Abamectin has been widely used as an insecticide/acaricide for more than 30 years because of its superior bioactivity. Recently, an interesting phenomenon was identified in the carmine spider mite, Tetranychus cinnabarinus, an important pest in agriculture. The gamma aminobutyric acid (GABA) contents in a laboratory abamectin resistant strain of T. cinnabarinus (AbR) were significantly increase...

We tested the effects of high humidity and submergence on egg hatching of spider mites. In both the high humidity and submergence treatments, many Tetranychus and Panonychus eggs did not hatch until after the hatching peak of the lower humidity or unsubmerged controls. However, after humidity decreased or water was drained, many eggs hatched within 1-3 h. This was observed regardless of when hi...

This article is devoted to the research on use of lime-sulfur decoction and surface-active substance (surfactant) against dangerous spider mites found in cotton plants. It was that cited preparations Bukhara-6 type plant moderation resulted extra harvest amount 4.2 - 4.4 centner per hectare.

We studied developmental plasticity under food stress in three female-biased size dimorphic predatory mite species, Phytoseiulus persimilis, Neoseiulus californicus, and Amblyseius andersoni. All three species prey on two-spotted spider mites but differ in the degree of adaptation to this prey. Phytoseiulus persimilis is a specialized spider mite predator, N. californicus is a generalist with a...

The first checklist of spider mites (Tetranychidae) Transcarpathia, Ukraine is compiled based on the revision collection materials stored in I. Schmalhausen Institute Zoology National Academy Sciences Ukraine. mite collections Akimov, A. Putrashik, and authors were studied, thus covering a 45 year-long period research study region. includes 28 species 10 genera tetranychid mites, which about 40...

BACKGROUND Chemical suppression of arthropod herbivores is the most common approach to plant protection. Insecticides, however, can cause unintended, adverse consequences for non-target organisms. Previous studies focused on the effects of pesticides on target and non-target pests, predatory arthropods, and concomitant ecological disruptions. Little research, however, has focused on the direct ...

This article provides information on the sulfur-containing LSD (decoction of sulfuric lime) and externally active substance (EAS) used against cotton spider mites. It has been established that when using these preparations, Bukhara-6 variety received an additional yield 4.2-4.4 c/ha with good commercial indicators.
