Natural insecticides

In the several decades, although neonicotinoids insecticides (typically imidacloprid and thiamethoxam) are widely used and account for 24 % of the total global pesticide production, they still have negative impacts on natural enemies such as kinds of bees as well as adversely affect human health.

Ebook "Basic and applied aspects of biopesticides" consists of five sections namely microbials, botanicals, natural enemies semio- chemicals and biotechnology and equipments, bioinformatics tools and IPM. In Section I, microbial deals with utilization of Bacillus in control of phytonematodes; biological control of pest and diseases with fluorescent pseudomonads, entomopathogenic fungus and entomopathogenic nematodes in pest management, microbial viral insecticides and microbial elicitors to induce immunity for plant disease control in chilli and tomato.

Ebook "Advanced technologies for managing insect pests" among the highlights of this book is the use of novel insecticides acting on a specific site in an insect group and are compatible with natural enemies and the environment. One of such approaches is based on disrupting the activity of biochemical sites acting on transcription factors such as the Helix-Loop-Helix (bHLH) family, anti juvenile hormone (AJH) agents that target JH biosynthetic enzymes, G-protein coupled receptors (GPCR) and bursicon as a target for insect control.

Episparis tortuosalis Moore, 1867 is a serious pest of the Chukrasia tabularis A. Juss which is widely planted in plantations in Vietnam. A biocontrol option to manage this pest is a priority for the forest sector. The objective of this study was to evaluate whether there are potential biocontrol candidates within the E. tortuosalis population.

The invasive nature of Aedes albopictus, a competent vector of dengue, zika, yellow fever, and chikungunya viruses, has spread to many parts of the world. To date, there have been no report regarding the insecticide resistance status of Aedes albopictus populations along the Aegean coasts of Turkey. This study aims to confirm the occurrence of Aedes albopictus populations in the Aegean region of Turkey and test their susceptibility against different insecticide classes. Bioassay for susceptibility to Dikloro difenil trikloroetan (DDT) (4%), propoxur (0.1%), fenitrothion (1%), bendiocarb (0.

Celastrus angulatus Maxim is a kind of crucial and traditional insecticidal plant widely distributed in the mountains of southwest China. Celangulin V is the efficient insecticidal sesquiterpenoid of C. angulatus and widely used in pest control in China, but the low yield and discontinuous supply impeded its further popularization and application.

Knowledge of the natural and potential variation in the tolerance of natural enemies to pesticides may improve the design of robust IPM strategies by extending the role of biological control in some agricultural systems and by increasing the number of available compounds to control diseases and key, secondary, and invasive pests. There are a number of excellent revisions on pesticide resistance in natural enemies.

In this study, linoleic acid is obtained by hydrolysis of soybean oil in ethanol/KOH, separation and enrichment using the urea-fatty acid complex formation method for the fractionation of fatty acids. The process involves the formation at 60 ◦C of a homogeneous solution of free fatty acid and urea in 95% ethanol, followed by cooling the resultant urea complex slurry to -5 ◦C and separation by filtration.

Indiscriminate use of pesticides leads to undesirable load of pesticide residues in marketable vegetables (Kumari et al., 2005) and cause severe ecological consequences like destruction of natural enemy fauna, effect on non-target organisms and directly effect in the form of residues. Hence studies were conducted for the efficacy of different insecticides used commonly and also to establish the dissipation pattern of relatively safer insecticides to fit in pest management strategy.

Neonicotinoid insecticides are widely used nowadays to control many sucking insect-pests in several horticultural crops. They are neurotoxic and systemic in nature and their indiscriminate use may affect both target as well as beneficial insects. They are persistent insecticides and can enter food chain through soil application because of high water solubility. Microbes play an important role in removing toxic insecticides from soil environment and microbial degradation can be considered to be a cost effective mechanism to detoxify the insecticides.

Cyantraniliprole 10% OD at 90 g a.i.ha-1 was significantly effective when sprayed twice at 15 days interval, minimized the sucking pests population and increased cotton kapas yield. Cyantraniliprole 10% OD treatments at 90, 180 and 320 g a.i. ha-1 concentrations had not caused any phytotoxic effects like injury to leaf tip, leaf surface, wilting, vein clearing, necrosis, epinasty and hyponasty. Cyantraniliprole 10% (w/v) OD showed the least effect against the spiders.

Biopesticides have attracted attention in pest management in recent decades, and have long been promoted as prospective alternatives to synthetic pesticides. Biopesticides are natural and good alternative sources of synthetic pesticides. In India, all pesticides, including biopesticides, are regulated under the Insecticides Act, 1968, and the rules framed under it. The act regulates the import, manufacture, transport, sale, distribution, and use of pesticides with a view to prevent any risk to human beings and animals.
