Pavela R. (2016): History, presence and perspective of using plant extracts as commercial botanical insecticides and farm products for protection against insects – a review. Plant Protect. Sci., 52: 229–241. Botanical insecticides keep attracting more attention from environmental and small farmers worldwide as they are considered as a suitable alternative to synthetic insecticides. The use of s...

the search for alternative ways of controlling sericultural pests has led to the investigation of plant sources for naturally occurring compounds which may have insect growth regulatory, feeding deterrency, repellency and confusantcy characteristics. more than 2000 species of the families asteraceae, fabaceae and euphorbiaceae are known that possess some insecticidal activity. plants with insec...

To evaluate the effectiveness of selected insecticides and a botanical extract in management of okra shoot and fruit borer, Earias vittella an experiment was conducted in the field Laboratory, Department of Entomology, Bangladesh Agricultural University, Mymensingh during January to May 2011. Effectiveness of two synthetic insecticides (Kinalux 25 EC and Ecofuran 5 G) and a botanical (Neem leaf...

this study was conducted to investigate commercial formulations of insecticides against western flower thrips, frankliniella occidentalis (pergande).the insects were collected from commercial greenhouses of cucumber in varamin, iran. the tested insecticides were diazinon (ec 60%), cypermethrin (ec 40%), fipronil (ec 2.5%), imidacloprid (sc 35%) and a botanical insecticide oxymatrine (kingbo, as...

The impact of three different doses of botanical insecticide derived from the syringa tree, Melia azedarach and the neem tree, Azadirachta indica was tested on the behaviour of the diamondback moth, Plutella xylostella (Linnaeus). Both botanical insecticides had a significant impact on larval behaviour. At higher doses the extracts showed feeding deterrent activity, with larvae preferring the u...

Our analysis of >20000 papers on botanical insecticides from 1980 to 2012, indicates major growth in the number of papers published annually (61 in 1980 to 1207 in 2012), and their proportion among all papers on insecticides (1.43% in 1980 to 21.38% in 2012). However, only one-third of 197 random articles among the 1086 papers on botanical insecticides published in 2011 included any chemical da...

Synthetic and botanical insecticides can have a profound effect on the developmental period, growth, adult emergence, fecundity, fertility, and egg hatch, resulting in effective control at sub-lethal concentrations. This paper investigated sub-lethal concentrations of fenitrothion, lambda-cyhalothrin, and Callitris glaucophylla Joy Thomps. & L.P. Johnson (Cupressaceae) extract to characterize t...

The common pistachio psyllid, Agonoscena pistaciae, is the key pest of pistachio trees in Iran. Both nymphs and adults suck sap from leaves and reduce plant vigor and yield, increase the number of blank, half growth kernel and unsplit nuts and also cause defoliation and buds drop. Detrimental effects of chemical synthetic insecticides and the resistance of common psyllid pistachio to them and t...

Botanical insecticides have long been touted as attractive alternatives to synthetic chemical insecticides for pest management because botanicals reputedly pose little threat to the environment or to human health. The body of scientific literature documenting bioactivity of plant derivatives to arthropod pests continues to expand, yet only a handful of botanicals are currently used in agricultu...

Botanical insecticides presently play only a minor role in insect pest management and crop protection; increasingly stringent regulatory requirements in many jurisdictions have prevented all but a handful of botanical products from reaching the marketplace in North America and Europe in the past 20 years. Nonetheless, the regulatory environment and public health needs are creating opportunities...
