      Effect of Antibiotics on Larval Susceptibility to B. thuringiensis.. In a previous study, we found that a number of treatments that altered the susceptibility of the gypsy moth to B. thuringiensis also affected the bacterial community in the larvae's midgut (11, 12).To determine whether there was a causal relationship between changes in this community and susceptibility to B. thuringiensis Cited by:

We measured airborne exposures to the biological insecticide Bacillus thuringiensis var. kurstaki (Btk) during an aerial spray program to eradicate gypsy moths on the west coast of Canada. Aerial applications of Foray 48B, which contains Bacillus thuringiensis strain HD1, were carried out on 9 to 10 May, 19 to 21 May, and 8 to 9 June to control European gypsy moth (Lymantria.

The city elected to institute a spraying program to control the moths, using a biological agent, Bacillus thuringiensis (var. kurstaki) or Btk. This soil bacterium enters the digestive system of the moth larva as it feeds on vegetation and then releases toxins that kill it so the reproductive cycle is Size: KB.

Field Tests With Bacillus thuringiensis 19 The importance of having untreated control plots beside or near each treated plot was clearly demonstrated in these tests.

Before treatment two extra check plots (Fig. 1) were established in addition to the original control plot (Plot 1): one near Plots 2 and 3, and one near Plots 4 and 6. Teschke K, Chow Y, Bartlett K, Ross A, van Netten C.

Field Tests With an Aerial Application of Bacillus thuringiensis Charles C. Doane and Stephen W. Hitchcock INTRODUCTION Bacillus tburingiensis var. thuringiensis Berliner was used experimentally in against larvae of the gypsy moth, Porthetria dispar (L), in a Connec- ticut State Forest.

The test was one of several made by entomologists in the. Cry proteins, produced by Bacillus thuringiensis (Bt), are widely used for the control of insect pests in agriculture as spray products or expressed in transgenic crops, such as maize and cotton.

Kaya ). Aerial spray tests conducted in by Secrest and McLane () suggested that B. thuringiensis mixed with molasses was effective against gypsy moth larvae. These encouraging results led us to evaluate one of the new formulations as well as an experimental formulation as aerial sprays against gypsy moth and elm spanworm.

InDipel® (Bacillus thuringiensis Berliner) and Sevin® 4 oil (carbaryl) were applied aerially on a dense population of gypsy moths,Lymantria dispar (L.), to evaluate the effect of these biological and chemical insecticides on gypsy moth larvae and adult parasites. Both insecticides provided excellent protection of foliage (29 % average defoliation) and gypsy moth population Cited by: 8.

Four different types of pathogens are of interest for gypsy moth control, making this the invasive arthropod with the greatest diversity of pathogens being utilized for control.

We measured airborne exposures to the biological insecticide Bacillus thuringiensis var. kurstaki (Btk) during an aerial spray program to eradicate gypsy moths on the west coast of Canada.

We aimed to determine whether staying indoors during spraying reduced exposures, to determine the rate of temporal decay of airborne concentrations, and to determine whether drift. In the mids, Bacillus thuringiensis var. kurstaki replaced chemical insecticides in aerial spraying programs for spruce budworm and other similar insects.

Ongoing improvements. SinceB.t. has been used on nearly 8 million hectares of insect-infested forests. Today it is not only the most effective tool for control of spruce budworm. Bacillus thuringiensis aizawai (Bta) is toxic to honeybees.

Contributor; Bacillus thuringiensis is a bacterium that parasitizes the caterpillars of some harmful moths and butterflies. Spraying or dusting plants with spores of this bacterium appear to be environmentally safe ways to attack such pests as the gypsy moth, the tent caterpillar, and the tobacco hornworm (which also attacks tomatoes).
