“…Several studies recommend waiting until September for initial cooling at 12Ð15ЊC (Storey et al 1979, Noyes et al 1987, Cuperus et al 1990, partly because of the belief that high harvest temperatures will inhibit insect population growth (Noyes et al 1987). However, several Þeld-sampling studies have shown that insect pests can be found in stored wheat during the summer (Cuperus et al 1986, Reed et al 1991, Dowdy and McGaughey 1994.…”

Simulation studies were conducted to determine temperature accumulations below defined thresholds and to show the impact of controlled aeration on populations of the rusty grain beetle, Cryptolestes ferrigineus (Stephens), a major secondary pest of stored wheat, Triticum aestivum (L.). Recorded data from weather stations in Texas, Oklahoma, Kansas, eastern New Mexico, and eastern Colorado (356 total) were used to determine hours of temperature accumulation below 23.9 degrees C in June and July, 15.6 degrees C in September and October, and 7.2 degrees C in December. At an airflow rate of 0.0013 m3/s/m3 (0.1 cubic ft3/min/bu), which requires 120 h of temperatures below the specified threshold to complete an aeration cycle, summer cooling at 23.9 degrees C in bulk-stored wheat could be completed throughout the hard red winter wheat zone except for extreme southern Texas. An early-autumn cooling cycle at 15.6 degrees C could not be completed throughout most of Texas and Oklahoma before the end of September. The late-autumn cooling cycle could be completed in all states except Texas by the end of November. Five geographic regions were delineated and the times required for completion of the summer, early-autumn, and late-autumn cooling cycles within each region were estimated. Population growth of the rusty grain beetle was modeled for San Antonio, TX; Abilene, TX; Tulsa, OK; Topeka KS; and Goodland, KS, by predicting the numbers of adults in the top, outer middle, outer periphery, and the center of the bin during a 1-yr storage season. Populations of C. ferrugineus in San Antonio and Austin were predicted to exceed the Federal Grain Inspection Service (FGIS) threshold of two beetles per kilogram of wheat in all four levels of the bin during late autumn, decline during the winter, and increase the following spring. In Midland, TX, and Oklahoma City, OK, populations were predicted to exceed the threshold only in the top and outer middle of the bin, whereas populations in the Kansas locations were not predicted to exceed the threshold at any time.

“…As temperatures begin to decline in autumn, stored wheat can be cooled through low-volume aeration with ambient air (Cuperus et al 1990). In the absence of aeration, large bulks of wheat will stay warm throughout the winter (Schmidt 1955).…”

“…Indian meal moth, P. interpunctella, is distributed world-wide and is a serious stored-product pest of grain and seeds (Lecato 1976;Cuperus et al 1990;Doud and Phillips 2000; as well as flour and other milled products (Lecato 1976). They attack a wide variety of dried fruits and nuts (Johnson et al 1992;Shojaad-dini et al 2005).…”

Fumigant toxicity of the essential oil derived from Carum copticum C.B. Clarke (Apiaceae) were assessed against growth stages of Indian meal moth, Plodia interpunctella (Hubner) (Lepidoptera: Pyralidae). Seeds of the plant were collected from Tehran, Iran and hydrodistilled to extract their essential oil. The essential oil was analyzed by GC and GC-MS. Thymol (64.51%), γ-terpinene (17.52%) and p-cymene (16.16%) were the main components among the eight constituents characterized in the oil, representing 98.19% of the total components detected.All bioassay tests were conducted at 25 ± 1°C, 65±5% RH and photoperiod of 16:8 h (light:dark). After These findings indicated that essential oil from seeds of C. copticum could have potential of practical value for application in management of the Indian meal moth in storage.

“…The influence of trap design has been evaluated for many herbivorous pest species, including codling moth and oblique-banded leafroller [119], velvetbean caterpillar [120], fall armyworm [120][121][122], corn earworm [123][124][125], European corn borer [126], black army cutworm [127], maize stalk borer [128], Heliothis virescens [129,130], Mexican rice borer [737], Ephestia kuehniella [132]; hickory shuckworm [733], apple leafroller [134], Lepidopteran fruit pests [735], the noctuid Mythimna convecta [136], sweet potato weevil [137], bark beetles and other forest Coleoptera [138,139], stored products insects [140][141][142][143][144][145][146][147][148], Mediterranean fruit fly [149] . A grain probe trap for stored products insects has been designed as a long cylinder that can easily be inserted into the grain, with small holes just large enough to allow insects (but not grain) to enter the cylinder [158].…”

Chemical communication is important in the life cycles of many insect species, principally for the location of mates and food. Structural identification and synthesis has been carried out for many semiochemicals, and a number of techniques have been developed to use these compounds as components of integrated pest management (IPM) programs. Semiochemicals have two main uses in IPM programs: monitoring insect pest populations and preventing agricultural damage by interfering with insect behavior. Pheromones are perhaps the most widely exploited semiochemicals at present, but recent efforts have extended increasingly to the identification and use of compounds involved in interspecific exchange of information as well.The use of semiochemicals to manipulate insect behavior has proved to be one of the most useful components of integrated pest management (IPM) programs. Semiochemicals are compounds that are emitted or displayed by one organism and that affect the behavior of another organism [/]. Perhaps the most important semiochemicals used by insects are those involved in locating mates and food, and at present these are the kinds of semiochemicals most widely exploited for insect control. Semiochemicals with many other kinds of ecological roles have also been characterized in insects, such as compounds that function as warnings, or compounds that mediate the collective activity of many partners in completing large tasks. A number of major reviews of the use of semiochemicals in IPM programs have appeared [7][8][9], as well as a critical review of semiochemical utility in general [10], An extensive list of companies that offer semiochemical lures, traps designed for semiochemical monitoring, and commercial systems for behavioral pest control has been compiled by Inscoe [11].Practical applications of semiochemicals in agriculture fall into two main categories, population monitoring and behavioral pest control. The main use at present is in monitoring insect pests with traps baited with semiochemicals, as a part of making decisions about pesticide application or other control techniques. A second use of semiochemicals is the direct prevention of insect damage by a variety of techniques, including the placement of a large number of semiochemical sources that disrupt the behavior of the insects, mass trapping, attracticides (insecticide lures), and enhancement of parasitoid activity.
