A REVIEW OF APHIDS (HOMOPTERA: APHIDIDAE) AND THEIR NATURAL ENEMIES IN VEGETABLE CROP ECOSYSTEMS IN JAMMU AND KASHMIR, INDIA | UTTAR PRADESH JOURNAL OF ZOOLOGY

An comprehensive field survey was conducted in different vegetable ecosystems of the Kashmir Valley from 2014 to 2019 to investigate aphid pests and their naturally occurring bio-control agents (parasitoids and predators). A thorough literature review of aphids identified from the Jammu and Kashmir area was also conducted. As a result of these studies, it was determined that in Jammu and Kashmir, 18 species of aphids belonging to 12 genera infest 26 species and 30 varieties of vegetable crops (J&K). Aphis craccivora Koch, Aphis fabae solanella Theobald, Aphis gossypii Glover, Brevicoryne brassicae (Linnaeus), and Myzus persicae are the most common aphid species that infest a wide range of vegetable plant species (Sulzer). It was also discovered that at least 29 insect predators and 17 parasitoids exist naturally in J&K’s vegetable ecosystems to eradicate these aphid species. Adalia tetraspilota (Hope), Coccinella septempunctata L., Cheilomenes sexmaculatus Fabricius, and Hippodamia variegata are some of the most common natural enemies (Goe.), Aphidius matricariae Haliday, Diaeretiella rapae (McIntosh), Chrysoperla zastrowi Sillemi (Esben-Petersen) (Neuroptera: Chrysopidae); Episyrphus balteatus DeGeer, Melanostoma univitatum (Wiedemann), Sphaerophoria scripta (Linnae (Hymenoptera : Braconidae). In conclusion, this study provides a detailed account of aphids and their natural enemies in relation to vegetable crops in the J&K area. This work will be useful in studies involving the development of strategies for an Integrated Aphid Control Program, especially through the use of natural bio-control agents.

LARVAL PARASITOID COMPLEX ASSOCIATED WITH GRAM POD BORER, HELICOVERPA ARMIGERA (HUBNER) IN CHICKPEACROP ECOSYSTEM

Four parasitoids, Campoletis chlorideae (Uchida), Eriborus argenteopilosus (Cameron), Chelonus sp. and an unidentified tachinid fly were recorded parasitizing Helicoverpa armigera under chickpea crop ecosystem at five locations viz. Kewlari, Hatna, Khiriya, Piparia and Gurgawan in Jabalpur (M.P.) during Rabi 2001-02 and 2002-03. Out of which C. chlorideae was predominant and the activities of other three parasitoids were very low and that for a limited period. Fluctuations in parasitization level ranged from 8 to 54% at different locations. Most favourable period for the parasitization was second week of December to first week of January. Two hyper parasitoids of C. chlorideae namely, Brachymeria sp. and Philofena campoletisa (Narendran) were also observed.
