Fate of Pyriproxyfen in Soils and Plants
Since the 1990s, the insect growth regulator pyriproxyfen has been widely used worldwide as a larvicide in vector control and in agriculture to fight a very large number of pests.

Inactivation of the major hemolysin gene influences expression of the nonribosomal peptide synthetase gene swrA in the insect pathogen Serratia sp. strain SCBI [PDF]
Hemolysins are important virulence factors for many bacterial pathogens, including Serratia marcescens. The role of the major hemolysin gene in the insect pathogen Serratia sp.

A salivary gland-secreted peptide regulates insect systemic growth
Insect salivary glands have been previously shown to function in pupal attachment and food lubrication by secreting factors into the lumen via an exocrine way. Here, we find in Drosophila that a salivary gland-derived secreted factor (Sgsf) peptide regulates systemic growth via an endocrine way.

EFFECT OF AN INSECT GROWTH REGULATOR ON NON-TARGET ARTHROPODS IN AN AERIAL APPLICATION AGAINST THE SPRUCE BUDWORM, CHORISTONEURA FUMIFERANA (LEPIDOPTERA: TORTRICIDAE), IN NEW BRUNSWICK, CANADA [PDF]
Airplane application of the insect growth regulator CGA 13353, a juvenile hormone mimic used experimentally against spruce budworm, Choristoneura fumiferana (Clem.), did not drastically reduce percentage parasitism in field samples of that host, but ...

Ferric uptake regulator Fur is conditionally essential in Pseudomonas aeruginosa [PDF]
In Pseudomonas aeruginosa, the ferric uptake regulator (Fur) protein controls both metabolism and virulence in response to iron availability. Differently from other bacteria, attempts to obtain fur deletion mutants of P. aeruginosa failed, leading to the

Herbivore induction of the glucosinolate-myrosinase defense system: major trends, biochemical bases and ecological significance [PDF]
Like many other plant defense compounds, glucosinolates are present constitutively in plant tissues, but are also induced to higher levels by herbivore attack.
