Azine Derivatives as a New Generation of Insect Growth Regulators
CHIMIA, 2003 A new generation of insect-growth-regulator insecticides, the azines, are presented. They inhibit the chitin biosynthesis process and are active against lepidopteran pests. Their synthesis and a structure–activity relationship will be discussed.

Nuclear processes associated with plant immunity and pathogen susceptibility [PDF]
, 2015 Plants are sessile organisms that have evolved exquisite and sophisticated mechanisms to adapt to their biotic and abiotic environment. Plants deploy receptors and vast signalling networks to detect, transmit and respond to a given biotic threat by ...

Studies on Insect Growth Regulating Substances with Insect Cell Cultures [PDF]
Agricultural and Biological Chemistry, 1985 The sensitivity of cultured insect cells to a moulting hormone depended on their origin. Cell proliferation of cell-line C6/36, which originated from an Aedes albopictus larva, was suppressed by high concentrations of 20-hydroxyecdysone but was greatly promoted by low concentrations.

Effect of insect growth regulators on the development of Helicoverpa armigera
Environment Conservation Journal, 2010 In laboratory study various developmental changes were exhibited by Helicoverpa armigera by the treatment of different insect growth regulators (IGRs) i.e. lufenuron, novaluron and UPI-106.

Endocrine remodelling of the adult intestine sustains reproduction in Drosophila. [PDF]
, 2015 The production of offspring is energetically costly and relies on incompletely understood mechanisms that generate a positive energy balance. In mothers of many species, changes in key energy-associated internal organs are common yet poorly characterised

Improving the availability of biopesticides : an interdisciplinary research project [PDF]
, 2008 There is a need for new, biologically-based crop protection products to serve as alternatives to or to complement synthetic chemical pesticides. An interdisciplinary research team from the natural and social sciences considered whether regulatory ...

Four-way regulation of mosquito yolk protein precursor genes by juvenile hormone-, ecdysone-, nutrient-, and insulin-like peptide signaling pathways. [PDF]
, 2014 Anautogenous mosquito females require a meal of vertebrate blood in order to initiate the production of yolk protein precursors by the fat body. Yolk protein precursor gene expression is tightly repressed in a state-of-arrest before blood meal-related ...

COMPARATIVE EFFICACY OF THREE INSECT GROWTH REGULATORS ON THE DEVELOPMENTAL STAGES OF CULEX TRITAFIVIORHYNCHUS [PDF]
Journal of Veterinary and Animal Sciences, 2010 The effect of three Insecf Growth Regulators (Diflubenzuron, Methoprene and Btf) was studied on the eggs, fourth stage larvae and pupae of Culex tritaeniorhyncus. The LCso of the insecticides was minimum when applied against 4"' stage larvae than on
