Abstract The efficiency of Jasmonic acid concentrations 0, 5, 50 and 100μM was examined mortality adult female nymphs the two-spotted spider mite Tetranychus urticae fed on leaves over four time intervals 12, 24, 36 48 hours. results showed significant effect treatments corrected ratios for both stages, as well interaction variety, concentration time. In general, indicated increase with period....

Understanding the impact of a pest species on a particular crop is critical for the success of a pest management program. Field studies were conducted to determine the effect of the twospotted spider mite, Tetranychus urticae Koch, on marketable yield of strawberries during the 2008/2009 and 2009/2010 growing seasons. Low, medium, and high mite infestation levels were established by initial ino...

The main insect pests vary in different geographical areas. Studies have shown that the pomegranate biocenosis is dominated by such as Euzophera punicaella Mooze, Aphis punicae Theob, Pseudococcus komstoci Kuw, common spider (Tetranychus urticae Koch) damage was detected. Pomegranate juice gives 10-12 generations of pomegranates a year. These mainly orchards Tashkent region.

Biological efficacy of rapeseed spray oil against twospotted spider mite (Tetranychus urticae Koch) on cucumber, against European red mite [Panonychus ulmi (Koch)] on apple, green peach aphid (Myzus persicae Sulzer) on pepper and pear psylla [Cacopsylla pyri (L.)] was evaluated in seven field and three greenhouse trials at eight localities in Serbia during 2005-2008. The efficacy of rapeseed sp...

Phytoseiulus persimilis Athias-Henriot is an important biocontrol agent for controlling spider mites (Tetranychus spp). Rearing P. relatively expensive due to the need raise (e.g. Tetranychus urticae Koch), as prey, on live plants. Frozen eggs of T. can be easily stored and used a potential feed laboratory rearing persimilis. This study investigated performance frozen compared with fresh food U...

The carmine spider mite (CSM), Tetranychus cinnabarinus, is an important pest mite in agriculture, because it can develop insecticide resistance easily. To gain valuable gene information and molecular basis for the future insecticide resistance study of CSM, the first transcriptome analysis of CSM was conducted. A total of 45,016 contigs and 25,519 unigenes were generated from the de novo trans...

The impact of daily temperature variations on arthropod life history remains woefully understudied compared to the large body of research that has been carried out on the effects of constant temperatures. However, diurnal varying temperature regimes more commonly represent the environment in which most organisms thrive. Such varying temperature regimes have been demonstrated to substantially af...

BACKGROUND The solanaceous fruit crop pepino (Solanum muricatum Ait.), originating in the Andes, is grown commercially in South American countries and New Zealand. In these areas, pests and diseases of pepino have been identified well; however, to date, these have seldom been investigated in detail in Japan. Herein, we attempt to reconstruct an agricultural production system for commercial pepi...

Surface arthropods on pome fruits can cause export problems and disrupt commercial markets. Eliminating insects and mites on the packing line would be the last opportunity to provide for pest-free produce. In this study, an experimental packing line was used to evaluate techniques using different surfactant baths, pressurized water sprays, and styles of rotating brushes to remove field-collecte...
