TLDR
Insecticide research, having passed through several Golden Ages, is now in a renaissance of integrating chemicals and biologicals for sustainable pest control with human safety.Abstract:
Insecticide research led to the first "complete" victories in combatting pests almost 50 years ago with the chlorinated hydrocarbons followed quickly by the organophosphates, methylcarbamates, and pyrethroids--all neuroactive chemicals. This Golden Age of Discovery was the source of most of our current insecticides. The challenge then became health and the environment, a Golden Age met with selective and degradable compounds. Next the focus shifted to resistance, novel biochemical targets, and new chemical approaches for pest control. The current Golden Age of Genetic Engineering has curtailed, but is unlikely to eliminate, chemical use on major crops. Insecticide research, having passed through several Golden Ages, is now in a renaissance of integrating chemicals and biologicals for sustainable pest control with human safety.read more

Manipulating biodiversity in arable farming for better pest suppression: which species and what scale?
TL;DR: In this paper, a network of field margins has been laid down to investigate three main questions: 1. Does an increased biodiversity in a farming system contribute to the suppression of pest populations? 2. How far can field margins be apart? 3. What vegetation diversity is required in order to achieve pest populations suppression? Pitfall traps and yellow water pans in field margins and crops are used to assess antagonists' densities.

Structure and Function Studies of Insect Carboxylesterases
TL;DR: It is suggested that within the context of a youth-services agency using a mobile app to provide information about how to care for vulnerable adults and young people is a viable process.

Insecticide sensitivity of native chloride and sodium channels in a mosquito cell line.
TL;DR: C cultured Anopheles gambiae Sua1B cells express native insect ion channels with potential utility for insecticide screening applications without genetic engineering or other treatments, and the high potency effect was completely inhibited in the presence of tetrodotoxin, a specific sodium channel blocker, suggesting the existence of some type of sodium channel.

Efficacy of Bacillus thuringiensis sprays and cotton cultivars expressing cry proteins in the control of Earias biplaga (Walker) (Lepidoptera: Noctuidae)
TL;DR: Bt spray dosage rate recommended for control of Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) on groundnut and sunflower in South Africa was used in this study and provided between 77 and 88% control of E. biplaga after 10 days.

Effect of cypermethrin on total carbohydrates, glycogen, pyruvate and lactic acid contents in liver and kidney tissues of albino rats.
TL;DR: Pesticides occupy rather a unique position among many chemicals by increasing food and fibre production and by reducing the occurrence of vector borne diseases but their debits have resulted in serious health implications to man and his environment.

Safer and more effective insecticides for the future
John E. Casida,Gary B. Quistad +1 more
TL;DR: The use of synthetic organic insecticides has served for the past half century as the principal means to control insect-borne diseases and minimize losses in food and fibre production from pest insect attack as mentioned in this paper.
