“…For JA treatments, an individual plant of each T. anguina cultivar (MNS, BAR and POLO) was sprayed with 20 mL of 1 mmol L −1 JA [(±)-jasmonic acid (Sigma-Aldrich, Darmstadt, Germany; purity ≥ 90%)] aqueous solution (hereafter JA MNS, JA BAR and JA POLO) and each plant was kept for 24 h in the laboratory. 30 As a control treatment against JA treated plants, an individual plant of each T. anguina cultivar was sprayed with 20 mL distilled water. After 24 h of JA spray, volatiles from JA treated plants were collected for 4 h. After placing each plant in the closed glass dome, sterilized non-absorbent cotton was encircled in the stem of an experimental plant to avoid damage in the stem by the Teflon base.…”

“…Some of the VOCs in the blends might be omnipresent in diverse plants but the exact qualitative combination and ratios of VOCs fluctuate between plants by which an insect can identify host and stay away from non-host plants. [26][27][28][29][30][31][32] We previously demonstrated that long-chain n-alkanes and free fatty acids present in leaf and flower surface waxes of T. anguina served as short-range attractants and oviposition stimulants in females of D. indica. 33,34 However, VOCs emitting from T. anguina plants causing attraction of adult D. indica have not been explored.…”

BackgroundFirst to third instars of Diaphania indica (Saunders) (Lepidoptera: Crambidae) feed on the lower surface of leaves, while fourth and fifth instars gregariously consume leaves of Trichosanthes anguina L. After defoliating, the caterpillar also attacks flowers and fruits of the plant and finally, results in loss of crop yield. Therefore, behavioral responses of D. indica adults were investigated to volatiles from undamaged (UD), insect‐damaged (ID, plants after feeding by D. indica larvae) and jasmonic acid (JA) treated T. anguina plants.ResultsFemales showed attraction to volatiles of UD and ID plants of three T. anguina cultivars [MNSR‐1 (MNS), Baruipur Long (BAR) and Polo No. 1 (POLO)] in Y‐tube olfactometer bioassays. Females did not show significant negative responses from volatiles of JA treated plants. Females were more attracted to volatiles of ID plants than UD plants. Females showed attraction to volatiles of UD or ID plants compared to JA treated plants. Females were attracted to certain synthetic blends resembling volatiles of insect‐damaged MNS, BAR and POLO plants in olfactometer bioassays. Females could not distinguish among these three certain synthetic blends in olfactometer bioassays. A synthetic blend of 3Z‐hexen‐1‐ol, α‐pinene, hexyl acetate, benzyl alcohol and 6Z‐nonenal at mole ratios of 1.47:1.20:1:1.82:1.21 was prepared at 20 mg/mL dichloromethane and 100 μL when used as lure in funnel traps resulted in the capture of the highest number of D. indica adults in field trails.ConclusionThe earlier five‐component chemical lure could be used in traps in an integrated pest management program of the insect pest, D. indica. © 2023 Society of Chemical Industry.

“…Discriminant function analysis (DA) was conducted using different treatments of three green gram cultivars -UD plants (UD PDM, UD PUSA and UD SAM), ID plants (ID PDM, ID PUSA and ID SAM) and MD plants (MD PDM, MD PUSA and MD SAM) as response variables against the VOCs recorded as explanatory variables to substantiate the differences among green gram cultivars in the context of VOC bouquets using XLSTAT software (Zar 1999). Data obtained on the behavioral responses of S. obliqua towards VOCs were analysed assuming the null hypothesis that the possibility of scores for the test sample(s) or the control solvent is equivalent to 50%, i.e., Chi-square analysis (H 0 : P = 50%) (Koner et al 2022). Insects that remained in the stem of olfactometer were not used for the analysis.…”

Larvae of Spilosoma obliqua Walker (Lepidoptera: Arctiidae) feed on the leaves and owers of green gram [Vigna radiata (L.) Wilczek] and reduce seed yield. Therefore, it is interesting to observe whether undamaged (UD) and insect-damaged (ID, plants after feeding by S. obliqua larvae) plants cause attraction of conspeci c adult moths. Females showed attraction towards volatile blends of UD, ID and mechanically-damaged (MD) plants of three green gram cultivars [PDM 54 (PDM), Pusa Baisakhi (PUSA) and Samrat (SAM)] in Y-tube olfactometer bioassays. Females were more attracted towards volatile blends of ID plants of a particular cultivar than UD plants of the same cultivar. Total amount of volatiles was higher in ID plants than UD plants. Some herbivore-induced plant volatiles − 3Z-hexenal, 1-hexanol, 3Z-hexenyl acetate, 2-octanol and ocimene were attractive to the insect. Females were attracted towards three synthetic blends (µg in 25 µl CH 2 Cl 2 ) comprised − 2.

“…There have been some examples of successful biocontrol agent establishment on Rumex spp., where, in Western Australia, R. pulcher L. were greatly reduced. Moreover, Rumex species are used as food plants by the larvae and/or adults of many Lepidoptera and Coleoptera species, offering a large pool of possible biological control agents to explore [ 41 , 42 , 43 ].…”

Responses of Adult Hypera rumicis L. to Synthetic Plant Volatile Blends

et al. 2022

The behavioral responses of Hypera rumicis L. adults to varying blends of synthetic plant volatiles (SPVs) at various concentrations in lieu of single compounds are reported for the first time. For this study, Rumex confertus plants were treated with two blends of SPVs at different quantities that act as either attractants or repellents to insects. Blend 1 (B1) consisted of five green leaf volatiles (GLVs), namely (Z)-3-hexenal, (E)-2-hexenal, (Z)-3-hexenol, (E)-2-hexenol, and (Z)-3-hexen-1-yl acetate. Blend 2 (B2) contained six plant volatiles, namely (Z)-ocimene, linalool, benzyl acetate, methyl salicylate, β-caryophyllene, and (E)-β-farnesene. Each blend was made available in four different amounts of volatiles, corresponding to each compound being added to 50 µL of hexane in amounts of 1, 5, 25 and 125 ng. The effects of the two blends at the different concentrations on the insects were evaluated using a Y-tube olfactometer. Both sexes of the insects were found to be significantly repelled by the highest volatile levels of B1 and by two levels of B2 (25 and 125 ng). Females were also observed to be repelled using B2 with 5 ng of each volatile. Attraction was observed for both sexes only for B1 at the three lower volatile levels (1, 5 and 25 ng). In additional experiments, using only attractants, unmated females were found to be attracted to males, whereas mated females were only attracted to B1. Both unmated and mated males (previously observed in copula) were attracted only to females.
