Insect pests of stored products are organisms that damage agricultural products in fields or warehouses and cause a lot of product loss. For this reason, it is an important problem to protect the products in warehouses after harvest. Producers and researchers try many chemical methods to prevent this damage in warehouses. However, in recent years, as the harm of these chemicals to the environment and mammalian health has been understood, researchers have been trying to find different methods. Insects develop more and more resistance to these chemicals, as they adapt to the environment very quickly. For this reason, the biology and physiology of insects must be well known before the fight against these insects. The better the biology and physiology of these insects are known, the more new methods can be developed for integrated control methods against this insect. Since insects are poicliothermic, that is, dependent on changes in environmental temperatures, temperature is very important in their development. Another factor affecting the developmental stages of the insect is nutrient. Temperature and food together can limit insect developmental stages. While high temperatures prolong developmental stages, they can have the opposite effect on longevity. Or, insects feeding on poor quality nutrient can affect egg size, adult size, or horn and cuticle development, as seen in some Coleopters. In this review study, the effects of temperature and nutrient on the biology and physiology of storage product pest Coleopters were evaluated.

“…Although O. surinamensis did not produce eggs on maize Flour, its larval developmental time was shorter on maize Flour (16.6 d) compared to Oat flakes (20.3 d) and whole barley Flour (19.2 d) (Nika et al 2020). Furthermore, in the research of Hashem et al (2021), the performance of the insect was better in rice, followed by sesame and dry dates, while according to Awadalla et al (2021) the highest survival and adult emergence were noted when fed on fruits and nuts, except raisin, and the corresponding lowest on legume seeds and soybean.…”

Developmental ability of Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae) was examined on six different sorghum milling fractions: Bran, Shorts, Cgrits, Fgrits, Red dogs, Flour, and also on a standard diet of Oat Flakes. For this purpose, a 1-day-old egg was placed in a vial containing 1 g of one of the sorghum fractions and exposed to three temperatures: 25, 30, or 32°C. All vials were checked daily for pupal and adult emergence and mortality of immatures. The developmental time was significantly affected by the type of sorghum fraction. After two weeks, for most of the temperatures examined, the longest developmental times in most cases for both pupation and adult emergence were observed in Flour and Oat flakes. Increasing the temperature from 25 to 30 accelerated the development, while adult emergence time did not differ between 30 and 32°C for all fractions except Flour. Egg mortality ranged from 11 to 78%, while larval and pupal mortality ranged from 0 to 22 and 0 to 45%, respectively for all sorghum fractions and different temperatures tested. Moreover, the mean overall immature mortality occurred at 30°C was 49.2, 39.7, and 65.1% at 25, 30, and 32°C for all the diets examined. The findings of the present work show that O. surinamensis can develop and survive in sorghum milling fractions and that the optimal temperatures for growth enhancement are 30 and 32°C. The temperatures within sorghum milling facilities could support O. surinamensis development on milling fractions if they are not addressed through phytosanitary measures.

BACKGROUNDMortality caused by various pyrethroids, and neonicotinoids has been studied for stored‐product insects in the past, yet limited information exists on the sublethal effects they can induce to Oryzaephilus surinamensis. In the current study, the sublethal effects of deltamethrin, λ‐cyhalothrin, α‐cypermethrin, etofenprox, and the mixture of acetamiprid with d‐tetramethrin and piperonyl butoxide on the mobility of O. surinamensis in the presence or the absence of a food source was investigated.RESULTSLethal concentrations (LCs) were lower for deltamethrin, α‐cypermethrin, and λ‐cyhalothrin (LC10 = 0.000233, 0.000211, and 0.000271 mg active ingredient (a.i.) cm−2, LC30 = 0.000413, 0.000398, and 0.000447 mg a.i. cm−2, respectively), followed by etofenprox, and the mixture of acetamiprid with d‐tetramethrin and piperonyl butoxide (LC10 = 0.00228 and 0.003267 mg a.i. cm−2, LC30 = 0.00437 and 0.01188 mg a.i. cm−2, respectively). Deltamethrin and λ‐cyhalothrin negatively impacted adult walking behavior, increasing stop durations compared to controls. Adults exposed to LC10 and LC30 of λ‐cyhalothrin, and LC30 of deltamethrin exhibited prolonged periods on their backs compared to the remaining treatments and the controls. The α‐cypermethrin LC30‐exposed adults exhibited significantly shorter walking and stopping durations than controls but demonstrated prolonged climbing on the arena walls compared to adults exposed to the remaining a.i. and the control. A similar trend was observed for etofenprox.CONCLUSIONSUnder sublethal concentrations, λ‐cyhalothrin and deltamethrin increased stop intervals and reduced the duration of climbing attempts of O. surinamensis versus α‐cypermethrin. These findings advance comprehension of the underexplored sublethal impacts of the tested a.i. on O. surinamensis adults, holding potential for leveraging insecticide‐induced behavioral effects to enhance warehouse pest management. © 2024 The Author(s).
