“…Decision support software (Flinn et al, 2003) can be useful for interpreting sampling data and producing a risk analysis report. Large numbers of spear samples (200+) are required to truly estimate stored-product insect population density (Hodges et al, 1985). Sampling wheat in bins is laborious and the tolerance for damage to high value commodities, i.e., seed wheat, is low.…”

The flight activity of lesser grain borer, Rhyzopertha dominica F. (Coleoptera: Bostrichidae), was monitored at two Foundation seed wheat warehouses during the 2003 and 2004 field seasons, using pheromone-baited Lindgren funnel traps positioned indoors and outdoors. General stored-product insect activity was also monitored using unbaited sticky traps positioned inside the warehouses around overhead doors. Pheromone-baited traps were useful for monitoring R. dominica activity, however insect captures decreased when lures were not changed weekly. Flight peaks were documented in early May and again from September through October, and insect captures inside warehouses correlated with timing of outdoor captures. Multiple regression analyses showed that slightly more than half of the variability in R. dominica captures could be explained by mean ambient air temperature and wind speed during the 2 h preceding sunset. Stored-product Coleoptera captured on unbaited glue boards around overhead doors included Ahasverus advena, Cryptolestes ferrugineus, R. dominica, Sitophilus oryzae, Tribolium castaneum , Trogoderma variabile , and Typhaea stercorea. Door gaskets significantly reduced the number of insect captures on glue boards placed around the overhead doors, and generally restricted their entry to ground level. These studies demonstrated that outdoor pheromone-baited traps are effective monitoring tools for determining when grain-handling facilities are most susceptible to infestation and that exclusion may be an effective component of a pest management program.

“…These losses are mainly due to the pests attack associated with the variation of temperature in the granaries. The most common storage insects are Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae), Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae), and the Sitophilus zeamais (Coleoptera: Curculionidae) [9][10][11]. From these storage insects, Prostephanus truncatus (Horn) and Sitophilus zeamais (Motschulsky) are the major insects observed in maize stocks [8,12].…”

Majority of post-harvest losses of several maize varieties observed in various storage systems in northern Benin are mainly caused by storage insects due to changes in climatic parameters. The objective of this study is to evaluate the levels of insect pest infestation of three maize varieties stored in storage systems at different temperature. In 18 villages at Alibori, maize farmers were surveyed through a participatory research approach and their storage structures were also visited. The temperature of all storage structures were noted. Weight loss of samples, numbers of Prostephanus truncates, Sitophilus zeamais and perforated grains were evaluated. In total, three maize varieties and three different groups of storage systems were identified during field observations. All the three maize varieties stored in the first storage systems group built with plants were less infested and had acceptable nutritional quality than the maize grains stored in the second group built in banco and third group built with tarpaulin. In these storage systems, the yellow maize variety was the most attacked, followed by the white maize variety and finally the mixed color of yellow and white maize variety the less attacked. Effective post-harvest management of stored products requires clear monitoring criteria of climatic parameters and effective implementation of abiotic and biotic factors.

“…Numbers captured may, therefore, represent only a relative proportion of those present, but because of their simplicity, convenience, availability and ease of operation, pitfalls offer a practical method for sampling populations of certain epigeal fauna (Gist & Crossley, 1973;Luff, 1975). For example, they have been used extensively in brassica and cereal crops (Coaker & Finch, 1971;Sunderland & Vickerman, 1980) and recently have been shown to be more effective than spear sampling for detecting low infestations of surface active beetles attacking stored grain (Hodges et al, 1985;Cogan et aL, 1985;Hillmann, 1990;Obeng-Ofori, 1990).…”

Pitfall trap capture for Sitophilus oryzae (L.), S. zeamais (Motschulsky), S. granarius (L.), Tribolium confusum (Duval), T. castaneum (Herbst); Oryzaephilus surinamensis (L.), Cryptolestes pusillus (Schonherr), Rhyzopertha dominica (Fabr.), and Prostephanus truncatus (Horn) in millet was assessed by visual and time‐lapse video recordings. The behaviour of different beetle species in arenas containing millet was monitored over 24 h and the frequency of encounters with the trap rim resulting in capture recorded. The capture efficiency of four types of pitfall traps (i.e. polystyrene, polythene, glass and tin‐plated steel can) with rims exposed or submerged below the millet surface level were compared. Capture was related to beetle size, locomotory rate, and beetle behaviour at the trap rim as well as trap design and placement. The lighter and smaller species were least captured. Glass jars were more effective than plastic and metal containers. Traps placed with their rims submerged below the grain surface level were more efficient than those with rims exposed. Capture rate was unrelated to trap size. The frequency of encounters with trap rims was not correlated with capture rate. Three types of avoidance behaviours at the trap rims i.e. probing, skirting and spontaneous retreat, were related to capture rate, spontaneous retreat being the most effective escape mechanism and probing least.
