“…These were both reared on whole maize grains in a controlled environment. Culture conditions of 28 ± 2°C, 65% relative humidity and 12L: 12 D photo regime [15,16] were used. The insects were placed in a plastic bowl covered with a nylon mesh and left under the sun for three hours so that insects infested with mites would die.…”

Studies were carried out under laboratory conditions of 32 ± 2°C and 58-88% r.h. to determine the effectiveness of the triple-layer hermetic bag against the Larger Grain Borer, Prostephanus truncatus (Horn) and the maize weevil, Sitophilus zeamais (Mot) on stored maize. Three storage bags (Triple-layer hermetic bag, Jute and Polypropylene) and three maize varieties (Obatanpa, Abrodenkye and Kamangkpong) widely cultivated in Ghana were used in the study. A factorial experiment was conducted involving 5 kg of each maize variety with moisture content between 12.5-14%. These were stored in the various bags and a destructive sampling of 54 bags (27 bags for each insect species) was done each month for a 6 month storage period. Percentage damage, weight loss and mean development periods of insect numbers were determined. Mean grain damage and weight loss were significantly different (p<0.001) in the different storage bags. The triple-layer hermetic bag recorded the least mean weight loss of 2.94% while jute and polypropylene bags recorded higher mean values of 19.55% and 23.65% respectively. Prostephanus truncatus caused the highest mean weight loss of 17.19% while S. zeamais caused 10.57%. The high yielding improved variety (Obatanpa) was the most susceptible with a mean weight loss of 16.75% whiles Kamangkpong recorded the least susceptibility to both insect species with a mean weight loss of 11.09%. Abrodenkye recorded 13.55% weight loss. Moisture content and insect numbers were significantly different (p<0.001) in the various bags. It is therefore recommended that the triplelayer hermetic bag should be used for quality preservation of maize.

“…Pheromone-baited traps have been a practical monitoring device for tracking outdoor populations of Prostephanus truncatus (Hodges, 2002), a closely related member of the Bostrichidae, but information on long-term outdoor monitoring of R. dominica around grain storage facilities is limited (Throne & Cline, 1991;Dowdy & McGaughey, 1998). Better knowledge of pest behavior and population dynamics is needed for developing novel control strategies and for precisely targeting pest management tactics.…”

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.

“…It is a key requirement for IPM strategies for stored grain (Wakefield, 2006). Although extensive information is available on aggregation pheromone use in monitoring predominant storage beetle pest species (Hodges, 2002;Olsson et al, 2006), the relationship between the number of insects caught in a trap and those found on a commodity or product has still not been clearly established, making the interpretation of the trap catch data difficult (Toews et al, 2005).…”

“…In addition, the efficacy of the sticky surfaces to trap insects may be reduced when the surface is coated by dust or when there are already too many insects caught. Hodges (2002) concluded that trap catch data might not indicate the size of the population in the habitat but only indicate the magnitude of dispersal activity. Factors influencing flight activity of P. truncatus are not yet well understood, but research has shown links with environmental variables such as day length, relative air humidity and temperature (Nansen et al, 2001;Hodges et al, 2003).…”

The study sought to confirm reports by farmers and agricultural extension personnel of Prostephanus truncatus (Horn) attacking harvested maize in Mashonaland West and Mashonaland Central provinces of Zimbabwe and to map out, using pheromone trap catch data, the distribution of the pest in the country. A survey of 296 respondents confirmed the presence of P. truncatus in five districts of the provinces. Some respondents reported that the first few sightings of the pest were in 2005 or earlier, while the majority mentioned the 2006/2007 storage season. The map showed a more concentrated distribution of P. truncatus in the northern part of the country moving further inland towards the central and eastern parts of Zimbabwe, indicating possible spread of the pest from the neighbouring countries Zambia and Mozambique. The results of the study indicate legitimate concerns over food security with respect to stored maize grain and seed. The occurrence of P. truncatus in the country has serious implications on training of extension agents and packaging of extension messages that need to be disseminated to the farming community to reduce the impact of the pest. This is the first evidence-based and official documented report of P. truncatus occurrence in Zimbabwe.
