Greenhouse whitefly, Trialeurodes vaporariorum is a major pest of horticultural and ornamental plants usually controlled with insecticides or biological control agents. In the current study, we examined effects synthesized zinc oxide nanoparticles (ZnO NPs) Beauveria bassiana TS11 on T. adults. ZnO NPs were by precipitation method. Field emission scanning electron microscope images indicated that non-compacted uniformly. X-ray diffraction results confirmed hexagonal wurtzite structure NPs....

Toxicity Allium sativum and Eucalyptus globulus essential oils were investigated against Ephestia kuehniella larvae in addition to physiological effects on digestive enzymes, intermediary metabolism, antioxidant response storage macromolecules. The LC50s of 2.801 6.111 µl/ml recorded for A. sativum- E. EOs as the highest concentrations caused 83.3% 80% larval mortality. lowest activities α-amylase, TAG-lipase, carboxypeptidase treated by EO, while EO showed trypsin, chymotrypsin,...

Ephestia kuehniella Zeller is a key pest by severe deficiencies on quantity and quality of stored products. Due to concerns made synthetic insecticides, use natural products (like botanical insecticides) great importance as an alternative management. In the current study, effect diallyl disulfide was determined digestive enzymes those involved in intermediary metabolism E. kuehniella. Concentration 0.31% obtained LC50 followed bioassay experiments. Activities α-amylase, proteases, alanine...

Greater knowledge of the changes in expression and transcription patterns hsps related proteins could provide greater insight a better understanding honey bee responses to stress at cellular physiological levels.A sudden large decline honeybee population (disappearing disease), which is called colony collapse disorder (CCD), has been attributed pathogen infections or pesticide toxicity (Oldroyd, 2007).The mechanism CCD still unknown.Pesticides, pathogens (viruses mites), environmental...

SummaryHoney bees are beneficial insects that might be harmed by pesticides and application of repellent chemical compounds has been considered to one the best ways protect them. This study shows effects 2-ethylhexylamine, dibutylamine methyl salicylate on honey as chemicals, with without benzyl benzoate, dibutyl phthalate alcohol fixative compounds. The was conducted canola alfalfa fields in spring summer. design experiment factorial split form randomized blocks. Sampling carried out twice...

Knowledge on the population of genetic structure and ecological behaviour Apis dorsata from Peninsular Malaysia is needed for effective management conservation this species since unsustainable whole solitary low nest cutting product harvesting current common practice here. The analysis 15 single locus DNA microsatellite markers samples 20 nests A. showed that while these were polymorphic, high intracolonial relatedness existed. Furthermore, in general, slightly negative values intercolony...

Purpose: Bactrocera zonata (Diptera, Tephritidae), is considered as a dangerous pest of mango in the south Iran, which its control one main concerns farmers who are facing numerous problems.To assay different methods for controlling B. zonata, this study was carried out.Method: The treatments were, A) spraying 7% methyl eugenol+7% technical malathion on trunk and tree branches, B) soaking 8-10 layers jute sacks with previous treatment that were attached to C) bucket trap along chipboard...

SummaryApis dorsata is a major pollinator in the rainforests of Peninsular Malaysia, which threatened by frequent harvesting via removal whole comb nests from trees during season. There an urgent need for conservation this species and long-term survival tropical lowland forests. In paper, genetic relatedness A. aggregations are addressed with preliminary study on local populations Malaysia. The analysis 30 single locus DNA microsatellite markers three at intra-aggregation level showed that...

Botanical based-insecticides are presently recognized to interfere behavioral and physiological performances of herbivorous insects. In the current study, insecticidal properties Pimpinella anisum, Foeniculum vulgare Heracleum persicum essential oils (EOs), their main component, trans-anethole, were studied on a destructive pest mulberry leaves, Glyphodes pyloalis Walker. The effect (EOs) larval feeding was evaluated by leaf-dipping method demonstrated highest antifeedant activities F. H....

The Adonis ladybird, Hippodamia variegataGoeze (Coleoptera: Coccinellidae) is known as an important predator of the Common pistachio psylla, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae). Despite using selective pesticides to manage pests in orchards, these chemicals have influenced non-target organisms like predators and parasitoids. In present study, effects spirotetramat imidacloprid (500 400 ml/1000 L, respectively) on some biological parameters H. variegata fed...

This study investigated the effect of Teucrium polium L. essential oil (Tp EO) and α-pinene as its major component on detoxifying- intermediary-engaged enzymes Ephestia kuehniella Zeller. Fourth instar larvae were separately fed treated artificial diets incorporated with LC50 concentration Tp EO (4.91 μl ml-1) (10.66 ml-1). After three time intervals (24, 48, 72 hours), larval hemolymph was extracted to determine enzymatic activities. Activity esterase, alanine aspartate aminotransferases,...

Honey bees may experience the adverse effects of environmental contaminants when exposed during foraging trips, or something to that effect. We hypothesized octopamine (OA), with important functions in reward signaling and learning, can improve behavior honey under chemical stress. Memory retention sucrose responsiveness were evaluated using proboscis extension reflex (PER) assay. The one-day-old separately diazinon, imidacloprid, paraquat, manganese, thymol at concentrations 0.22, 29.04,...

AbstractAcrosternum millierei (Hemiptera: Pentatomidae) is a major pest of pistachio because it attacks nuts from early spring to the time harvest. In this research, physiological adaptations non-diapausing and overwintering adults, including changes in supercooling point (SCP), survival at low temperatures, accumulation polyols were studied. The results showed that SCP decreased significantly mean value −11.8 °C July 2018 (non-diapause adult) −17.6 February (overwintering adult). Survival...

Crocus sativus L. (Iridaceae) known as saffron is the most commercially important medicinal food product in Iran and worldwide because of its significance for exporting commercial. However, health this plant adversely threatened by abiotic biotic stress. Bulb mite Rhizoglyphus robini Claparede (Acari: Acaridae) stress oligophagous main pest tuber plants, commonly found all cultivated producing areas could decrease economic value. The mites tunnel through corms allowing entry fungal bacterial...

Gaeolaelaps aculeifer (Canestrini) (Acari: Laelapidae) is an edaphic predator of several agricultural pests. Development simple and low-cost innovative mass rearing techniques the use this to control soil pests have high importance. For production G. aculeifer, three growth environments were evaluated. Saffron corms layered potatoes used feed mites, mixture "cocopeat + perlite saffron chaff" was maintain more moisture prepare environment for ventilation porosity, increase hiding places,...

This paper reports on a new species of mites the genus Laelaspis from Iran – latisetus sp. nov. was collected clinging to Pheidole pallidula (Nylander) (Hymenoptera, Formicidae) southeast Iran. The is described and illustrations provided based morphological characters adult female.
