Pestiferous cockroach species are associated closely with humans and are important from medical and public health points of view. Conventional insecticides have been used widely to control cockroaches which have developed resistance to these compounds. Thus, interest has again centered on lesser-used compounds such as boric acid. Boric acid has been used as(More)
The effects of the insect growth regulator diflubenzuron (DFB) were observed on the larval-larval and larval-pupal moulting cycles of Tenebrio molitor, after treatment at ecdysis. In both cases, the first parts of the cycles, from ecdysis to apolysis, were apparently not affected, but the pharate periods were lengthened; treated animals were generally(More)
Acetamiprid was incorporated into the diet at 2% dose corresponding to the LD50 and orally administrated to newly emerged adults of the German cockroach Blattella germanica and investigated on acetylcholinesterase activity and cuticular hydrocarbons profil. Acetylcholinesterase specific activity was determined on adult males and females after 24, 48 and 72(More)
Recently, dimilin was found to be effective on Culex pipiens (Diptera: Culicidae). Although considerable research has evaluated the efficacy of diflubenzuron, a benzoylphenylurea derivative, against target pest populations, impacts of this compound on nontarget organisms are comparatively unknown. Therefore, this study evaluate toxicity of dimilin (25%(More)
Experiments were conducted to assess the effect of gibberellic acid (GA3), a plant growth regulator, on Locusta migratoria migratoria fifth instar larvae. Newly emerged larvae were exposed to various concentrations of GA3 administered by topical application or by forced ingestion. Results showed that treated insects exhibited toxic symptoms with a(More)
The secondary effects of conventional insecticides on the environment, vertebrates and beneficial organisms have caused a move to the use of more target-specific chemicals such as insect growth regulators. Halofenozide (RH-0345) is a novel nonsteroidal ecdysteroid agonist that induces a precocious and incomplete moult in several insect orders. In the(More)
Donax trunculus is the most consumed bivalve by the local population of the Northeast Algeria for its nutritional value. Therefore, the aim of the current study was to determine the effects of cadmium (Cd), a known toxic metal, on the alterations in main essential omega-3 fatty acids, i.e., eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid(More)
RH-0345 (halofenozide), a bisacylhydrazine derivative, is a nonsteroidal ecdysteroid agonist that mimics the action of the moulting hormones, while KK-42, an imidazole compound, is a potent inhibitor of ecdysteroid biosynthesis. Recent experiments with Tenebrio molitor suggested that the reduction of ecdysteroid titer, leading to a reduction of reproductive(More)
Diflubenzuron (Dimilin 25WP) is an insecticide of the class of benzoylphenylurea (BPUs) and is widely used in the control of insect pest in agriculture and forestry. Typically, these chemistries prevent the moulting process by inhibiting chitin formation and thereby causing abnormal cuticular deposition and abortive moulting in insect and crustacean(More)
Tebufenozide, a dibenzoylhydrazine insect growth regulator, was applied topically (1 microg/insect) on female adults of the German cockroach Blattella germanica and its effects on ovarian measurement and proteins contents were investigated during the first gonadotrophic cycle (0, 2, 4 and 6 days). Dissection of treated females showed a clear reduction in(More)
