Abstract/ Executive Summary:

The research was carried out in the field and laboratory of the Department of Entomology, Bangladesh Agricultural University, Mymensingh during December, 2011 to October, 2012 on the effect of host and temperature on oviposition and food consumption of red pumpkin beetle (RPB), Aulacophora foveicollis (Lucas). Three cucurbitaceous vegetables viz. sweet gourd (BARI Misti Kumra-1, BARI Misti Kumra-2 and Local Misti Kumra), bitter gourd (BARI Karola-1, Taj Karola-88 and Local Karola) and bottle gourd (BARI Lau-3, BARI Lau -4 and Local Lau) were selected to conduct this research. Host plants had the clear role on the feeding of red pumpkin beetle. Due to feeding of A. foveicollis, the highest percentage of weight loss of leaf was recorded from sweet gourd among the selected cucurbits while Local Misti Kumra was found the most preferred host by beetle considering their feeding efficacy compared to other varieties. Results also showed that temperature had a profound effect on the oviposition and food consumption by A. foveicollis while 30oC was the optimum temperature both for oviposition and food consumption for all selected cucurbits and their varieties.

Start Date: 00-12-2011

End Date: 00-10-2012

Program Area: Pest Management

Commodity: Insects

Objectives:

i. To measure the food consumption of the beetle among different crops and varieties of cucurbits in the laboratory

ii.To investigate the effect of temperature on the feeding and oviposition of the adult beetle

Methodology:

Experiments were conducted in the laboratory of the Department of Entomology, Bangladesh Agricultural University (BAU), Mymensingh during December, 2011 to October, 2012. The test plants of three cucurbitaceous vegetables such as sweet gourd (BARI Misti Kumra-1, BARI Misti Kumra-2 and Local Misti Kumra), bitter gourd (BARI Karola-1, Taj Karola-88 and Local Karola) and bottle gourd (BARI Lau-3, BARI Lau -4 and Local Lau) were grown in the field laboratory, Department of Entomology with maintaining all recommended agronomic practices to conduct the research work for which the quality seeds were collected from Bangladesh Agricultural Research Institute (BARI), Gazipur and seed stores of Mymensingh town. To estimate the food consumption, two adult beetles were released in each petri dish containing a leaf each of nine varieties. Three petri dishes were maintained for each variety. Fresh leaves of plants were supplied daily. The cut end of leaf petiole was provided with water soaked cotton pad to prevent withering of leaf. Food consumption was determined by measuring the weight loss of consumed leaf by the beetle using an electric balance. This experiment was carried out up to seven days. Weight loss of leaf was calculated as percentage. Percentage weight loss was calculated by deducting the % weight loss of fresh leaf from the eaten leaf by the beetle. Pooled means for three crops calculated from the mean values of three varieties of each crop. To study the influence of temperature on the food consumption and oviposition of the beetle, experiments were conducted at three distinct temperatures viz. 15ºC, 25ºC and 30ºC on three nine varieties of cucurbitaceous vegetables with three replications for each in the laboratory using an incubator. Two adult red pumpkin beetles (male + female) were released in each Petri- dish with leaves as food and then these petri dishes were put inside the incubator. The experiment was replicated three times. The quantity (mm2) of food consumed by adult beetles per day was measured using square millimeter graph paper simultaneously the number of eggs laid on each variety was counted. Data obtained from different experiments were analyzed using a statistical package program MSTAT-C and the mean values were ranked by Duncan's Multiple Range Test (DMRT).

Achievement/Findings:

Host crops and their varieties had a great role on the food consumption of red pumpkin beetle. Among three crops and nine varieties sweet gourd and variety Local Misti Kumra had the highest effect on the highest food consumption of red pumpkin beetle. Bitter gourd and the variety BARI Karola-1 had the lowest role on the food consumption of RPB. Temperature had a profound effect on the food consumption as well as oviposition of RPB. It was also found that 30ºC was found the optimum temperature for food consumption and oviposition for the beetle considering the selected cucurbits and their varieties.
