ABSTRACT
A six year field study was conducted from 2001–2002 to 2006–2007 at Punjab Agricultural University, Ludhiana, India to
study the losses in seed yield of different
Brassica
species (
B. juncea, B. napus
,
B. carinata
,
B. rapa
and
Eruca sativa
) by the infestation
of insect pests. The experiment was conducted in two different sets viz. protected/sprayed and unprotected, in a randomized block
design, with three replications. Data on the infestation of insect pests, and seed yield were recorded at weekly intervals and at harvest,
respectively. The loss in seed yield, due to mustard aphid and cabbage caterpillar, varied from 6.5 to 26.4 per cent.
E. sativa
suffered
the least loss in seed yield and harboured the minimum population of mustard aphid (2.1 aphids/plant) and cabbage caterpillar
(2.4 larvae/plant). On the other hand,
B. carinata
was highly susceptible to the cabbage caterpillar (26.2 larvae/plant) and suffered the
maximum yield loss (26.4%).
