“…However, S. cerealella can penetrate intact rice hulls . Once the hull is removed during the initial milling process, the rice is classified as brown rice, and the loss of the protective hull facilitates infestation by stored product insects (Sittisang and Imura, 1987). In addition, the red flour beetle, Tribolium castaneum (Herbst), a cosmopolitan grain pest, can readily feed and develop on brown rice (Kavallieratos et al, 2015).…”

Hard red winter wheat, brown rice, rough rice, and corn were treated with the insect growth regulator (IGR) methoprene at rates of 1.25 and 2.5 ppm, held for 24 months at ambient conditions in buckets on the floor of a grain bin, and sampled every two months. Bioassays were done by exposing 10 mixed-sex adults of Rhyzopertha dominica (F.), the lesser grain borer, and Tribolium castaneum (Herbst), the red flour beetle, on wheat, R. dominica and Sitotroga cerealella (Oliver), the Angoumois grain moth, on brown rice and rough rice, and T. castaneum and S. cerealella on corn. Sample size for all commodities was about 80 g, and these samples were held for 3 months at 27°C-60% r.h. Both rates of the IGR completely suppressed adult progeny development of R. dominica with little resulting feeding damage, sample weight loss, or insect damaged kernels (IDK). Some adult progeny production of S. cerealella and resulting IDK occurred at both rates on rough rice, brown rice, and corn, but was far less than in untreated controls. There was little adult progeny production but some feeding damage caused by larval T. castaneum in the treated wheat and corn but again far less than in untreated control. Allowing continual exposure of parental adults on grains treated with an IGR, rather than exposing those parental adults for a short time period, may give more accurate evaluations of residual efficacy. Results show that methoprene used as a grain protectant will give residual control of stored product beetles for 24 months, but complete control of S. cerealella may require inclusion of a contact insecticide.

“…When the rough rice hull is removed, the brown rice is vulnerable to attack by neonate R. dominica . Progeny production in brown rice is consistently greater than progeny production in rough rice of the same variety ( McGaughey 1970 ; Sittisuang and Imura 1987 ).…”

Several physical and chemical attributes of rice were evaluated to determine which character would be best to use to assess multiple rice varieties for resistance to the lesser grain borer, Rhyzopertha dominica (F.). Laboratory tests were conducted on single varieties of long-, short-, and medium grain-rice to develop procedures and methodologies that could be used for large-scale screening studies. Progeny production of R. dominica was positively correlated with the percentage of broken hulls. Although kernel hardness, amylose content, neonate preference for brown rice, and adult emergence from neonates varied among the three rice varieties tested they did not appear to be valid indicators of eventual progeny production, and may not be useful predictors of resistance or susceptibility. Soundness and integrity seem to be the best characters to use for varietal screening studies with R. dominica.

“…Brown rice is susceptible to attack by neonate R. dominica if the rough rice hull is removed. Progeny production is consistently greater in brown rice than in rough rice (Sittisuang & Imura 1987). Variability in sorghum resistance to storage insect pests has been related to the integrity of the hardness, hull and thickness of the endosperm (Throne et al 2000).…”

Storage grain infestation is a critical problem, with insect pests and rodents causing economic losses and reductions in the quality of food grains and food products. It has been assessed as affecting 9% of goods in developed countries and more than 20% of goods in developing countries. The chemical insecticides used for storing products protect against insect pests, but introduce hazards associated with handling insecticides and the residues on food, which threaten nontarget organisms, and so represent a serious problem to the environment. Biorational methods are low risk, are obtained from animals, plants, bacteria and some minerals, and are segregated into microbial, plant‐associated protectant and biochemical substances. This method encompasses temperature management, modified atmospheric storage, ionizing irradiation, the mixing of inert materials, pheromone traps, botanicals, insect growth regulators, entomopathogens and host plant resistance. Biorational methods have emerged as alternative or supplemental pest control methods. Biopesticides would help in preventing the use of large quantities of pesticides across the globe, thus providing residue‐free food and a safe environment for living. Further investigation is needed to integrate these elements to enhance the efficacy, minimize the losses and diminish the reliance on pesticides for the preservation of stored commodities.
