Abstract Male saw-toothed grain beetles (Oryzaephilus surinamensis) and merchant grain beetles (O. mercator) were dissected, and the major differences in their genitalia were reviewed. Differences in the morphology of the internal sac, setae of the lateral lobes, chitinous rods of the median lobe, and setae on the eighth sternite are illustrated with photomicrographs. The only other difference between the 2 species is the outline of the adult head. The dissection procedure is described briefly.

AbstractThe detection of insect infestation by the Canadian Grain Commission is decreased in efficiency by the mortality of adult beetles in the pneumatic sample delivery systems used in terminal elevators in the Vancouver, B.C., area. Dead insects are difficult to see while grading the grain and cannot be extracted by Berlese funnels.The level of mortality varied with the species of beetle and the system tested, but not with the type of grain. In one system the following mortalities were found: Cryptolestes ferrugineus (Stephens), 73%; Oryzaephilus surinamensis (L.), 65%; Tribolium castaneum (Herbst), 65%; and Sitophilus granarius (L.), 22%. C. ferrugineus, the most important insect infesting Canadian grain, sustained an average mortality of 55% in the five systems tested. No consistent mortality pattern was found among the systems with respect to delivery tube length, number of turns, or approximate grain speed. Berlese funnel extraction was found to be inefficient for O. surinamensis and inconsistent for S. granarius.

The Vertical Distribution

AbstractIn order to see if aeration causes grain beetles to become peripherally distributed in bulks of grain, the positions of adults were recorded 7–10 days after they had been placed in the middle of vertical columns of wheat 1200 mm long and 80 mm in diameter. The columns were held at 10 or 25°C, and a downward current of air was passed through half of them. At 10°C, there were more adults of Oryzaephilus surinamensis (L.) at the ends and fewer at the centre of aerated than unaerated tubes when a high airflow was used, and at 25°C, a similar difference occurred when aeration caused cooling, dampening or drying of the grain. Dampening at 10°C and drying at 25°C caused there to be fewer adults of Sitophilus granarius (L.) at the ends and more at the centre of aerated than unaerated tubes. However, vibration at 10°C encouraged the dispersion of weevils. Rhyzopertha dominica (F.) scarcely moved at 10 or 25°C under either aerated or unaerated conditions.

Mortality of three insects; red flour beetle (Tribolium castaneum Herbst), khapra beetle (Trogoderma granarium Everts) and sawtoothed grain beetle (Oryzaephilus surinamensis (L.)) were evaluated via some aqueous plant extracts. The identification of three examined insects was carried out via designing specific primers for each aforementioned species with the use of PCR technique. The toxicity of aqueous plant extracts; eucalyptus (Eucalyptus camaldulensis Dehnh), mint (Mentha canadensis L.) and myrtle (Myrtus communis L.) at three dosages (12500, 25000 and 50000) ppm for 1, 2, 3 and 7 days were tested for their insecticidal activity against examined adults on dried fruits. Percentage mortality of insect was increased with an increase of doses and exposure times, whereas, not influenced significantly by the fruit types. T. castaneum was the most susceptible species, followed by T. granarium and O. surinamensis. Likewise, LC50 values were (3887.25, 10816.34 & 22763.48) on red flour, khapra & sawtoothed grain beetles respectively via using eucalyptus aqueous extract after 7 days on black raisin. While, higher doses required in order to kill fifty percentage of the population via myrtle aqueous extract and thus the LC50 values increased to (14726.86, 18421.43 & 39016.78) on the three aforementioned species respectively.

Grain Beetles

Two types of sense organs are present on the antennae of adult sawtoothed grain beetles, Oryzaephilus surinamensis. Sensilla chaetica are present on all the antennal segments and sensilla basiconica are present on the three segments which compose the antennal club. The intensity of the beetles' humidity response was correlated with the number of sensilla basiconica remaining after amputation of various numbers of antennal segments. On the basis of their morphology and the results of the amputation experiments, it is concluded that at least some of the sensilla basiconica function in hygroreception.
