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.
