Use of Food Traps for Monitoring Termite Population in Tea

Mainuddin Ahmed
Director, Bangladesh Tea Research Institute, Srimangal, Moulvibazar

Abstract/ Executive Summary:

An experiment was conducted to monitor termite population in tea area. The experiment was laid out with a randomized completely block design (RCBD) at Bangladesh Tea Research Institute main farm. Five types of food traps, namely, 1) Saw dust @ 100g, 2) Tissue paper @ 100 cm long, 3) Dried tender bamboo sleeves @ 100 sleeves, 4) Jute sticks @ 100 sticks and 5) Susceptible soft timber @ 100 pieces were used as treatments in this experiment. In the control plots, nothing was used. Each treatment was replicated thrice. The intensity of termite damage was recorded at 30 days interval during the study. Results revealed that the proneness of invasion of termite to different food traps differed significantly from each other. The damage matrix indicates that the dried tender bamboo sleeves (73.50%) are more susceptible to termite damage than that of soft timber (67.50%) and jute sticks (56.75%). On the other hand, saw dust (27.50%) and tissue paper (28.00%) are less damaged or damaged by termite activity. So, food traps like bamboo sleeves and soft timber are considered to be a suitable tool for destruction and management of termite.

Program Area: Pest Management

Commodity: Insects, Tea

Objectives:

Little research has been done on food trap for the management of termite in tea. In order to monitor termite population and determine the damage matrix on those variable food materials in plantation areas or in rehabilitation areas and subsequently to control the invading termites, simple field testing devices using food traps were constructed at Bangladesh Tea Research Institute main farm for the following purposes: i. Detection survey: To determine if species are present in an area. ii. Delimiting survey: To determine the boundaries of an area considered to be infested or free from termite pest. iii. Monitoring survey: To verify the characteristics of a pest population including seasonal population fluctuation, relative abundance, host sequence and others.

Methodology:

An experiment was conducted to monitor termite population in tea area at BTRI main farm. Five types of food traps, such as, 1) Saw dust, 2) Tissue paper, 3) Dried tender bamboo sleeves, 4) Jute sticks and 5) Susceptible soft timber were used as food traps in this experiment. Untreated control treatment was also included.

A randomized complete block design (RCBD) was followed with the following six treatments:

T1: Saw dust; T2: Tissue Paper; T3: Dried tender bamboo sleeves; T4: Jute sticks, T5: Susceptible soft timber and T6: Control

Each treatment was replicated thrice. Saw dust @ 100g/replication was put in lump on the bare soil. Similarly tissue paper @ 100 cm long/replication was spreaded. On the other hand, dried tender bamboo sleeves (each 50 cm long) @ 100 sleeves/replication, jute sticks (each 50 cm long) @ 100 sticks/replication and susceptible soft timber (50 cm long) @ 100 pieces/replication were scatteredly placed over the soil surface. In the control plots, nothing was used. The intensity of termite damage was recorded at 30 days interval during the study.

Achievement/Findings:

It was observed in the practical field that the use of food traps especially bamboo sleeves and or soft timber induce termite infestation in derelict redundant tea sections and subsequent use of proper pesticide to control them might provide an environmentally sustainable control method for termite. So, food traps like bamboo sleeves and soft timber are considered to be a suitable tool for destruction and management of termite.
