Abstract
ABSTRACT
Two novel crystal protein genes,
cry30Ba
and
cry44Aa
, were cloned from
Bacillus thuringiensis
subsp.
entomocidus
INA288 and expressed in an acrystalliferous strain. Cry44Aa crystals were highly toxic to second-instar
Culex pipiens pallens
(50% mortality concentration [LC
50
] = 6 ng/ml) and
Aedes aegypti
(LC
50
= 12 ng/ml); however, Cry30Ba crystals were not toxic.
