“…The Oryzaephilus mixed sex cultures from which frass was collected, typically contained visible fungal growth which may have been used as an additional food source (Sinha 1968). Furthermore, insects (Dolinski and Loschiavo 1973) and mites (Vanhaelen et al 1979) are attracted to fungal volatiles in laboratory bioassays. Metabolites of fungi or yeasts associated with the insect gut may serve as components of an attractive pheromone, as has been found for the Scolytidae (Brand et al 1976;Brand et al 1977).…”

1981. Olfactoq response to beetle-produced volatiles and host-food attractants by Oryzaephilus surinamensis and 0 . mercator. Can. J . Zool. 59: 1980Zool. 59: -1990 A two-choice, pitfall olfactometer which utilizes a petri plate with suspended glass vials was employed to test the response of Oryzaephilus surinamensis (L.) and 0 . mercator (Fauvel) to various volatile stimuli. Male and female beetles of both species were attracted to pentane extracts of Porapak Q trapped volatiles from beetles, frass, rolled oats, and brewer's yeast over a wide range of stimulus concentrations. For both species, male and female frass contained attractive volatiles in addition to those from unused growth medium. This result and the attractiveness of volatiles from beetles suggest that both sexes produce an aggregation pheromone. Additionally, interspecific attraction to beetle and frass volatiles was demonstrated. PIERCE. A. M., J. H. BORDEN et A. C. OEHLSCHLAGER. 1981.

Les males et les femelles des deux esp&ces sont attir6s par des extraits au pentane de produits volatiles retenus sur Porapak Q provenant de coltoptkres, de chiures, d'avoine roulte et de levure de bike, en diverses concentrations. Les chiures des maes et des femelles contiennent des produits volatiles attirants pour les deux es@ces, ce qui vient s'ajouter aux produits volatiles des milieux de croissance inutilists. Ce dsultat et I'attirance des produits volatiles venant des coltopt8res eux-memes permettent de croire que les deux sexes produisent une ph6romone de rassemblement. Les produits volatiles venant des coltopt&res et des chiures ont en outre une attirance intersptcifique.[Traduit par le journal]

“…Surtees (1965) found that the RGB adults accumulated as much in pockets of damp grain as in damp grain infested with mold. Compared with olfactory stimuli, response to humidity (when grain was damp) is a minor factor influencing adult movement, because hygrotactic stimuli inside damp grain do not increase the number of adults moving down (Dolinski and Loschiavo 1973). In stored grain bins, damp grain will likely have a mold infection.…”

“…Toxicity or pathogenicity can be affected by many factors such as temperature, moisture, and kind of substrate. At different grain storage conditions, therefore, responses by RGB adults to fungus-infected grain is different, because this response is influenced by grain moisture content, temperature, fungal species, potency and concentration of the stimulative component, stage of development of the fungus, and the presence of deterrents (Dolinski and Loschiavo 1973).…”

“…It is a short-distance olfactory response when RGB adults in the vicinity of the storages are attracted to grain odor (Barrer 1983). The olfaction system can help adults to detect damp grain pockets infected by fungi (Dolinski and Loschiavo 1973). To find the moldy locations, insects might at first detect the volatiles released from fungi.…”

Detecting and Responding to Resource and Stimulus during the Movements of Cryptolestes ferrugineus Adults

An understanding of insect movement and distribution within grain bulks is essential to effectively control insect pests. The aim of this review was to (1) identify the major and minor factors influencing the movement of adults of Cryptolestes ferrugineus and to (2) analyze their ability of resource detecting and cue orienting. Their response to major and minor environmental factors was related with the general features of the grain storage environment, their development requirement, and their ability of cue orienting and detecting. Their movement inside stored grain bins and in small-scale chambers was compared. Incompleteness of our current knowledge regarding their movement and cue detection under multi-factors is the main reason why we cannot predict yet their dispersal and distribution inside granaries accurately.

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.
