Insecticide resistance governed by symbiotic bacteria

Insecticide Resistance

Insecticide resistance is an increasing problem faced by those who need insecticides to efficiently control medical, veterinary and agricultural insect pests. In many insects, the problem extends to all major groups of insecticides. Since the first case of DDT resistance in 1947, the incidence of resistance has increased annually at an alarming rate. It has been estimated that there are at leas...

Insecticide Resistance and Resistance Management

J. Econ. Entomol. 88(5): 1113-1119 (1995) ABSTRACT Field and laboratory tests were done to determine effects of application technology, plant age, Bacillus thuringiensis (Berliner) subspecies, and rate of application on mortality of 2 populations of diamondback moth, Plutella xylostella (L.). One population was susceptible (Geneva 88) and the other (Loxa b) was resistant to Bacillus tlwringiens...

Symbiotic bacteria induced necrotizing pancreatitis.

CONTEXT Intestinal flora and anaerobes are frequently implicated in causing infectious necrotizing pancreatitis however Bifidobacterium and Veillonella have rarely been isolated as the causative agents. Bifidobacterium and Veillonella are commensal anaerobes which reside in gastrointestinal tract and help deconjugate bile acids. Bifidobacterium is also frequently used in probiotics. CASE REPO...
