Abstract/ Executive Summary:

To evaluate the effectiveness of some non-chemical and chemical components of IPM against the red pumpkin beetle (RPB) on sweet gourd, a field trial was conducted. Results revealed that mosquito net barrier was the effective non-chemical treatment to protect sweet gourd from RPB infestation, followed by use of muskmelon as trap crop and hand picking of RPB adults. The most effective insecticide was Nitro 505 EC @ 1 ml/L twice at 7 days interval, followed by Foratap 4G @ 4 g/plant twice at 10 days interval in reducing the number of RPB as compared to other treatments. In terms of reduction of leaf infestation over control, use of mosquito net barrier provided the highest reduction in leaf infestation (>80%) over the untreated control followed by Nitro 505 EC @ 1 ml/L of water twice at 7 days interval, Foratap 4G applied @ 4 g/plant twice at 10 days interval and planting of musk melon as trap crop. Considering all stages of plant growth, the lowest percentage of leaf infestation was observed in plots treated with use of mosquito net barrier as mechanical control, followed by plots treated with planting of musk melon as trap crop and plots treated with Nitro 505 EC @ 1 ml/L of water twice at 7 days interval.

Location: Experimental Field of Entomology, BSMRAU

Start Date: 01-03-2008

End Date: 30-06-2008

Program Area: Pest Management

Commodity: IPM

Objectives:

The present experiment was conducted to evaluate the effectiveness of some non-chemical and chemical components of IPM against the red pumpkin beetle and also to identify the appropriate and effective non-chemical approaches and one or two suitable insecticide(s) as components of IPM package(s) with optimum dose and frequency of application.

Methodology:

A field experiment was conducted in the farm of BSMRAU, Gazipur during March to June, 2008 to evaluate the effectiveness of some non-chemical and chemical components of IPM against the red pumpkin beetle (RPB). A year round local variety of sweet gourd was used in the experiment. Nine management tactics of non-chemical and chemical components were tested with an untreated control. Management tactics were: T₁ = Planting of musk melon as trap crop, T₂ = Hand picking of adult RPB, T₃ = Use of mosquito net barrier for 4 weeks, T₄ = Foratap 4 G @ 4 g/ plant , T₅ = Foratap 4 G @ 3 g /plant, T₆ = Emithion 50 EC @ 2 ml / L of water, T₇ = Morter 48 EC @ 1 ml / L of water, T₈ = Vitabryl 85 WP @ 34.4 g / L of water, T₉ = Nitro 505 EC @ 1 ml / L of water and T₁₀ = Untreated control (only water spray). The experiment was laid out in RCB design with three replications. Data on number of beetles per leaf per day, per cent leaf infestation per plant, per cent leaf area damage per infested leaf at 7, 14, 21, 28 and 35 days after application (DAA) and per cent leaf infestation at seedling, vegetative and reproductive stages of plant growth were recorded. All the data were analyzed through ANOVA using MSTAT-C software. The percentage data were transformed through Square root or Arc Sin transformation method as and when needed. DMRT was used to compare the treatment means.

Achievement/Findings:

The findings revealed that mosquito net barrier (T₃) is the effective non-chemical means to protect sweet gourd from RPB infestation, which was followed by use of muskmelon as trap crop (T₁) and hand picking of RPB adult (T₂). All three treatments are environment friendly. The most effective insecticide was Nitro 505 EC @ 1 ml/L, which was followed by Foratap 4G @ 4 g/plant. Use of muskmelon as trap crop is an environmentally safe cultural technology for the farmers. It would be feasible for large scale farming as well as small farming and home-stead gardening in Bangladesh.
