Six provenances of P. pinnata were screened namely Raipur, Ambikapur, Jabalpur, Nainpur, Zaheerabad and Keesaragutta. Fortnightly recorded of various insect pests along with the number of their associated natural enemies were also recorded. The major insect pests were the common banded awl, leaf webber, leaf blotch miner, pod borer, leaf hopper, leaf eating beetle, mealy bugss and green lace wing, mantis along with some species of spiders were observed as the natural enemies. Maximum population of common banded awl, Hasora chromus was recorded as 17.00 larvae/twig on provenance Jabalpur. Maximum infestation (36.3%) seeds were by pod borer, Ephestia sp. was recorded on Nainpur. Population of leaf webber was maximum (3.92 larvae/ twig) on Jabalpur and Keesaragutta, blotch miner (8.41 blotches/leaf) on Jabalpur, leaf eating beetles (5.25 beetles/twig) Zaheerabad, leaf hoppers 5.58 (nymphs and adults/ leaf) on Keesaragutta, mealy bugss (6.50 nymphs and adults/twig).
Seventeen genotypes of spine gourd were screened against cucurbit fruit fly (Bactrocera cucurbitae) under natural field conditions with the collaboration of AICRP Potential Crop at Research-cum-Instructional Farm of IGKV, RMD College of Agriculture and Research Station Ambikapur in northern hilly region of Chhattisgarh during kharif 2017-18. Among the all, none of genotype was performed free from fruit fly infestation. Only the genotype Indira Kankoda (IK-1) was recorded as "resistant" showing of 16.30 and 17.43 percent fruit infestation (on fruit number and weight basis). However, the genotype RMF-7-P-1 was assigned as "susceptible" with 51.06 and 53.00 percent infestation respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
