ABSTRACT
The studies on pest complex were conducted during rabi season at Research Farm of Janta Vedic College, Baraut (Baghpat) in Western Uttar Pradesh revealed that 13 species of insect pest were recorded to infest the mustard crop. The mustard aphid (Lipaphis erysimi kalt.) was found as a keypest of mustard crop during the study period. Painted bug (Bagarda cruciferarum Kirk.) was found as a minor pest, first at seeding stage and second at harvesting state when the crop was in maturing stage. The saw fly (Athalia lugens proxima Klug.), pea leaf miner (Chromatomyia horticola Goureau.) and flea beetle (Phyllotreta cruciferae Goeze) were also found as a minor pest with irregular occurrence during the study period.

INTRODUCTION
Indian Mustard, Brassica juncea (L) Czan is an important oilseed crop in India having an area of about 6.4 m ha with a production of 8.02 mt. and productivity is 1262 Kg/ha (Patel and Singh, 2017). India is ranked third after Canada and China Sharing about 11.0% of the global rape seed production of oil seeds in India during 2018-19. Bakhetia ad Sekhon (1984) recorded 38 insect pest from rapeseed mustard crops. The crop is attacked by several insect pests which cause the major problem to mustard growers. The present study will help to know the pest complex in the agroclimatic conditions of Baraut (Baghpat) to find out their suitable management.
MATERIALS AND METHODS
Field experiment was carried out during rabi season of 2022-23 at Research Farm of Janta Vedic College, Baraut (Baghpat) UP to study the pest complex on mustard. The mustard variety Varuna was sown in Randomized Block Design in the plot size of 4m x 3m having row to row and plant to plant spacing as 30 and 15 cm respectively. The crop was grown with recommended agronomical practices. The observation of insect pest was taken either daily or at an Interval of 1-2 days.
RESULTS AND DISCUSSION
The mustard crop was found to be infested by 13 species of insect pests at different phases of growth, among these pests mustard aphid (Lipaphis erysimi kalt.) was found as a major pest. Painted bug
(Bagrada cruciferarum Kirk.), sawfly (Athalia lugens proxima Klug.) and pea leaf miner (Chromatomyia
horticola Goureau) were found as a minor pests of repeseed-mustard crop. The mustard aphid was found as the key pest and remains active during vegetative, flowering and pod formation stage. The painted bug damaged the crop, first in the seeding stage and than at the pod stage. The nymphs and the adults sucked sap from leaves shoots, inflorescence or pod on the plants. The sawfly was found at the seeding stage. The flea beetle (phyllotreta cruciferae Goeze) was recorded as minor pest of rapeseed mustard. The other pest such as cabbage butterfly (Pieris brassicae Linn.), diamond back moth (Plutida xylostella Linn.) cut worm (Agrotis segetum Dennis & Shiff.), bihar hairy caterpillar (Diacrista obliqua Walker), green peach aphid (Myzus persicae Hub) etc.were found of minor importance but some times they may damage the crop moderately. The other pests appeared on the crop as occasional pests. (Table 1) Rai (1976) recorded 24 insect species while Bakhetia and Sekhon (1984) recorded 38 insect pests infesting recorded by Chaudhary and Pal (2006), singh et al (2007), Bakhetia and Arora (1993) and Purwar et al (2004) These results support the present investigation with minor variation which may be due to the agroclimatic conditions, and due to the difference in the time of sowing.
