Abstract/ Executive Summary:

A research work on the pollinator of litchi was conducted at Fruit Research Station, Binodpur, Rajshahi during February-April, 2014 to know about the pollinator visited the litchi orchard during flowering stage. The survey of insect species visiting litchi flowers indicated that the highest number of species were noted from the order Diptera (flies), 4, then Hymenoptera (ants, bees, wasp), 1. In BARI litchi-1 the insect population (number/panicle) was recorded the highest 0.98 of Syrphid fly in decreasing order of population were flower fly (0.22), Honey bee (0.10), House fly (0.03) and Blow fly (.02). In Bombai litchi the pollinator was noticed the highest 1.55 of Syrphid fly in decreasing order of Honey fee (1.05), Flower fly (0.81), Blow fly (0.60) and House fly (0.05). In Dinajpuri litchi, the pollinator was recorded the highest 3.38 of Blow fly in decreasing order of Flower fly (0.32), Honey bee (0.08), Syrphid fly (0.05) and House fly (0.04). The highest number of insect was observed as pollinators/visitor at the first half of the day.

Keywords: Litchi, Pollinators, Flowering stage

Location: Fruit Research Station, BARI, Binodpur, Rajshahi

Start Date: 00-02-2014

End Date: 00-04-2014

Program Area: Pest Management

Commodity: Litchi

Objectives:

To know about the pollinators visited the litchi orchard during flowering stage.

Methodology:

The field experiment was conducted at the Fruit Research Station, BARI, Binodpur, Rajshahi during Feruary-April 2014. Forty years of litchi trees were selected to record data. Three varieties of litchi viz BARI litchi-1, Bombai and Dinajpuri were observed and number of different insects were counted as pollinators/visitors. BARI Litchi-1 and Bombai observed up to10 days continuously from 12 to 21 March and 22 to 31, respectively. March but Dinagpuri observed only 4 days 1 to 4 April. Total 15 panicles were tagged for each variety and data were recorded at one hour interval from 6 am to 6 pm and averaged.
