Introduction tropical parts of India with an annual production of 1.14 million tonnes from an area Cucumber (Cucumis sativus L.) is a member of 78 thousand hectares and productivity is 15 of Cucurbitaceae family which is comprised of tonnes per hectare (Anon., 2017). Various 118 genera and 825 species (Laila et al., pests attacking the cucumber crop are fruit fly 2015). Among various horticultural crops [Bactrocera cucurbitae Coq.], red pumpkin grown in the world, India is the second largest beetle [Aulacophora foveicollis Lucas], black producer of vegetables in the world, next to pumpkin beetle [Aulacophora atripennis China. Cucumber has been reported as a Fabricius], pumpkin caterpillar [Margaronia commercial cash crop in tropical and sub- indica Saunders], American serpentine leaf 3133 Int.J.Curr.Microbiol.App.Sci (2021) 10(02): 3133-3140 miner [Liriomyza trifolii Burgess], bottle summer, 2019 at Main Vegetable Research gourd moth [Sphenarches anisodactylus Station, Anand Agricultural University, Anand Walker], aphids [Aphis spp.], banded blister (Gujarat) in Randomized Block Design (RBD) beetle [Zonabris postulata Tk. and Mylabris with 8 treatments and 3 replications each phlarata Pall.] and dudhi bugs [Nesidiocoris having gross plot size of 7.5 x 5.0 m and net tenuis Reut. and Gampsocoris spp.].

    © 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 .

  • Pumpkin Beetle (040)
    Pacific Pests, Pathogens and Weeds - Online edition Pumpkin beetle (040) Common Name Pumpkin beetle, red pumpkin beetle Scientific Name Aulacophora species. The identification of the species in the Pacific is uncertain. Aulacophora similis has been recorded from Fiji, Samoa, Solomon Islands, and Tonga. But it is more likely that the species in these countries is Aulacophora abdominalis. Distribution Uncertain. Asia, Oceania. A revision of the species is required to clarify distribution in Oceania Photo 1. Red pumpkin beetle, Aulacophora sp. and elsewhere. Hosts Cucurbits are hosts; common cucurbits are cucumber, melon, pumpkin, watermelon and gourds. Similar species are pests of these plants in Papua New Guinea, Indonesia, the Philippines, Japan, India, and Australia. Symptoms & Life Cycle The life cycle of Aulacophora similis is as follows. Females lay yellow, oval eggs singly or in batches in soil around the base of the host. After 5-15 days, they hatch, and the cream-white young (called 'larvae') burrow into the soil to feed primarily on the roots. Four moults occur over 14-25 days, and then the larvae enter the pupal stage in an earth chamber; this lasts another 7-20 days before the adults emerge (Photos 1-3). Photo 2. Red pumpkin beetle, Aulacophora sp., Females lay up to 500 eggs, and live as long as 10 months. This means there are several eating circles on a leaf. overlapping generations each year. Interestingly, the adult beetles cut discs from the leaves (Photos 2,4&5). It is possible they do this to stop the flow of sap into these discs before feeding on them.
