Abstract

Lampung Province is one of cassava producers in Indonesia. Many cassava clones are cultivated in this area, contributing to more than thirty percent of total national cassava production. Cassava is also an important cash crop in Lampung. However, the infestation of pests and diseases can limit cassava production in the field. These infestations may vary from clone to clone. The objectiveof this research was to document the infestation level of major plant pests including mealybugs, red mite, and leaf spot disease on various clones from some locations of cassava fields in Lampung. A survey was conducted on August 2016 in cassava fields belongd to farmers in several locations in East Lampung (NTF, Margatiga), Bandar Lampung (Sukarame), and South Lampung (ITERA) as well as field experimental plots belong to Faculty of Agriculture, University of Lampung at Natar. The results showed that cassava mealybug (Phenacoccus manihoti), papaya mealybug (Paracoccus marginatusi) and red mite (Tetranychus urticae) have infested almost all cassava clones in surveyed locations. The prevalence of red mite infestation tended to be higher than that of mealybugs. Cassava diseases found were brown leaf spot and virus mosaic. Brown leaf spot infested cassava clones in mild to moderate severity found on all cassava clones and locations, while viral disease with prevalence of 78% was only found on Duwet 1 clone in field experimental plot
