“…Fresh field bean leaves were provided at 24 h intervals by replacing the previous ones, and a moist piece of cotton was wrapped around the cut end of the petiole of leaves to prevent desiccation of leaves. The aphids were not reared on L. sativus as the insects might be adapted to the volatiles of L. sativus , which may result in bias of A. craccivora in olfactometer bioassays 23,24 . Newly emerged adult viviparous females were starved for 2 h before insect feeding treatments.…”

“…We have previously shown that long-chain alkanes and free fatty acids from leaves and flowers of L. sativus serve as shortrange attractants and nymph laying stimulants to the viviparous aphid, A. craccivora. 23,24 To date, volatiles from L. sativus plants attracting A. craccivora have not been explored. Therefore, it is of considerable interest to identify and quantify volatile organic compounds (VOCs) from L. sativus plants that attract A. craccivora.…”

BACKGROUND: The viviparous aphid Aphis craccivora Koch (Hemiptera: Aphididae) is a serious threat to the crop yield of Lathyrus sativus L. (Fabaceae), commonly known as grass pea. The synthetic insecticides applied to control this insect pest are not safe for the environment. Hence, it is necessary to find volatile organic compounds (VOCs) from two cultivars [BIO L 212 Ratan (BIO) and Nirmal B-1 (NIR)] of L. sativus plants causing behavioral preference of A. craccivora. RESULTS: The VOCs from undamaged (UD), insect-damaged (ID) [plants on which 50 or 100 adults of A. craccivora were fed for 4 h (ID 50 or ID 100)], and mechanically damaged (MD) plants were identified and quantified by gas chromatography-mass spectrometry and gas chromatography-flame ionization detection analyses, respectively. Total VOCs were higher in ID plants compared to UD plants of each cultivar. However, total VOCs were higher in NIR cultivar compared to BIO cultivar for both UD and ID plants. Benzyl alcohol was predominant in volatile extracts of all treatments. In Y-tube olfactometer bioassays, females showed preference towards volatile extracts of UD, ID, and MD plants of each cultivar compared to the control solvent (CH 2 Cl 2). Insects preferred certain synthetic blends comparable to volatile extracts of UD, ID, and MD plants of each L. sativus cultivar against the control solvent. CONCLUSION: Females preferred a synthetic blend of benzyl alcohol, 1,3-diethylbenzene, thymol, and 1-hexadecene at ratios of 142.49: 62.03:1.18:1 dissolved in 25 ∼L of CH 2 Cl 2 in olfactometer bioassays, which could be used in developing lures to control this insect pest.

“…The leaf surface of the selected bre crops represents different patterns of epicuticular wax deposition as in other studies The short-distance behavioural responses of different insects have been previously evaluated through different olfactometers (Vshaped, multi-tube, six-arm, Y-tube, etc. (Koschier et al 2000;Mitra et al 2020;Roy, 2019a;Turlings et al 2004). The Y-tube olfactometer used in present bioassays revealed clear olfactory responses of S. obliqua females to n-alkanes and FFAs present in leaf waxes of three bre crops.…”

Behavioral responses of a generalist pest, Spilosoma obliqua Walker (Lepidoptera: Arctiidae), towards the leaf surface wax chemicals of three types of jute crops (white jute, Corchorus capsularis, tossa jute, C. olitorious,, and mesta jute or kenaf, Hibiscus cannabinus [Malvaceae]) and their implications in pest management was studied under laboratory conditions. The GC-MS and GC-FID analyses of the jute leaf epicuticular waxes indicated the presence of 27 n-alkanes, having chain lengths from n-C14 to n-C36 and 14 free fatty acids (FFAs) having chain lengths from C12:0 to C22:0. Among the identified n-alkanes and FFAs of selected jute cultivars n-C34 (144.397±6.971 µg leaf−1) and C16:1 (37.034±0.848 µg leaf−1) of tossa jute leaves were most abundant. The host preference (white jute> tossa jute > mesta jute) of S. obliqua was evaluated simultaneously by olfactory, visual, and tactile recognition, as valid for other lepidopteran species. For olfaction [females], oviposition [gravid females], and feeding [larvae]) in S. obliqua, the most stimulating combined-synthetic-mixture of epicuticular wax components was represented by 4 n-alkanes (n-C16, n-C18, n-C20, n-C22) and 5 FFAs (C16:1, C16:0, C18:0, C20:0, C22:0) in mixture at leaf equivalent (µg leaf−1) amounts (195.209±2.950 µg, 119.777±1.857 µg, and 50.567±3.508 µg, respectively) in white jute, tossa jute, and mesta jute, respectively. Thus, the present study suggests that the synthetic blends of 4 n-alkanes and 5 FFAs of respective jute crops can be used as lures to develop baited trap as a part of integrated pest management (IPM) of S. obliqua for sustainable jute cultivation.
