McDonough, 2012). Based on these basic successional patterns (Table 1), the presence of the different species in general successional patterns can serve as an indicator of grain quality (Coombs and Woodroffe, 1973;Allotey, 1991). For example, the presence of hairy fungus beetles and psocids can indicate deteriorating grain quality and they may also hasten deterioration as The importance of ecological succession of community colonization by stored product insects, degradation of commodity, and decreasing IPM tactic efficacy in bulk storage over time.…”

“…Bulk storage of post-harvest products can entail containers of a variety of sizes and shapes. For most low-income countries, most grains (75-85%) are stored on-farm or by small-volume traders (McFarlane and Prevett, 1984;Allotey, 1991). However, specific successional patterns of infestation have rarely been documented in these post-harvest ecosystems.…”

The environment in which postharvest crops are processed and stored is a dynamic ecosystem influenced not only by environmental factors such as temperature and humidity, but also by biotic influences such as humans and insects. Abiotic influences such as variation in landscapes of warehouses, processing facilities, storage and shipping containers, and urban and agricultural settings can also drive changes in ecosystem processes for insects living in a postharvest system. Principles of community ecology can help to tease apart broad interactions among the environment including succession, interactions with conspecifics that lead to competition and niche partitioning, behavioral ecology variation, and physiology and developmental changes. Focusing on these concepts for integrated pest management (IPM) for stored product insect pests can help pest managers to better predict risk thresholds and develop targeted approaches for treatments. Typically, pest management decisions focus on single species without regards to the interactions with other species. Without consideration of the entire ecosystem, targeted treatments for one species can have both direct and indirect impacts on other species that may have equally detrimental effects on stored products. Current knowledge of stored product ecosystems lags behind what is known for field pest ecosystems, and hinders our ability to design effective control strategies for the whole system. Here, we present a review of work on stored product insect pests using a community ecology lens. We analyze how the current state of the knowledge regarding species interactions and variation and incorporating factors such as movement, species interactions, energy transfer models in succession, behavior, and effects of climate change in ecological modeling can be used to better develop and implement more effective postharvest IPM. Implementing these concepts will significantly improve management of these insects and can help reduce time and cost associated with managing and treating insect infestations.

Environmental and human health problems associated with the use of synthetic pesticides have prompted the demand for non-polluting, biologically specific insecticides. The current study assessed the losses caused by Tribolium confusum and its control by diatomaceous earth and the effect on Aspergillus flavus spore dispersal during storage of groundnuts. When losses due to Tribolium confusum were assessed over a period of 60 days, it was found that an increase in insect population in stored groundnuts resulted in increased weight loss of stored groundnuts. The true weight loss due to insect feeding was 0.60 g per 400 g of stored groundnuts. When diatomaceous earth (DE) was applied to groundnuts followed by the introduction of insects in a compartment (A), increased mortality of insects with increased diatomaceous earth concentration was observed. For a concentration range of 0-2.5 g DE/kg groundnut, 2.5 g/kg treatment was the most effective (only 5 surviving T. confusum adults out of 50 were recovered in samples treated with 2.5 g/kg compared to 38 adults in the control samples). Larval emergence from groundnuts treated with DE also declined with increased diatomaceous earth concentration. When groundnuts were inoculated with A. flavus spores, followed by DE application and T. confusum introduction into compartment A, the transfer of spores between inoculated groundnut samples in compartment A and uninoculated samples in compartment B was reduced. The mean A. flavus spore concentration recovered from initially sterile compartment B was1.08x10 3 ; while it was 45 in the control and in samples treated with 2.5 g/kg dosage respectively. There was a significant difference in the mean numbers of spores recovered from groundnuts in different compartments (A, B) (H = 13.99, df = 4 and P = 0.007). Thus, from this study, losses due to T. confusum on groundnuts and fungal spore transfer in storage by this insect can be minimized by the application of diatomaceous earth (Protect-It™) to stored groundnuts.
