“…Larval, pupal or adult developmental stages of the insect are also effective on this resistance (Irwin & Lee, 2003). They can store different amounts of lipid, protein or carbohydrates according to different developmental stages, or even if they are in the same developmental stage, large pupae, larvae or adult insects store more lipid (Scaccini et al, 2019). Therefore, the insect has more energy reserve and can easily overcome these extreme conditions (Irwin & Lee, 2003;Sinclair & Marshall, 2018).…”

The ever-increasing world population indicates that it is inevitable to consider insects such as Tenebrio molitor, which are used as live feed and even human food in some countries, as an alternative food source. Especially T. molitor larvae are a source of food with high nutritive value for including high lipid and protein. This study seeks answer to the question "will the insect continue to keep its lipid sources during the periods in which it is kept in the cold, or will it continue to use its energy sources since the physiological adaptations it develops are not enough?" The main material of this study was T. molitor cultures. Flour: wheat flour (250 g: 250 g) in a ratio of 1:1 was used as food. 25 g wheat germ and 5 g dry yeast was put in it. Larvae at stages 13-15 th were grouped as control and trial groups and kept for 5, 10, 15 and 20 days at specified temperatures. The weights, total lipid content and percentages of the larvae whose storage period was over were determined. This study evaluates the total lipid amount and percentages of T. molitor larvae stored in refrigerator for different periods. Total lipid amount and percentages of the larvae stored in the cold for 5, 10 and 15 days were found to be higher when compared with the control group. A tendency to decrease was observed in larvae kept for 20 days. As a result, it is recommended for producers not to keep in the refrigerator for more than 15 days. Otherwise, it should be considered that there may be a decrease in important energy and food sources.

“…Temperature influences insects in many ways [25][26][27][28]. For example, while low temperatures increase larval development time and adult longevity in insects, high temperatures can have the opposite effect [25,27]. Insects can tolerate temperature changes within certain limits by changing their metabolic activities, regulating their body temperatures or changing their microhabitats, although it varies according to the species [29,30].…”

“…Changes in ambient temperature can alter the dispersal characteristics of insects and migratory routes, resulting in many pest control problems [36]. Stressful situations such as temperature changes or food shortages in the environment of insects play an important role in their physiological and biochemical reactions [16,27,28,39]. When the temperature increase remains within certain limits, enzymatic activity affects positively [40].…”

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.

BACKGROUND Invasive species threaten the productivity and stability of natural and managed ecosystems. Predicting the spread of invaders, which can aid in early mitigation efforts, is a major challenge, especially in the face of climate change. While ecological niche models are effective tools to assess habitat suitability for invaders, such models have rarely been created for invasive pest species with rapidly expanding ranges. Here, we leveraged a national monitoring effort from 543 sites over 3 years to assess factors mediating the occurrence and abundance of brown marmorated stink bug (BMSB, Halyomorpha halys), an invasive insect pest that has readily established throughout much of the United States. RESULTS We used maximum entropy models to estimate the suitable habitat of BMSB under several climate scenarios, and generalized boosted models to assess environmental factors that regulated BMSB abundance. Our models captured BMSB distribution and abundance with high accuracy, and predicted a 70% increase in suitable habitat under future climate scenarios. However, environmental factors that mediated the geographical distribution of BMSB were different from those driving abundance. While BMSB occurrence was most affected by winter precipitation and proximity to populated areas, BMSB abundance was influenced most strongly by evapotranspiration and solar photoperiod. CONCLUSION Our results suggest that linking models of establishment (occurrence) and population dynamics (abundance) offers a more effective way to forecast the spread and impact of BMSB and other invasive species than simply occurrence‐based models, allowing for targeted mitigation efforts. Implications of distribution shifts under climate change are discussed. © 2022 The Authors. Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.
