ABSTR ACT: In a laboratory investigation, the effect of natural sunlight and UV light exposure on dissipation of fipronil insecticide from two soils (clay loam and sandy clay loam) and the effect of pH on the persistence of fipronil in aqueous medium were studied. Dissipation of fipronil insecticide under sunlight followed biphasic first order kinetics in both soils. The half-life of the insect...
chemical control against overwintered adults of sunn pest eurygaster integriceps put. mostly has low efficacy. today using insecticides and formulations that have durable toxicity on overwintered adults is more approved, because this strategy can reduce treated area against new generation. this research was conducted with six treatments and four replications in randomized complete block design ...
Toxicity of a phenyl pyrazole insecticide, fipronil, to 4th-instar larvae of 6 species of colonized mosquitoes (Aedes aegypti, Ae. albopictus, Ae. taeniorhynchus, Anopheles quadrimaculatus, Culex nigripalpus, and Cx. quinquefasciatus) and 2 species of field-collected chironomid midges (Chironomus crassicaudatus and Glyptotendipes paripes) was evaluated in the laboratory. All mosquito species we...

Introduction: Application of insecticidal baits is one of the most common and effective strategies for controlling German cockroach, (Blattella germanica L.) The current study was designed to investigate the susceptibility level of German cockroach to fipronil and imidacloprid gel baits in laboratory situation and to recommend its usage in Iran. Methods: This experimental study was conducted o...
Fipronil is a widely used phytosanitary product and insecticide for pets. In the rat, fipronil can disrupt thyroid function by decreasing plasma concentrations of total thyroxine (T4) likely through increased T4 clearance. However, the mechanism of fipronil action on thyroid function remains unclear. The goals of the present study were to evaluate the effects of fipronil on thyroid hormone (TH)...
vocabulary as a major component of language learning has been the object of numerous studies each of which has its own contribution to the field. finding the best way of learning the words deeply and extensively is the common objective of most of those studies. however, one effective way for achieving this goal is somehow neglected in the field. using a variety of activities such as games can r...
control of insect pests of agriculture, economic, and medical importance usually focuses on the use of insecticides. the susceptibility levels of eleven strains of german cockroaches, blattella germanica (l.), were compared with a standard susceptible strain against permethrin and fipronil. the strains were collected from nine infested students’ dormitories and two infested hospitals in tehran,...
The insecticidal activity of a cockroach gel bait containing a chitin synthesis inhibitor, noviflumuron, was evaluated using laboratory and field strains of the German cockroach, Blattella germanica (L.). Noviflumuron gel bait (0.01-5 mg g(-1)) caused > or = 90% nymphal mortality to laboratory and field strains of B. germanica in choice tests after 11 and 19 days of continuous exposure respecti...
