Abstract The control of the Mediterranean fruit fly (Medfly), Ceratitis capitata , in citrus orchards Spain is mainly based three insecticides (spinosad, lambda-cyhalothrin and deltamethrin) liberation sterile males. However, Medfly compromised by development resistance detection spinosad-resistant alleles field populations. We report here, for first time, to deltamethrin populations collected ...

In regions with a humid summer climate, the use of water-soluble bait to control apple maggot is often limited by rainfall. We studied increasing the rainfastness of GF-120 fruit fly bait by adding paraffin wax emulsion. First, we verified that adding 10% wax to a mixture containing 16.7% GF-120 did not reduce the mortality of female apple maggot compared with GF-120 without wax. In addition, w...

entomopathogenic fungi may be affected by pesticides used to protect crop plants. the in vitro compatibility of beauveria bassiana and metarhizium anisopliae with three fungicides and 16 insecticides was evaluated. the formulations of pesticides were tested in three concentrations (mean concentration (mc), half mc and twice the mc). all tested fungicides, at three concentrations, were incompati...

Abstract Background Spodoptera littoralis Boisad. (Lepidoptera: Noctuidae) is an important pest causing significant losses to agricultural crops worldwide. Management practices for this insect rely on insecticides applications throughout the entire season over wide ranging temperature. However, studies involving development of resistance in S. against these at different temperatures are limited...

colorado potato beetle, leptinotarsa decemlineata is one of the major insect pests of potato. toxicity of spinosad, as a bio-rational insecticide, was investigated against various developmental stages of this pest. bioassays were conducted by using the eggs, neonates, first, second, third and fourth instar larvae and adults. the potato leaves were impregnated with different concentrations of sp...

BACKGROUND Insecticide resistance in the housefly, Musca domestica, has been investigated for more than 60 years. It will enter a new era after the recent publication of the housefly genome and the development of multiple next generation sequencing technologies. The genetic background of the xenobiotic response can now be investigated in greater detail. Here, we investigate the 454-pyrosequenci...

Fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) is an important pest of maize (Zea mays L.) crops in Brazil. The effects of beta-cypermethrin, chlorfenapyr, chlorpyrifos, spinosad, etofenprox, triflumuron, alpha-cypermethrin/teflubenzuron, and lambda-cyhalothrin/thiamethoxam on Trichogramma pretiosum Riley, 1879 (Hymenoptera: Trichogrammatidae) immature stages we...
