Jatropha curcas L., once considered as a border or fence plant in India, has recently attained a new economic dimension as a biofuel crop. Though this crop suffers less damage from pests and diseases, some do cause a certain amount of injury. Phytophagous mites, namely broad mite, Polyphagotarsonemus latus (Banks), and red spider mite, Tetranychus urticae Koch, infest Jatropha curcas. Experiments were conducted during the year 20052006 to study the population dynamics and biology of these mites. The populations of broad mite and of the red spider mite were highest during November and October, respectively. The total life cycle of broad mites lasted six days; females and males lived for nine and seven days, respectively, whereas that of the spider mite was six days. Among several chemicals assayed, abamectin 0.0009% provided best control of both pests.
