“…Jian et al [37] found that adults of C. ferrugineus introduced in a 0.6-m diameter and 1.12-m high wheat column had a similar distribution with those introduced in 0.1 9 0.1 9 1.0 m columns. Inside elevator in the USA, the numbers of insects generally tended to decrease with the depth below the grain surface [23,24,52]. This suggests that insects infest wheat stored at the elevator after it has been loaded into bins and then disperse down into the grain [23].…”

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.

“…The 9-fold difference in densities between adult and larval stages was small compared with the 37-fold difference in the number of sounds they produced. In another study that compared ratios of immatures to adults, mean immature to adult ratios were 488.5, 85.9, 71.8, 56.6, 55.8, 17.8, 11.2, 9.7, 5.5, 5.2, 4.4, 3.0, 1.9 in wheat samples from a grain elevator bin [ 223 ]. Thirteen locations had immatures but no adults.…”

Acoustic technology provides information difficult to obtain about stored insect behavior, physiology, abundance, and distribution. For example, acoustic detection of immature insects feeding hidden within grain is helpful for accurate monitoring because they can be more abundant than adults and be present in samples without adults. Modern engineering and acoustics have been incorporated into decision support systems for stored product insect management, but with somewhat limited use due to device costs and the skills needed to interpret the data collected. However, inexpensive modern tools may facilitate further incorporation of acoustic technology into the mainstream of pest management and precision agriculture. One such system was tested herein to describe Sitophilus oryzae (Coleoptera: Curculionidae) adult and larval movement and feeding in stored grain. Development of improved methods to identify sounds of targeted pest insects, distinguishing them from each other and from background noise, is an active area of current research. The most powerful of the new methods may be machine learning. The methods have different strengths and weaknesses depending on the types of background noise and the signal characteristic of target insect sounds. It is likely that they will facilitate automation of detection and decrease costs of managing stored product insects in the future.

“…Stored grain insects are one of the main causes of stored grain losses which may reach 9% in developed countries and 20% or more in developing countries (Phillips & Throne, 2010). Khabra beetle Trogoderma granarium Everts is one of the most important stored grain pests, the most dangerous and resistant to insecticides (Mahmood et al, 1996). It adapts to various environmental conditions, where larvae can survive for 23 months without food and enter into dormancy until the food is available.…”

The study showed that the highest activation percentage of the insecticides (Spinosad, Emamectin and the mixture of the insecticides) were obtained when mixed with silica gel for the larvae grown on the corn (2.266, 1.255 and 1300 respectively), while the lowest activation percentage (Antagonism) was recorded for the mixture of each of the Spinosad and Emamectin separately with the gypsum of the larvae grown on the wheat giving 0.776 and 0.989, respectively. The highest of synergism percentage was for silica gel when mixed with each of Spinosad, Emamectin and the mixture of insecticide against the larvae which grown on corn reached 2.014, 1.178 and 1.256 respectively; the lowest of synergism percentage was for gypsum when mixed with the Spinosad and the insecticide mixture against larvae grown on the wheat, which reached 0.454 and 0.918 respectively, while the ratio was 0.841 for the Emamectin insecticide when mixed with the limestone against the larvae which grown on wheat. For the percentage of potentiation, the study showed that the treatment of larvae grown on wheat and corn which treated with a mixture (silica gel and Spinosad insecticide) gave the highest percentage of the potentiation of the pesticide reached 0.41 and 0.252 respectively, and the lowest potentiation percentage of larvae on wheat and maize was recorded for gypsum with the mixture of insecticides reaching 0.082 and 0.016 respectively.
