“…This indicates that the active principles present in the particular solvent extracts inhibit larval feeding behaviour or make the food unpalatable or the substances directly act on the chemosensilla of the larva resulting in feeding deterrence (antifeedant). These findings are in agreement with the earlier reports of Jeyasankar et al [16] . Several authors have reported that plant extracts possess similar type of antifeedant activity against lepidopteran pests [17][18][19][20] .…”

“…Antifeedant effects of various Solanum spp. extracts were reported (Castillo et al, 2009;Chopa et al, 2009;Devanand and Rani, 2011;Jeyasankar et al 2012). Ladybirds might migrate towards these areas, since low concentration of glycoalkaloids may be a signal for the presence of herbivores, which are the prey of these usually predatory insects.…”

Repellent or attractant activity of extracts obtained from Solanum tuberosum and Lycopersicon esculentum leaves were tested against Tenebrio molitor (Coleoptera: Tenebrionidae) and Harmonia axyridis (Coleoptera: Coccinellidae). Different developmental stages of the insects (larvae of different age and imagoes) were exposed to the extracts which is present in the substratum. Extracts were used in different concentrations of 1, 10, 100 or 1000 ppm. Distilled water was used as control. In this study, we observed migration of the insects towards the exposed area especially with lower concentrations of extracts which is taken as attractant activity. In other cases, insects showed migration towards control areas which is taken repellent activity. The reaction differed between both insect species, as well as between younger, older larvae and adults of T. molitor. Therefore we infer from this study that both plants may be a source of substances which will be used in insect pest management for plant protection.

“…Also, sugars and amino acids could interfere with the perception of feeding stimulant receptors, while others may cause erratic bursts of electrical impulses in the nervous system resulting in feeding deterrence. (Jeyarajan et al, 1990;Jeyasankar et al, 2012;Jeyasankar et al, 2014) The main FA components represented as OL (C18) and LAME (C19) of the crude extract had a significant very low antifeedant effect only in high concentrations and particularly seemed to be attractive in very low concentrations. This findings were agree with (Ganesan et al, 2006) observations that Longer-chain-length FAs (C12-C18) were attractive at lower levels but repellent at higher levels for Aedes aegypti L. oviposition.…”

Toxicity and antifeedant effect of hexane apricot kernel extract (HEAK) and its gas chromatography-mass spectroscopy (GC-MS) identified fatty acid (FA) components palmitic acid (PA), Oleic acid (OL) and FA derivatives (Linoleic acid methyl ester (LAME)) were assessed against 2 nd and 4 th instar larvae of Spodoptera littoralis under laboratory conditions. Methoxyfenozide (Runner 24% SC ® ) was used as reference insecticide to (HEAK) and its components. The results were statistically analyzed by probit analysis to calculate (LC 50 ) of mortality and the concentrations caused 50% of antifeedant index (AI 50 ) after 24, 48 and 72 hrs of exposure. The results of toxic and antifeedant effects showed the definite prevalence of HEAK versus its FA components against the two instar larvae of S. littoralis throughout 72 hrs of exposure. However the toxic initiation of the extract and its components paced methoxyfenozide by the first 24 hrs of exposure, methoxyfenozide still owned a superior toxicity and antifeedant response on the treated larvae. This work has been associated with some physiological tests including haemocytes count and corpora allata (CA) activity.
