sublethal effects of two juvenile hormone analogue, flufenoxuron and lufenuron, were evaluated on larval, pupal and adult stages of habrobracon hebetor say under laboratory conditions. dose-response bioassays were carried out on the insect’s immature and adult stages through dipping and contact residue methods. in the sublethal effect tests, field rates (500 ppm) of the two insecticides were em...

Chitin and β-glucan are major cell wall components of Aspergillus spp. We investigated the antifungal activity of chitin synthesis inhibitors nikkomycin Z, polyoxin D, flufenoxuron, lufenuron, and teflubenzuron, alone and combined with the β-glucan synthesis inhibitor caspofungin. Only nikkomycin Z and caspofungin were found to act synergistically. The nikkomycin Z-induced chitin decrease corre...

The onion maggot, Delia antiqua, is a devastating pest of liliaceous crops and current control measures fail to avert pesticide residues, threats to agroecosystem, and costly expenditures. Insect growth regulators (IGRs) are used as trypetid pest chemosterilants for their suppression on adult fertility and fecundity, but their effects on onion flies are unknown. Here, three IGRs (lufenuron, cyr...

The present study aimed to compare between the action of the pyrethroid insecticide lambda-cyhalothrin and the benzoylphenylurea lufenuron on total protein, carbohydrate and lipid content, and on digestive enzymes, transaminases, phosphatases and chitinase activity of Culex pipiens L. late third-instar larvae compared to the control. Both lambda-cyhalothrin and lufenuron significantly reduced t...

Pesticides can negatively affect insect immunity. Although studies show that Formosan subterranean termites, Coptotermes formosanus Shiraki, are resistant to microbial infections, the effects of pesticides on disease resistance is not well studied. In this study, C. formosanus previously fed lufenuron was exposed to each of the three entomopathogenic bacteria, Pseudomonas aeruginosa (Schroeter)...

The present study examined the impact of Lufenuron on biochemical parameters of albino mice.The biochemical parameters such as Alanine aminotransferase (ALT), Aspartate aminotransferase (AST) and Alkaline phosphatase (ALP) and Total protein in serum were observed. The mice exposed with Lufenuron 0.1520 mg/kg) for 30 days. The present study suggests that the level of AST, ALT and ALP were increa...

During the last few years, reports have appeared claiming that lufenuron diminished or even cured dermatophyte infections in cats and dogs. As these observations have a rather anecdotal character leading to some ambiguity in the literature, it was decided to test lufenuron in a generally accepted animal model for dermatomycotic infection. The test was carried out in guinea pigs artificially inf...

Knowledge on side effects of pesticides on non-target beneficial arthropods is a key point in Integrated Pest Management (IPM). Here we present the results of four experiments conducted in vineyards where the effects of chlorpyrifos, thiamethoxam, indoxacarb, flufenoxuron, and tebufenozide were evaluated on the generalist predatory mites Typhlodromus pyri Scheuten and Amblyseius andersoni (Chan...
