Abstract Many plant-dwelling mites reside on lower leaf surfaces. The biological impact of solar ultraviolet-B (UV-B) radiation spider has been demonstrated over the last decade. Due to serious problem acaricide resistance in mites, development alternative control methods and establishment an integrated pest management (IPM) strategy are urgently needed, especially for greenhouse horticultural ...

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is an economically important pest of ornamental plant in Iran. The population abundance and spatial distribution were studied on five Rosa cultivars including Maroussia, Wendela, Elderado, Wenedetta, and Hot Lady during two growing seasons of 2011 and 2012 in greenhouse. The k parameter, index of dispersion, Lloyd’s m...

Spider mites, a cosmopolitan pest of agricultural and landscape plants, thrive under hot and dry conditions, which could become more frequent and extreme due to climate change. Recent work has shown that neonicotinoids, a widely used class of systemic insecticides that have come under scrutiny for non-target effects, can elevate spider mite populations. Both water-stress and neonicotinoids inde...

Tetranychus urticae is one of the most important pests of strawberry cultures in Morocco. Current control of this pest relies almost exclusively on acaricides. Unfortunately, this mite has developed resistance to most of the available acaricides. Moreover, insecticide treatments are responsible for the reduction or suppression of beneficial species such as natural predators. Thus, identificatio...

ABSTRACT Silicon is an inducer of plant resistance to arthropod pests, being a promising strategy for integrated management. The aim this study was evaluate the effect silicon on biological, reproductive and population aspects parental F1 generations two-spotted spider mite strawberry plants. Potassium silicate, nanosilica water were applied Two-spotted females confined leaf disks oviposition a...

lations sometimes develop. Such variations are apparently the result of predators and parasites, climatic differences, varying tree conditions such as tree vigor and the plant growth cycle, all o€ which affect the feeding mites. The effects of temperature and humidity were the only considerations in the study reported here. Climatological conditions were found to vary from grove to grove and fr...
