Sentence examples for microbial insecticides present from inspiring English sources

Could microbial insecticides present a risk to other species through host-range evolution?

The action of microbial insecticides is often specific to a single group or species of insects, and this specificity means that most microbial insecticides do not naturally affect beneficial insects (including predators or parasites of pests) in treated areas.

The microbial insecticides applied were Bacillus thuringiensis var.

These programs make the assumption that natural insecticides present less risk to the environment than synthetic insecticides, aligning with public opinion [8] and influential scientific papers purporting greater sustainability of organic practice [9].

This approach includes the use of microbial insecticides, as well as many specific uses of predators of parasites and parasitic insects.

Greenhouse populations are frequently under strong selection from the use of the microbial insecticides based on the toxin produced by Bacillus thuringiensis (Bt) with resulting increased selection for resistance in some cases (Janmaat and Myers 2003; Franklin and Myers 2008).

However, within specific pathogen groups, other traits are also seen as restricting the development and adoption of microbial insecticides, in particular their ability to cope with environmental stresses and factors that relate to their production, storage, and dissemination.

In Ohio, 27,000 acres of woodlands have been sprayed with Bacillus thuringiensis, or Bt, a microbial insecticide that kills butterflies and moths in the larval stage.
