Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...

The common pistachio psylla, Agonoscena pistaciae Burckhardt and Lauterer (Hemiptera: Psyllidae), is a key pest in pistachio orchards in Iran. Chemical control is a common method to manage this pest. Compatibility between natural enemies and pesticides is a primary concern in programs of integrated pest management of the psyllid pest. In this research, susceptibility of fifth instar nymphs of A...

Two strains of the common bed bug, Cimex lectularius L., eggs and first instars collected from pyrethroid-resistant adults were evaluated for insecticide resistance and compared to a susceptible strain. Dose-response bioassays were conducted using two insecticide formulations (Temprid: imidacloprid/β-cyfluthrin, and Transport: acetamiprid/ bifenthrin). The lethal concentration (LC50) for the tw...

Coccinella septempunctata is a nontarget beneficial arthropod and an important aphid predator in agricultural crops. In this study, the toxic effects of neonicotinoid acetamiprid on C. were investigated to determine its applicability efficacy against predator. The results toxicity test showed that second instar larvae most sensitive acetamiprid. LC50 values 1st, 2nd, 3rd, 4th 15.767, 9.412, 18....

cotton aphid, aphis frangulae gossypii glover, is a major pest of cucumber in iran. one of the important parasitoids playing role in population control of this pest in the fields and greenhouses is lysiphlebus fabarum marshall. in this study, we investigated sensitivity of different instars of cotton aphids and pupal stage of l. fabarum to field recommended and half-recommended concentration of...

Pesticides are usually used as an effective tool to control pests in agriculture; however, these chemicals may be a threat nontarget organisms, especially aquatic because environments the last station of pollutants. The present study evaluated toxicity commercial formulation neonicotinoid (acetamiprid 20% SP) systematic pesticide on survival, hematology, and histology grass carp (Ctenopharyngod...

Laboratory studies were carried out to compare the toxicity of seven foliar insecticides to four species of adult beneficial insects representing two families of Hymenoptera: Aphelinidae (Aphytis melinus Debach, Eretmocerus eremicus Rose & Zolnerowich, and Encarsiaformosa Gahan) and Mymaridae (Gonatocerus ashmeadi Girault) that attack California red scale, Aonidiella aurantii (Maskell); sweetpo...

Honey bees (Apis mellifera) are one of the most important pollinating species flowering plants. Recently, populations honey have been declining due to a combination factors, including widespread use agricultural pesticides. Laboratory studies were conducted determine acute oral toxicity different formulated pesticides bee adults. In particular, we assessed two neonicotinoids (acetamiprid, Assai...
