Abstract/ Executive Summary:

The attack of the insect started when the bee trees had new leaves after summer. The population was high in September and October when flowering initiated. The population abundance declined from November to December. Indian ber plants seemed to be more suscepible than wild ber to this pest. Spraying of diazinon and zithiol on the ber trees killed immature of P. citrella almost at the same rate and 0.05% AI of these insecticides might be effective for the control of this pest.

Keywords: Population Abundance, Leaf miner,Control Ber

Location: Bangladesh Agricultural University, Mymensingh

Start Date: 00-09-1984

End Date: 00-12-1984

Program Area: Pest Management

Commodity: Fruit

Objectives:

To study the abundance of Leaf Miner and its control on the ber.

Methodology:

Studies were made during the period from September to December, 1984. The population census of Phyllocnistis citrella was done on six selected ber trees in the campus and garden of Bangladesh Agricultural University, Mymensingh. Ten small branches (twigs) of each tree were chosen randomly for sampling at weekly intervals. Five infested leaves from each branch (twigs) were randomly chosen and the numbers of insect were counted per leaf per free on the basis of number of mines per leaf. To determine the extent of damage, total number of damaged and fresh leaves were counted per twig per tree on 10 twig basis from the same selected trees. To test the effectiveness of insecticides, a field trial was conducted with diazinon 60 EC and zithiol 57 EC at 2 doses viz, 0.075 and 0.05 % Al. Four infested ber trees of medium size were sprayed with the insecticides with one tree sprayed with water.
