The Effect of Temperature and Nutrient on Developmental Biology and Physiology of Stored-Product Species of Coleoptera

Abstract

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.
