The consumption of vegetable in Bangladesh is about 50 g day-1 capita-1 which is the lowest amongst the countries of South Asia and South Africa (Rekhi, 1997). But dietitian recommended a daily allowance of 285 g vegetable for an adult person for a balance diet (Ramphall and Gill, 1990). Here people have been suffering from inadequate supply of vegetables since decades. Total annual vegetable production of Bangladesh 1.6 million M tones in winter and 1.5 million M tones in summer season while the cultivated area of Bangladesh 0.47 million acres in winter and 0.65 million acres in summer season (BBS, 2012). As a result, chronic malnutrition is often seen in Bangladesh. Of the total production, less than 25% is produced during Kharif season and more than 75% is in the Rabi season (Anon., 1993).

    © 2018 JETIR December 2018, Volume 5, Issue 12 www.jetir.org (ISSN-2349-5162) Management of pumpkin beetle in cucurbitaceous crop: A review S. K. Gharde* Assistant Professor, School of Agriculture, Lovely Professional University, Punjab Abstract Among all the Coleopteran insect pests red pumpkin beetle (Aulacophora foveicollis) is the major one in cucurbitaceous crop. It is capable to cause 30 to 100% yield losses in various cucurbits crops. There are different chemicals which are effective for the management of red pumpkin beetle in cucurbitaceous crop. Different researcher reported that the application of chemicals like carbaryl, monocrotophos most effective against red pumpkin beetle. Carbofuran @ 0.5% a.i./ha as soil application are found to be most effective for red pumpkin beetle during seedling stage. Soil application and seed treatment of carbofuran in granules form has found most effective against red pumpkin beetle without any side effects on seed germination in muskmelon and bottle gourd. Key words: Beetle, Management, cucurbits, carbaryl, monocrotophos, carbofuran Introduction Cucurbitaceous are the most common and important vegetable crops in India and have good nutritional and medicinal value. There are numbers of insects which attacks on cucurbitaceous crop. Among those insects A. foveicollis is the major insects of cucurbitaceous crop. It is capable to cause 30 to 100% yield losses in various cucurbits crops (Gupta and Verma, 1992). Doharey, (1983) reported more than 81 plant species includes Pumpkin, snake gourd, squash, bitter gourd, water melon, sweet gourd, cucumber, bottle gourd etc. Singh et al., (2000) reported that the minimal damage caused by red pumpkin beetle in bitter gourd (Momordica charatia) and on the other hand bottle gourd (Lagenaria siceraria), cucumber (Cucumis stivus), muskmelon (Cucumis melo) and long melon (Cucumis utissimus) were highly preferred as a host .

Currently, the occurrence of pests and diseases is one of the major constraints in MMT cultivation. Thus, the study on pest and disease incidence at different growth stages of MMT plants were conducted as very little information about it on MMT has been reported. Collection of pest samples and observation on diseases incidence were conducted for eight weeks following the growth stages of MMT. A total of 176 individuals belonging to six orders, 15 families and 37 species of insects were collected throughout this study. Results revealed that red pumpkin beetle (RPB) (Raphidopalpa foveicollis: Chrysomelidae: Coleoptera) was the most dominant pest found on almost all growth stages of MMT. RPB were recorded in Week 1 until Week 5 with infestation on the MMT leaves and stems that caused severe damage on the plants. The second dominant pest was melon worm (Diaphania hyalinata: Crambidae: Lepidoptera) which was more abundant during foliage expansion stage (Week 3), followed by leaf miner fly (Liriomyza trifolii: Agromyzidae: Diptera) which was mostly found during the fruit maturation stage of MMT plants.

KHAN Department of Entomology, Patuakhali Science and Technology University, Dumki, Patuakhali, Bangladesh Abstract To find out preferred cucurbit host(s) of the pumpkin beetle and to determine the susceptibility of ten different cucurbits to the pest, a trial was conducted under field conditions. The results revealed that the most preferred host of the red pumpkin beetle (RPB) was muskmelon, which was followed by khira, cucumber and sweet gourd, and these may be graded as susceptible hosts. Bitter gourd, sponge gourd, ribbed gourd and snake gourd were least or non preferred hosts of RPB and these may be graded as resistant hosts. Other two crops, the bottle gourd and ash gourd were moderately preferred hosts of the insect and these may be graded as moderately susceptible hosts. The order of the most preferred host of the blue pumpkin beetle may be shown as bitter gourd> ribbed gourd> sponge gourd. Of these cucurbits, population of blue pumpkin beetle was much higher than that of red pumpkin beetle. The hosts most preferred to RPB are less preferred or not preferred to the blue pumpkin beetle. The field trials revealed that the order of preference of RPB for ten tested cucurbit hosts was muskmelon> sweet gourd> cucumber > khira > ash gourd > bottle gourd > sponge gourd ≥ ribbed gourd ≥ snake gourd > bitter gourd. Key words: Host preference, pumpkin beetle, cucurbits Introduction The family Cucurbitaceae comprises more than 700 species of plants in about 90 genera (York 1992).
