“…A similar result was reported by Suleiman et al (2015) and Keba and Sori (2013) who concluded that small grains like popcorn, which are hard and compact, lead to a resistance to infestation by S. zeamais. For S. oryzae, grain hardness was reported as the main resistance parameter (Bamaiyi et al, 2007). Previous research groups are studying S. zeamais and S. oryzae, while we observed the same pattern in S. granarius.…”

Storage pests are pests adapted to living indoors, where their entire life cycle occurs on stored agricultural products.Nowadays, insects within storage facilities are the main problem in the storage process. Storage systems such as silos, warehouses, and containers are perfect habitats for insects that feed on stored food because they are protected from weather extremes, have unrestricted access to large food sources, and can live continuously for long periods of time. The objective of this study was to determine the intensity of damage by granary (Sitophilus granarius L.) and maize (Sitophilus zeamais Motsch.) weevils on field maize and popcorn and their biological potential over 20 weeks of the storage process.During the study, physical properties of maize (weight, hectolitre weight, moisture and sample weight) and changes in population density of weevils were measured. The results showed differential susceptibility of maize hybrids to weevil feeding. No differences were found between weevil species in terms of the damage they caused. Popcorn does not favor weevil feeding, resulting in low grain damage and high mortality rates for both weevil species. In contrast to popcorn, field corn favors both weevil feeding and weevil reproductive potential, ultimately decreasing grain mass and quality and making it unsuitable for human and livestock consumption. More susceptible field maize can be selected for shorter storage time and thus faster delivery to market.

“…In Indonesia, rice is the main ingredient that supports the population. The process of storing rice can be damaged by infestations of pests and impact to economic losses, among these are Sitophilus oryzae, S. zeamais, Sitotroga cereallela, Rhyzopertha dominica, Oryzaephilus surinamensis (Ashamo, 2009;Astuti et al, 2013;Astuti, Mario, & Widjayanti, 2018).…”

The stored rice is often damaged by storage pests. As an important storage pest, Sitophilus oryzae causes significant weight loss on stored rice. The objective of this research was to evaluate the susceptibility of four rice types on Sitophilus oryzae. The research was conducted in Plant Pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, Universitas Brawijaya from May to September 2017. There were four rice types i.e. Brown rice (Diamond variety), Milled rice (Ciherang variety), Black rice (Watudodol variety), and Red rice (BWI-1 variety). Dobie's Index of Susceptibility was adopted to categorize each rice type. In addition, the Analysis of Variance and Tukey HSD were used to compare the differences between four rice types at α < 0.05. Based on the Susceptibility Index, milled rice was categorized as rice resistant to S. oryzae, while black, brown, and red rice were moderate resistant. The resistance of rice varieties to S. oryzae is influenced by feed quality factors i.e. the adequacy and balance of nutrients, especially ash and fat.

“…Efforts have been made to identify traits that contribute to bruchid resistance in pigeonpea, such as reduction in insect oviposition and adult insect emergence due to the physical and chemical characteristics of the plant host (Fitzner et al 1985;Bamaiyi et al 2000), however information on seed traits conferring bruchid resistance in pigeonpea remains limited. Majority of studies have concentrated more on field than storage.…”

The present study intends to screen 52 pigeonpea genotypes for bruchid infestation under controlled conditions using no-choice assay. The results revealed significant differences among the genotypes considering parameters like growth index (GI), egg numbers and adult emergence. The genotypes viz., ICP 89049, IPA 37 and Dholi dwarf DB had low average values for GI (0.45, 0.48 and 0.48 respectively), number of eggs after 20 days (14.5, 21.5 and 28), and adults emerged after 30 days of oviposition (9.0, 7.0 and 4.5, respectively) when compared to the genotypes Asha (higher GI: 1.10), and IPA 7–6 (having 98.0 eggs after 20 days of incubation). Concerning associations among different traits, the GI had significant positive correlations with number of eggs laid (0.484), and number of adults emerged at 15–30 days (0.638). The GI showed a negative relationship with proportion of seed coat (–0.162) and seed hardness (–0.197). The traits that are less preferred by the bruchids include hard seed with less seed diameter and high proportion of seed coat. The tolerant genotypes viz. ICP 89049, IPA 37 and Dholi dwarf DB identified here could be deployed in breeding programs for reducing post harvest losses in pigeonpea.
