Larvicidal and antifeedant activity of some plant-derived compounds to Lymantria dispar L. (Lepidoptera: Limantriidae)

Effect of Artemisia Annua L. On Deterrence and Nutritional Efficiency Of Lesser Mulberry Pyralid (Glyphodes Pylolais Walker) (lepidoptera: Pyralidae)

“…It may also be due to the involvement in the energy transmission process in the central nervous system. A number of researchers have reported on the deterrence effect of plant extracts on insects (Liu et al, 2006;Senthil Nathan 2006;Kostic et al, 2008). Shekari et al (2008) also reported on A. annua extract deterrency against the elm leaf beetle Xanthogaleruca luteola.…”

Antifeeding activity of several plant extracts against Lymantria dispar L. (Lepidoptera: Lymantriidae) larvae

“…For L. dispar, repellent activity is especially common by plants with high alkaloid contents (Dosktotch, 1980). In recent years, antifeeding effects of various plant extracts have been studied by several authors (Zabel et al, 2002;Milanović, 2006;Kostić, 2008;Gvozdenac et al, 2010Gvozdenac et al, , 2011Pavela, 2010). According to Simmonds (2000), more than 6,250 plants have been tested for different insecticidal activities since 1985, while Parkash and Rao (1997) confirmed that about 870 herbal products with insecticidal or repellent antifeeding effect were used in agriculture.…”

“…Gypsy moth (Lymantria dispar L.) belongs to a group of economically most important pests of deciduous forests, but it is also very harmful in orchards and urban greenery, causing defoliation, especially in gradation years and when protection measures are not adequate (Almaši et al, 2004;Mihajlović, 2004Mihajlović, , 2008Tabaković-Tošić, 2006;Kostić et al, 2008;McEwan and Rieske, 2009).…”

“…According to Kamaraj et al (2008) and Kaushik et al (2009), inadequate use of these chemicals has resulted in disturbed biocoenotic balance, outbreaks of some previously less harmful organisms and presence of pesticide residues in soil and watercourses in some regions. To mitigate these consequences, it is necessary to harmonize pest control strategies with the principles of integrated pest management, using selective and less toxic insecticides (Kostić et al, 2008). The Ministries of Agriculture and National Environmental Protection Agencies in most EU countries have developed programmes for reducing the use of conventional insecticides in which preference is given to non-chemical and biological preparations in agriculture, forestry and communal hygiene (Bočarov-Stančić, 2002;.…”

Application of liquid chromatography/mass spectrometry in assessment of potential use of azadirachtins (TreeAzin™) against Asian longhorned beetle

“…Formulated products based on Neem seed extracts contain high levels of different azadirachtin analogues, being the major forms Azadirachtin A and B 8 . These compounds are considered the putative active ingredients for biological activity against insect 35 pests including antifeedent, growth disruption, and reproductive effects as observed in various Lepidopteran and Dipteran pest species 1,9 . Relative to many conventional synthetic pesticides, azadirachtins have innately positive ecotoxicology and 40 environmental fate profiles, exhibiting low toxicity to mammals 10 , facile environmental degradation via photolysis, hydrolysis, and microbial degradation 7,11 and limited to no impacts on non-target organisms [12][13][14] .…”
