Abstract:

It is now generally accepted that if nothing is done and insecticide resistance in malaria vectors especially to pyrethroids eventually led to widespread failure of current vector control strategies, the progress achieved so far in reducing the burden of malaria could be reversed. Interventions and operational tactics capable of controlling insecticide resistant malaria vector populations and delaying the evolution of resistance need to be urgently identified and properly investigated. One important insecticide resistance management strategy is to expose vector populations to a combination of

Abstract:

Insecticide resistance mechanisms in five strains of beetles, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) were studied using in vitro and in viva methods. In in vitro studies, the activities of three detoxification enzymes, monooxygenases, GSH S-transferases and esterase s were optimized. Aldrin epoxidase activity and cytochrome P450 level were used to determine the activities of monooxygenases. The model substrates, 3,4-dichloronitrobenzene (DCNB) and 1—chloro -2,4-dinitrobenzene (CDNB) were used to measure GSH S-transferase activities. Five different esterase substrates, p

Abstract:

The growing problem of insecticide resistance is jeopardising current pest control strategies and current insecticide development pipelines are failing to provide new alternatives quickly enough. Metabolomics offers a potential solution to the bottleneck in insecticide target discovery. As a proof of concept, metabolomics data for permethrin exposed Drosophila melanogaster was analysed and interpreted. Changes in the metabolism of amino acids, glycogen, glycolysis, energy, nitrogen, NAD+, purine, pyrimidine, lipids and carnitine were observed along with markers for acidosis, ammonia stress, ox

Abstract:

Due to the increasing resistance demonstrated by insects to conventional insecticides, the need for compounds with novel modes of action is becoming more urgent. Also, the discovery and production of new insecticides is vital as regulations and restrictions on conventional insecticides become increasingly stringent (Casida and Quistad 1998). Research in this area requires screening of many candidate compounds which is costly and time-consuming. The goal of this research was to produce in vitro insect neurons from Sf21 insect ovarian cell lines, which could lead to new high throughput screen

Dengue is the most rapidly spreading vector borne disease. In Thailand, the number of dengue cases increased from 46,829 in 2006 to 76,059 by September 2008 (WHO, 2008). Insecticides play a vital role in controlling this disease but the success of control programmes is continually threatened by the emergence and spread of insecticide resistance in the vector population.

Confirm, Success and Proclaim were evaluated for lepidopterous insect control in lettuce with and without the addition of Mustang 1.5EW. Success and Proclaim used alone were highly efficacious toward cabbage looper and Heliothinae and did not appear to benefit greatly from the addition of Mustang. However, Confirm's activity towards Heliothinae was significantly improved by the addition of Mustang. Additionally, on large framed plants where coverage is difficult, Confirm benefitted from the addition of a pyrethroid for control of loopers.

They are the largest ion channels known made up of four monomers, each 565kDa in size. Mammals have 3 different RyR isoforms, encoded by different genes, while insects express only one isoform of the receptor, which is only 46% similar (at the amino acid level) to its mammalian counterpart(s). RyRs function to regulate the release of luminal Ca2+ stores into the cell cytoplasm and play a key role in muscle excitation-contraction coupling (ECC). The plant alkaloid ryanodine,

Currently 3.3 billion people are at risk of becoming infected with malaria worldwide with over 90% living in sub-Saharan Africa. Recently it was estimated that approximately 131,000 fewer deaths and over 650,000 cases of malaria were averted during the last 15 years. These changes are attributed to the widespread implementation of long-lasting insecticide-treated nets, indoor residual spraying with insecticides, and artemisinin-combined therapeutics across Africa. However, current challenges have resulted in a stalling of progress with insecticide resistance as the most prominent and potential

Control of Lygus depends mainly on just two related chemical classes of insecticides, organophosphates and carbamates.

The aim of this project was to develop azadirachtin as an insecticide that is applied to the soil, using a granular formulation, for root uptake and subsequent systemic plant protection.

This material was used in all subsequent chemical and biochemical studies. To increase the speed of crude extract analysis, a colorimetric technique was assessed to rapidly quantify azadirachtin.
