Greenhouse studies were conducted from 1996 to 1998 to determine the efficacy of spinosad, and acephate, against western flower thrips (Frankliniella occidentalis Pergande) on transvaal daisy (Gerbera jamesonii H. Bolus ex. Hook f). In addition, the number of natural enemies inside and outside the greenhouse was determined. Studies were arranged in a randomized complete-block design with four b...

toxicity of spinosad was primarily evaluated with three bioassay methods: feeding, spraying (residual exposure) and combination with larval medium against one susceptible and one field population. feeding method was selected as efficient method for survey of susceptibility or resistance of seven field populations. in feeding bioassay method, spinosad ld50 of susceptible strain at 24h and 72h we...

insect growth regulators and spinosyns which are physiologically and ecologically selective, respectively, have been investigated as replacements or complements to non-selective conventional insecticides. the effects of diflubenzuron, hexaflumuron, profenofos, spinosad and thiodicarb were assessed on the 1st instars of cotton bollworm, helicoverpa armigera (hã¼bner) using dietary and leaf disc ...

Irrational applications of insecticides on vegetable crops are very common in Bangladesh, resulting harmful consequences for the environment and human health. Therefore, a study was conducted to evaluate efficacy biological botanical okra shoot fruit borer grown open fields. Four were used this study, namely Bacillus thuringiensis (Bt), Spinosad 45 SC, Abamectin 1.8 EC, Azadirachtin 1% EC an un...

Abstract Background Cultivation of citrus (Sapindales: Rutaceae) crops is continuously expanding in Egypt given the favorable ingredients citriculture. Notwithstanding Egyptian rank as world's largest orange exporter, Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), one major pests that considerably reduces quality crops. Contrary to hazardous organophosp...

Considering the economic significance of S. dorsalis in chilli crop, a study was carried out at ICAR-Research Complex for Eastern Region, Farming System Research Centre Hill and Plateau Ranchi, Jharkhand during spring season 2019 2020 to find effective chemical molecules managing this pest. Effectiveness 8 modern insecticides against their effect on coccinellid predators evaluated. Efficacy det...

Management of onion maggot, Delia antiqua (Meigen), in onion requires the use of an insecticide applied at planting. Insecticide resistance and a dearth of available products have stimulated an effort to identify new insecticides for onion maggot control, especially chemistries that can be delivered as seed treatments. Onion seeds film-coated with fipronil, spinosad, clothianidin or thiamethoxa...

Under laboratory conditions, the comparative effects of two insect growth regulators, chlorfluazuron and oxymatrine, and spinosad as a biopesticide were examined on honey bee workers (Apis mellifera L.). Separate groups of bees were left for 24 h to feed on 50% sucrose solution containing different concentrations of the tested insecticides, and the lethal concentration that caused 50% mortality...

The influence of post-treatment temperature on the toxicities of two pyrethroids (lambda-cyhalothrin and bifenthrin), a carbamate (methomyl) and a spinosyn (spinosad) to Ostrinia nubilalis (Hubner) larvae was evaluated in laboratory assays. From 24 to 35 degrees C, the toxicities of the pyrethroids decreased 9.5- and 13.6-fold while spinosad toxicity decreased 3.8-fold. The toxicity of methomyl...

abstract in a laboratory study the effect of three insecticides (pirimicarb, pymetrozine and spinosad) was evaluated on aphelinus mali a parasitoid of woolly apple aphid. to investigate the contact effect, adults were caged for 16 hours in petri-dishes containing apple leaves sprayed with each insecticide. to determine the oral toxicity in the same period of time, other petri-dishes containing ...
