TLDR
The solubilized entomotoxin of Bacillus thuringiensis subsp.Abstract:
The solubilized entomotoxin of Bacillus thuringiensis subsp. israelensis killed adult male and female mosquitoes of several genera and of various physiological states when it was administered orally. Adult mosquito mortality was further influenced when the preparation was contained in sucrose solution. The potential implication for the control of adult mosquitoes is discussed. Imagesread more

Effects of sugar deprivation on the host-seeking behaviour of gravid Aedes aegypti mosquitoes
TL;DR: Although the initial step of host-seeking inhibition is ovarian dependent, implantation of ovaries from starved females into sugar-fed ovariectomized hosts demonstrated that this step is not affected by starvation.

The fate of Bacillus thuringiensis var. israelensis in B. thuringiensis var. israelensis-killed pupae of Aedes aegypti.
TL;DR: It is demonstrated that the bacterium is capable of inducing death of Aedes aegypti pupae and of recycling in the resulting carcasses of B. thuringiensis var.

Purification of the mosquitocidal and cytolytic proteins of Bacillus thuringiensis subsp. israelensis.
TL;DR: Mixtures of the two purified proteins were significantly more toxic to mosquito larvae than was either protein alone, and it is likely that both the mosquitocidal and the cytolytic protein play roles in the overall insecticidal action of the parasporal crystal produced by this bacterium.

Integration of Bacillus thuringiensis H-14 formulations and pyriproxyfen for the control of larvae of Aedes aegypti and Aedes albopictus
TL;DR: Water-dispersible Bti granules provided effective initial control activity against Ae.

Bacillus thuringiensis var israelensis crystal delta-endotoxin: effects on insect and mammalian cells in vitro and in vivo
Wendy E. Thomas,David J. Ellar +1 more
TL;DR: With the exception of the Lepidopteran cell line, Choristoneura fumiferana 63 CF1, this soluble crystal delta-endotoxin protein showed no in vitro or in vivo toxicity, and no haemolytic activity.

Insect-flower associations in the high Arctic with special reference to nectar'
TL;DR: It is concluded that flowers and floral groups are important as aggregation centres for insect populations in this environment with competition between flowers for pollinators rather than among pollinators for nectar.

TL;DR: Despite antitryptic factors which are known to occur in different titres in vertebrate bloods, no inhibition was observed in vivo when proteases were recorded after enemas of blood or plasma from several hosts into Aedes aegypti, Anopheles quadrimaculatus, and Culex pipiens quinquefasciatus.
