Abstract
Abstract The subject invention concerns a novel and useful insecticide with activity against insect pests of the order Coleoptera. Pests in the order Coleoptera do heavy damage to crops, e.g., corn. The insecticide of the subject invention is a novel B. thuringiensis microbe referred to as B.t. PS86B1, or mutants thereof. The spores or crystals of this microbe are useful to control coleopteran pests in various environments.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim

Claim 3
Dependent Claim
55 words
A process, according to claim 1, wherein said insect pest is contacted with an insect-controlling sufficient amount of B. thuringiensis PS86B1, by incorporating said B. thuringiensis PS86B1 into a bait granule and placing said granule on or in the soil when planting seed of a plant upon which plant insect pest is known to feed.
Claim 4
Dependent Claim
39 words
A process for controlling soil-inhabiting insect pests of the order Coleoptera which comprises (1) preparing a bait granule comprising B. thuringiensis PS86B1, or mutants thereof, spores or crystals; and (2) placing said bait granule on or in the soil.
Claim 5
Dependent Claim
39 words
A process for controlling soil-inhabiting insect pests of the order Coleoptera which comprises (1) preparing a bait granule comprising B. thuringiensis PS86B1, or mutants thereof, spores or crystals; and (2) placing said bait granule on or in the soil.
Claim 6
Dependent Claim
23 words
