Morphological characters and distribution of mites in strobery plant ( Fragaria Vesca L.) in high land Sembalun

Abstract

Pest mites are reported to attack strawberries in vegetative to generative stages. But not much information is available regarding the types of pest mites and predators associated with strawberries in the Sembalun area This study aims to determine the morphological character and distribution of pest mite species on strawberry plants in the Sembalun area. This research has been carried out from November 2017 to February 2018 in two central strawberry production villages namely Sembalun Bumbung and Sembalun Lawang, Sembalun District, East Lombok Regency, West Nusa Tenggara Province. The method used in this research is descriptive method with survey techniques and data collection in the field. Two species of pest mites were found, namely Brevipalpus phoenicis Geijskes and Tetranychus kanzawai Kishida with an average population of 0.9 ± 2.9 mites / plants. The dominance index and the highest abundance are Tetranychus kanzawai valued at 0.875 and 93.55%. Pest mite population distribution is quite even, where both mite species are found at each sampling location.
