abstract
Central Tasar Research & Training Institute, Ranchi has been conducting survey on regular intervals for assessment of any new pest emergence or loss of any pest due to climate change and extreme weather conditions or any other reason in Jharkhand, which contributed more than 80% tasar cocoon production in India. In the year 2018, infestation of jumping plant lice, Phylloplecta hirsuta. [syn. Megatrioza hirsuta (Crawford) (Trioza hirsuta)] was observed in primary tasar food plants Terminalia arjuna (Arjun) and T. tomentosa (Asan) at CTR&TI, Ranchi research farm and Pilot Project Centre, Kharswan, Singhbhum region of Jharkhand. The insect belongs to order Hemiptera, superfamily Psylloidea and family Triozidae. Symptom of pest on tasar food plants was noticed on the terminal leaves in the form of complete curling of the leaves. The nymphs having white waxy skin feed on the dorsal side of the leaves and fold them outside in. Adults of the pest have a light shining yellowish body with white transparent wings that extend well beyond pointed abdomen. Members of the family Triozidae are commonly called jumping plant lice and form galls on plants by their feeding action. Basic information about this insect will be helpful for easy identification of pest symptom and preparation of IPM package for the management of pest in tasar food plants in a changing environment.
