“…It would also allow for an increase in number of entry holes into the grain probe trap. In comparisons of the WBII probe trap and the Lexan probe trap, the WBII probe traps tend to capture more insects, but the differences were not always signiÞcant (Barak et al 1990;Subramanyam et al 1993;Fargo et al 1994). In addition to differences in hole size, shape and angle, there are also differences in hole spacing (i.e., offset versus adjacent holes) between the two probe traps.…”

The relationship between number of holes in a grain probe trap body and capture of stored-grain pests was determined in laboratory tests using adults of the rice weevil, Sitophilus oryzae (L.), the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the red flour beetle, Tribolium castaneum (Herbst). Polyvinylchloride (PVC) probe bodies were attached to electronic sensor heads, and insect captures were recorded electronically using an Electronic Grain Probe Insect Counter (EGPIC) system. In comparisons among PVC probe trap bodies with 60-492 holes, tested at 71 insects per kg in 2.8 kg of soft wheat in cylindrical mini-silos, sawtoothed grain beetle and rice weevil captures were directly related to number of holes in the probe trap body, but there was no relationship for red flour beetle capture. Subsequent tests were conducted comparing sawtoothed grain beetle and rice weevil captures in a PVC probe body with 210 holes over a 40-cm long trapping surface with two commercially available probe traps, a polycarbonate (Lexan) probe trap with 180 holes over a 14-cm long trapping surface and a polyethylene (WBII) probe trap with 750 holes over a 34-cm long trapping surface. The highest percentage capture of both species was in the WBII probe trap, but the 210-hole PVC probe body was as effective as the Lexan probe body for rice weevils and sawtoothed grain beetles at 71 and 17 insects per kg of wheat, respectively.

“…Several studies have described the potential use of baited (White and Loschiavo 1986, Fargo et al 1994, Plarre 1996 and unbaited (Hagstrum et al 1998, and references therein) probe trap catches of beetles as a decision support tool for estimating insect populations in stored grain. However, as pointed out in several studies (Vela-CoifÞer et al 1997, Hagstrum et al 1998, it is difÞcult to estimate absolute insect density from probe trap catches because there are many interacting factors that affect the relative performance of the probe traps, such as trap design, grain temperature, trapping duration, insect density, trap placement, and insect species.…”

“…Similarly, Collins et al (2004) used non-pheromonal attractants sources for the detection of Oryzaephilus surinamensis (L.), Sitophilus granarius (L.) and Cryptolestes ferrugineus (Stephens) and showed that the development of a multi-species lure is feasible. However, in laboratory experiments using perforated probe traps, Fargo et al (1994) reported that the addition of pheromone did not increase captures of adult S. oryzae. In our case it is likely that adults responded more vigorously to traps that contained their pheromones shortly after their introduction, but following "saturation" the refuge-seeking behaviour occurred independently of the chemical stimuli.…”

Abstract. The behavioural responses of two species of stored-product beetles, Sitophilus oryzae (L.) and Tribolium confusum Jacquelin du Val, to certain stimuli were studied in laboratory choice tests. The results of these experiments indicated that, with one species present, S. oryzae and T. confusum adults were equally attracted to traps baited with the aggregation pheromone of that species and to traps baited with both pheromones. In contrast, when both species were present, neither S. oryzae nor T. confusum showed specific behavioural trend towards a stimulus. Traps baited with 1 g of a mixture of plant extracts were significantly more attractive for both species than unbaited traps, but this response was highly influenced by the number of individuals of each species released. Traps baited with filter papers that were previously contaminated by live adults of both species were particularly attractive for S. oryzae, but not for T. confusum. Traps that contained 10 seeds damaged by S. oryzae were significantly more attractive than traps containing an oil lure or control traps for S. oryzae, but not for T. confusum. The addition of oil to the seeds did not affect the attractiveness of the trap for S. oryzae. Traps that contained 20 live S. oryzae adults were significantly more attractive than traps containing 20 dead S. oryzae adults or control traps. No significant differences were noted between traps containing 20 dead S. oryzae adults and control traps. The presence of S. oryzae adults in traps did not affect the response of T. confusum.
