“…Levels of constitutive benzoquinones in T. castaneum increase during the first 30 d of adult life and then remain constant (Wirtz et al, 1978;Unruh et al, 1998). Therefore, the observed pattern of volatile emission was surprising; benzoquinones increased for the first week (Faustini and Burkholder, 1987) but then decreased for the following two weeks, before increasing exponentially. An explanation for this pattern should be sought through further experimentation, but the pattern was not related to immature individuals in the diet and did not match the amount of benzoquinones sequestered inside the beetles (Unruh et al, 1998).…”

“…There are at least two isomers of DMD that are biologically active, with an 8:2 mixture of the 4R,8R-and 4R,8S-mimicking the aggregation pheromone of T. castaneum (Suzuki et al, 1984). Previous research has examined the relative emission of these chemical components related to density (Faustini and Burkholder, 1987), but the behavioral response and a more precise measure of emission over time have not been addressed.…”

Density-Related Volatile Emissions and Responses in the Red Flour Beetle, Tribolium castaneum

Intraspecific attraction depends both on the cues provided by the attracting individual and the response of the attracted individual. These attracting cues are related not only to current conditions, but also are a reflection of individual and population life history. These relationships were examined by placing red flour beetle, Tribolium castaneum (Herbst.), adults in flasks at increasing densities and monitoring the changes in volatile chemical emission over time. Only certain chemicals were quantified: methyl benzoquinone, ethyl benzoquinone and 4,8-dimethyldecanal, all of which are known to impact the biology of T. castaneum. The flasks were used as sources for both quantification of the chemicals and for bioassays. Additional bioassays were conducted with synthetic 4,8-dimethyldecanal, a known aggregation pheromone component, to evaluate attraction with respect to population density. Tribolium castaneum density affected both the release of volatile chemicals and the responses of conspecifics to those chemicals. The results indicated that while there were important effects of beetle density on chemical emission and response, none of the chemicals evaluated emerged as promising synergists to the current aggregation pheromone 4,8-dimethyldecanal. The benzoquinones released in response to stress and density acted as anti-aggregation pheromones along with their accepted defensive function.

“…Orzaephilus, Prostephanus, and Tribolium) aggregate at food and oviposition site resources in response to pheromones released by pioneer males (69,168,245). When resources become crowded, thereby increasing the risk to progeny, adults or larvae release other pheromones that repel would-be colonizers (69,168,245). Although fitness costs associated with larval crowding in these genera have been well studied, benefits from grouping, other than enhancement of the probability of frequent copulation and resultant higher fecundity (see e.g.…”

Groups of two or more consexual conspecific adults of many kinds of nonsocial insects have been observed to form at feeding, mating, ovipositional, or sheltering sites. Conversely, adults of these same insects have been observed to avoid joining consexual conspecifics (or their progeny) and to place themselves (or their progeny) at some distance that results in spacing. Examples from various taxa illustrate that mechanisms underlying joining or avoidance behavior differ among species, as do types of benefits and costs to individuals who decide to join or avoid others. Moreover, within a given species, the decision to join or avoid others can be affected markedly by the physiological and informational state of the individual and by contextual response thresholds to resource availability. Decisions that benefit the individual may or may not affect the group in terms of total reproductive output.

“…There will be an advantage to insect that commence dispersion before condition deteriorate too far (temperature too high or too low, moisture too high or too low, density too low or too high), thus improving their chances of finding more suitable conditions. Dense populations of T. castaneum release benzoquinones causing the beetles to migrate from the crowded area [20]. Movement of grain results upward movement of Sitophilus oryzae [6,42].…”

The progress in understanding the stored grain ecosystem is reviewed. Succession of insects, insect movement and distribution, interaction among insects and microflora, and the development of hot spots inside stored grain ecosystems are evaluated. Based on these case studies, we examined the understanding of the stored grain ecosystem from the view of ecosystem approach. To understand the storage grain ecosystem, integration of the parts (the collected data under small scale laboratory conditions) into a usable whole (the entire grain storage ecosystem) is required. To verify the synthesised whole, both small and full scale tests are required. To manage the stored grain ecosystem, understanding the ecosystem and application of ecosystem approach are the keys.
