Abstract/ Executive Summary:

The investigation was carried out at the ber orchards of Lac Research Station (LRS), Chapai Nawabgonj; Nachole, Chapai Nawabgonj; Nobogonga, Rajshahi; Pirgonj, Rangpur and Nilphamari sadar during November 2010 to May 2011 in baishakhi lac crop and July to October 2011 in kartiki lac crop seasons with a view to document the incidence and severity of predators of lac insect. Results indicated that the rate of infestation of Eublemma amabilis was higher than Pseudohypatopa pulverea in all study locations. In Baishakhi crop, the highest population (per 10 cm twig/ plant ) of both the predators, E. amabilis (2.78) and P. pulverea (1.68) was recorded from LRS, Chapai Nawabganj . But in kartiki crop, the highest population (per 10 cm twig/ plant ) of E. amabilis (3.37) was recorded from LRS, Chapai Nawabganj while P. pulverea (1.94) from Nachole ,Chapai Nwabganj.

Keywords: Lac, Eublemma amabilis, Pseudohypatopa pulverea

Location: Lac research station,Chapainawabganj

End Date: 15-10-2011

Program Area: Pest Management

Objectives:

To know the incidence and severity of predators of Lac insect in different locations of Bangladesh.

Methodology:

The investigation was carried out at the ber orchard of LRS, Chapai Nawabgonj; Nachole, Chapai Nawabgonj; Nobogonga, Rajshahi; Pirgonj, Rangpur and Nilphamari sadar during November 2010 to May 2011 in baishakhi and July to October 2011 in kartiki lac crop seasons with a view to know the incidence and severity of predators of Lac insect. The experiment was laid out in RCB design with 5 treatments (locations) and 3 replications. One Ber plant about 20 years old was considered as one replication of a treatment. Each sample was 10 cm length and 5 samples were taken from each plant for data collection in-sito. The number of predator’s larvae was recorded separately for each treatment.
