sunn pest (eurygaster integriceps put.) is one of the major pests of wheat in iran. identification of resistantcultivars is an effective integrated pest management (ipm) strategy. to identify the genetic response of wheat and triticale to sunn pest, and determine the relationship between resistance and morpho physiological traits, eight bread wheat breeding lines/cultivars, four durum wheat lin...

Stored product insects cause millions of dollars per year in losses in stored wheat. Traditionally, storedproduct pest management has relied on chemicals to control insects. In some cases, pest management has been improved by applying chemicals only when needed. An increasing effort is being made to reduce or eliminate pesticide residues in the food supply. This trend has increased since the in...

The sterile insect technique (SIT) is an environmentally friendly method of pest control in which insects are mass-produced, irradiated and released to mate with wild counterparts. SIT has been used to control major pest insects including the pink bollworm (Pectinophora gossypiella Saunders), a global pest of cotton. Transgenic technology has the potential to overcome disadvantages associated w...

Pest insects pose a significant threat to food production worldwide resulting in annual losses worth hundreds of billions of dollars. Pest control attempts to prevent pest outbreaks that could otherwise destroy a sward. It is good practice in integrated pest management to recommend control actions (usually pesticides application) only when the pest density exceeds a certain threshold. Accurate ...

certain compounds of plants such as essential oils, with insecticidal properties have been considered as alternatives to chemical pesticides for pest control. this study reports the fumigant toxicity of citrus reticulata blanco (rutaceae) peel essential oils against stored-product insect pest, red flour beetle, tribolium castaneum herbst (tenebrionidae) adults. experiment was carried out at 27 ...

ABSTRACT- Several species of aphids cause severe damage to citrus in the north of Iran. Predatory insects play an important role in biological control of the pests in citrus orchards. In this study, potential predatory insects of citrus aphids, Aphis spiraecola, A. gossypii and Toxoptera aurantii, were identified and their seasonal population dynamics...

The relationship between silvicultural practices, e.g. thinning, and pest organisms (insects and diseases) has been investigated extensively in pine species but to a lesser degree in hardwoods. Of critical interest is the potential negative impact to the residual stand resulting from insect damage and diseases that develop as a consequence of silvicultural practices. This is especially true wit...

Pesticides are often considered a suitable solution for controlling pests. However, the use of chemicals is very costly, and their residues have always the potential to pollute soil, air, and ground water and also pose significant risks to the natural ecosystems and nontarget organisms. Considering all these, irradiation could offer substantial and charming option for eliminating the export com...
