Nonthermal air plasma, which can be generated by discharge, contains large amounts of reactive oxygen species (ROS), nitrogen (RNS) and high-energy particles. The ROS RNS have strong oxidizing properties, the particles break chemical bonds in organic compounds, a process used to degrade matter such as pesticides. In present study, effects nonthermal plasma on degradation several pesticides were...

In the laboratory, an acaricide-susceptible strain of citrus red mite, Panonychus citri (McGregor) (LS-FJ), was used to screen for resistance spirotetramat. A spirotetramat-resistant (ST-NK) obtained after continuous selections through 15 selection cycles (45 generations) exhibited 1668.4-fold greater when compared parent generation. Instability spirotetramat in mites observed during 11 months ...

The use of synthetic acaricides for management of pest mites may alter the efficacy of the ectoparasitoid Tamarixia radiata (Waterston) in biological control of Diaphorina citri Kuwayama, the vector of the bacteria associated with huanglongbing (HLB) in citrus orchards. We evaluated the toxicity of 16 acaricides that are recommended for the control of citrus-pest mites to T. radiata. Acrinathri...

demographic toxicology is a common method for an investigation of the sub lethal effects of pesticides on natural enemies. the present study was conducted to evaluate the side effects of the extracts of calotropis procera (willd.) r. br. (asclepiadaceae), teucrium polium l. (labiatae), fumaria parviflora lam. (fumariaceae) and thymus vulgaris l. (labiatae) in comparison with three pesticides: h...

the side effects of three pesticides, hexaflumuron, pymetrozin and spirodiclofen and four plant extractions including, calotropis procera (willd.) r. br. (asclepiadaceae), teucrium polium (labiatae), fumaria parviflora lam. (fumariaceae) and thymus vulgaris l. (labiatae) were evaluated on survival rate and reproductive parameters of chrysoperla carnea (stephens) at 26±1oc, 60±5% rh and 16:8 (l:...

common pistachio psylla, agonoscena pistaciae burckardt and lauterer (hemiptera: aphalaridae) is one of the economical pest among the pistachio orchards. the adonis' ladybird, hippodamia variegata (goeze) (col: coccinellidae) is one of the most prominent coccinellid predator in pistachio orchards. it is omnivorous and feed on aphids and psylla. functional response studies using a suitable ...

Citrus leprosis mite is an important pest to Brazilian citriculture. Due the potential damage caused by virus transmitted this mite, synthetic acaricides are main management strategy used citrus growers reduce vector population. The current review aims provide historical data on use of control and factors involved with efficacy these products. To get know products that were have been we scienti...
