Effective vector control, and more specifically mosquito control, is a complex and difficult problem, as illustrated by the continuing prevalence (and spread) of mosquito-transmitted diseases. The sterile insect technique and similar methods control certain agricultural insect pest populations in a species-specific, environmentally sound, and effective manner; there is increased interest in app...

n their continuing battle with more I than 10,000 insect pest species, scient ists and growers in the United S ta tes achieved some striking successes against many pests, mainly with broad-spectrum insecticides. Unfortunately, those pesticides have had detrimental side effects: Pest insects developed resistance to formerly lethal materials; natural enemies of pests were destroyed; previously in...

Most animals, including pest insects, live in an "odor world" and depend strongly on chemical stimuli to get information on their biotic and abiotic environment. Although integrated pest management strategies including the use of insect growth regulators (IGRs) are increasingly developed, most insect pest treatments rely on neurotoxic chemicals. These molecules are known to disrupt synaptic tra...

Phytophagous pentatomid insects can negatively impact agricultural productivity and the brown marmorated stink bug (Halyomorpha halys) is an emerging invasive pest responsible for damage to many fruit crops and ornamental plants in North America. Many phytophagous stink bugs, including H. halys, harbor gammaproteobacterial symbionts that likely contribute to host development, and characterizati...

Mini review Application of RNA interference (RNAi) by feeding to pest management M1 Yuki Maruyama RNA interference (RNAi) is a powerful tool to specifically suppress gene expression in both invertebrates and vertebrates, therefore, it has not only been used widely to study gene function in insects, also thought to be available for application to pest management. However, practical utilization w...

Aphids are a major concern in agricultural crops worldwide, and control by natural enemies is an essential component of the ecological intensification of agriculture. Although the complexity of agricultural landscapes is known to influence natural enemies of pests, few studies have measured the degree of pest control by different enemy guilds across gradients in landscape complexity. Here, we u...

In this paper, we investigate the dynamic behaviors of a Holling II two-prey one-predator system with impulsive effect concerning biological control and chemical control strategy-periodic releasing natural enemies and spraying pesticide at different fixed moment. By using the Floquet theory of linear periodic impulsive equation and small-amplitude perturbation method, we show that there exists ...

sunn pest is considered as the most important insect pest of wheat and barley in iran. different studies have shown that various biotic and abiotic factors affect sunn pest populations. these factors can influence the population density of the pest which in turn can play a role in the control of the pest. in this study the relationship between sunn pest population fluctuations and climatic cond...

Genetically engineered insects are being evaluated as potential tools to decrease the economic and public health burden of mosquitoes and agricultural pest insects. Here we describe a new tool for the reliable and targeted genome manipulation of pest insects for research and field release using recombinase mediated cassette exchange (RMCE) mechanisms. We successfully demonstrated the establishe...

Stored-product insects are a perennial problem in retail stores, where they damage and contaminate susceptible merchandise such as food products and animal feed. Historically, pest management in these stores has relied heavily on chemical insecticides, but environmental and health issues have dictated use of safer methods, and these require better monitoring. A monitoring procedure that employs...
