The survey was conducted in selected districts of Kymore Plateau and Satpura Hills zone of Madhya Pradesh (India) to assess the pest status of chilli during 2017-18 and 2018-19 rabi season. Crop was monitored at vegetative, flowering, and fruiting stages in four selected locations (pesticide-free fields) of seven districts viz., Seoni, Jabalpur, Katni, Rewa, Satna, Panna, and Sidhi. The pest spectra included four insect pests and a mite species namely, whitefly, Bemisia tabaci (Gennadius), thrips, Scirtothrips dorsalis Hood, leafhoppers, Amrasca biguttula biguttula (Ishida), fruit-borer, Helicoverpa armigera Hubner, and a mite species, Polyphagotarsonemus latus (Banks); one species of predator, transverse ladybird beetle, Coccinella transversalis Fabricius. The incidence of Leaf curl disease was also observed. The pooled mean population of B. tabaci in Seoni, Jabalpur, Katni, Rewa, Satna, Panna, and Sidhi was 2.86, 2.45, 2.67, 2.79, 2.90, 2.86, and 2.70 individuals/ 10 cm twig, respectively at the flowering stage. Mean population of S. dorsalis was 1.65, 1.48 and 1.34 individuals/ 10 cm twig at flowering stage in Jabalpur, Katni and Panna, while, in Seoni, Rewa, Satna and Sidhi, it was 1.37, 1.35, 1.34 and 1.48 individuals/ 10 cm twig, respectively at fruiting stage. Population of A. biguttula biguttula was 3.14, 3.80, 3.49, 3.14, 3.18, 3.40, and 2.98 individuals/ 10 cm twig at fruiting stage. P. latus population was 0.86, 1.01, 0.92, 0.99, 0.95, 1.13 and 0.96 mites/ leaf at fruiting stage. H. armigera population was 1.13, 0.43, 0.53, 0.62, 1.28, 0.86 and 1.19 larvae/ plant at fruiting stage. Populations of C. transversalis were 1.80, 2.25, 2.32, 1.85, 1.88, 2.36, and 1.67 beetles/ plant at the fruiting stage. The leaf curl (% leaf infestation) incidence was 27.28, 32.43, 33.33, 28.45, 36.03, 25.53, and 36.19 % at the fruiting stage in the mentioned districts of the zone.
An investigation was carried out at Experimental Farm, JNKVV, Jabalpur (MP) during 2016 -2017 to know the population dynamics of major phototactic insect pests using Jawahar light trap in chickpea ecosystem. The present study revealed that gram pod borer was first recorded during 45 th SW in light trap. The activity period of Helicoverpa armigera was noticed from November 2016 to April 2017 with two distinct peaks during 13 th and 14 th SW. The highest peak was observed in 14 th SW. Cutworm was first recorded during 46 th SW in light trap. Three distinct peaks were observed during 4 th , 12 th and 16 th SW with highest peak was observed in 12 th SW. Tobacco caterpillar was also firstly recorded during 46 th SW in light trap with one distinct peak during 13 th SW. Further, the correlation studies revealed that maximum temperature, minimum temperature, sunshine, wind velocity, morning vapor pressure and evaporation showed significant positive correlation whilemorning relative humidity and evening relative humidity, showed negative correlation with Helicoverpa armigera, Agrotis ipsilon (Hufnagel) and Spodoptera litura (Fabricius) moth catches and statistically found significant except wind velocity which wasnon-significant against Agrotis ipsilon (Hufnagel). Rest of the weather parameters were found nonsignificant.
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.
