Insect pathogens as biological control agents: Back to the future.
The development and use of entomopathogens as classical, conservation and augmentative biological control agents have included a number of successes and some setbacks in the past 1years. In this forum paper we present current information on development, use and future directions of insect-specific viruses, bacteria, fungi and nematodes as components of integrated pest management strategies for ...
متن کاملThe future of microbial insecticides as vector control agents.
Insect vectors of human diseases are subject to diseases of their own caused by viruses, bacteria, fungi, protozoans, and nematodes. Over the past 30 years, many members of these groups have been evaluated as vector control agents, particularly for mosquito control. Most pathogens and nematodes occur primarily in larvae, and are only effective against this stage. The principal candidate control...
متن کاملThe future of insect growth regulators in vector control.
Insect growth regulators (IGRs) are diverse groups of chemical compounds that are highly active against larvae of mosquitoes and other insects. The IGRs in general have a good margin of safety to most nontarget biota including invertebrates, fish, birds, and other wildlife. They are also relatively safe to man and domestic animals. The IGR compounds do not induce quick mortality in the preimagi...
متن کاملEcdysteroids as Insect Control Agents: A New Ecdysteroid from Stem Bark of Vitex canescens
North Bangkok. ** Department of Chemistry, Faculty of Science, Ramkhamhaeng University. Abstract A new ecdysteroid, P5, has been isolated from the stem bark of aged trees (with flower) of vitex canescens. 20-Hydroxyecdysone, makisterone A, 24-epi-makisterone A, and canescensterone have also been isolated from both young trees (without flower) and aged trees (with flower) of vitex canescens. The...
متن کاملModifying insect population age structure to control vector-borne disease.
Age is a critical determinant of the ability of most arthropod vectors to transmit a range of human pathogens. This is due to the fact that most pathogens require a period of extrinsic incubation in the arthropod host before pathogen transmission can occur. This developmental period for the pathogen often comprises a significant proportion of the expected lifespan of the vector. As such, only a...
