HOST PREFERENCE AND INTEGRATED MANAGEMENT OF JASSID, Amrasca devastans (DISTANT), HOMOPTERA: CICADELLIDAE

Abstract

Several studies were carried out at the experimental field of the Entomology Division, Bangladesh Agricultural Research Institute (BARE) Gazipur. Bangladesh during September 2004 to July 2005 to detennine the host prefircncc as well as to develop management tactics ofjassid. Aniwwsca cievastans. Among the six host plants viz, tomato, sweet gourd, country bean. brinjal, okra and cotLon, okra is observed as the most prelerred host ofjassid (number ofjassid/leai was 13.49 = 7.94). followed by brinjal (4.26 ± 2.18) and cotton (3.94 = 0.8$). ft lnstation oijassid was significantly less in two brinjal lines. ISDO06 and BI_l 14 producing highest yield among the tested lines. Those two lines can he considered as the resistant brinjal lines against jassid, A. dci'asrans. Spraying of neem based hio-rationales, neem oil (i 5 mL /liter of water mixed with 1 nil detergent) or neem seed karnel extract (@ 500 gin crushed kernel dissolved in JO liters of water for 24 hours) can effectively control the jassid population on brinjal.
