“…These disadvantages are largely obviated in the last procedure. The bodies of large insects in thermal gradients may span several degrees (33), and in small species the steepness of the gradient may affect the precision of temperature selection (4). Uneven heating with a lamp may result in variations in temperature within the body, and very rapid heating can alter apparent MVT (M. L. May, unpublished observations).…”

“…Adult red ßour beetle, Tribolium castaneum (Herbst), can move when temperature is higher than 15ЊC, and the rate of movement increases from 14 mm/min at 20ЊC to Ϸ28 mm/min at 30ЊC (Surtees 1965). Males tend to disperse more readily than females (Surtees 1965, Hagstrum et al 1998), but both sexes prefer temperatures of 30ЊC (Graham 1958, Amos and Waterhouse 1969, Yinon and Shulov 1970, Langer and Young 1976, Hagstrum et al 1998, and they achieve almost the same displacement in unit time by moving along a straighter path (Surtees 1965). Studies were generally done without food or with only a thin layer of ßour except for the study by Hagstrum et al (1998), who used a 61-cm steel trough Þlled with wheat.…”

The movement and redistribution of adult Tribolium castaneum (Herbst) in stored grain provide important information for detection of insect pests and for simulations of their distribution in grain bins. Movement and redistribution of T. castaneum adults in 1 or 6 d and in wheat or corn were determined in a 100 by 100 by 1000-mm acrylic box with a 10 degrees C/m temperature gradient (from 20 to 30 degrees C) or at a uniform temperature (20, 25, and 30 degrees C). In a vertical corn column with a uniform temperature, approximately 15 and 25% of adults moved to the top or bottom section in 6 d, respectively; and < 30% of adults were recovered in 1-d movement in the middle two sections where insects were initially introduced. In a horizontal or vertical wheat column, > 90% of the adults were recovered in the two middle sections where insects were introduced after 6 d. Adults responded to the temperature gradient and preferred the warmer areas in both wheat and corn. The slower movement in wheat is probably caused by the small granular space in bulk wheat than in bulk corn.

“…Because insects show oriented responses to temperature and moisture gradients (Amos 1968, Amos and Waterhouse 1969, Arbogast and Carthon 1972, Perttunen 1972, Arbogast 1974 and to the distribution of dockage (foreign material, broken grain, and Þne farinaceous material) (McGregor 1964), we would expect these to be among the major factors determining insect distribution in stored grain. Contour analysis of trap catches indicated that, at their highest population levels, beetles were concentrated along the wall of the bin from northwest to east (Fig.…”

Automated methods of monitoring stored grain for insect pests will contribute to early detection and aid in management of pest problems. An insect population infesting stored oats at a seed processing plant in north-central Florida was studied to test a device for counting insects electronically (Electronic Grain Probe Insect Counter, EGPIC), and to characterize the storage environment. The device counts insects as they fall through an infrared beam incorporated into a modified grain probe (pitfall) trap and transmits the counts to a computer for accumulation and storage. Eight traps were inserted into the surface of the grain bulk, and the insects trapped were identified and counted manually at weekly intervals. Grain temperature and moisture content also were recorded for each trap location. Manual and automatic counts were compared to estimate error in the EGPIC system. Both over- and undercounting occurred, and errors ranged from -79.4 to 82.4%. The mean absolute value of error (+/- SE) was 31.7% (+/- 4.3). At least 31 species, or higher taxa, were detected, but the psocid Liposcelis entomophila (Enderlein) and the foreign grain beetle, Ahasverus advena (Waltl), accounted for 88% of the captured insects. Species diversity, phenology, and spatial distribution are presented, as well as temporal and spatial distribution of grain temperature and moisture content. The data sets generated will find application in population modeling and development of integrated pest management systems for stored grain.
