Helicoverpa spp. and mirids, Creontiades spp., have been difficult to control biologically in cotton due to their unpredictable temporal abundance combined with a cropping environment often made hostile by frequent usage of broad spectrum insecticides. To address this problem, a range of new generation insecticides registered for use in cotton were tested for compatibility with the assassin bug...

Abstract Background Antibiotic resistance is on the rise, and new antibiotic research has slowed in recent years, necessitating discovery of possibly novel microbial resources capable producing bioactive compounds. Microbial infections are gaining to existing antibiotics, emphasizing need for medicinal molecules be discovered as soon possible. Because possibilities isolating undiscovered actino...

background : according to the national strategy plan on monitoring of insecticides resistance, this study was carried out to determine the base line susceptibility of the culicidae mosquitoes to the who-recommended insecticides in an endemic focus of malaria in southeastern iran. methods : larval collection was carried out by dipping method and adult collection occurred by suction tube from jan...

Insecticides are one of the major tools for controlling vector populations and for reducing the transmission of human pathogens. However, there are few new insecticides being developed and marketed for vector control. Herein, we report on the toxicity of six novel insecticides to both adult and larval Aedes aegypti (L). and the toxicity of three novel insect growth regulators (IGRs) to larvae. ...

A series of bioassays were conducted to determine the relative toxicities and residual activities of insecticides labeled for use in blueberry (Vaccinium corymbosum L.) on natural enemies, to identify products with low toxicity or short duration effects on biological control agents. In total, 14 insecticides were evaluated using treated petri dishes and four commercially available natural enemi...

Triatoma infestans (Klug) is the main vector of Chagas disease, which is a public health concern in most Latin American countries. The prevention of Chagas disease is based on the chemical control of the vector using pyrethroid insecticides. In the last decade, different levels of deltamethrin resistance have been detected in certain areas of Argentina and Bolivia. Because of this, alternative ...

Four insecticides were tested for their suitability to an integrated pest management program of woolly apple aphid (WAA). The tested insecticides were imidacloprid, pirimicarb, cartap and petroleum oil. Three indices were developed to determine the degree of selectivity of studied insecticides and to determine their suitability to WAA IPM program. WAA index used to measure the efficacy of the i...

BACKGROUND Neonicotinoid insecticides are generally efficacious against many turfgrass pests, including several important phloem-feeding insects. However, inconsistencies in control of western chinch bugs, Blissus occiduus, have been documented in field efficacy studies. This research investigated the efficacy of three neonicotinoid insecticides (clothianidin, imidacloprid and thiamethoxam) aga...
