Ludwigia adscendens (L.) Hara, Ludwigia parviflora Roxb., and Ludwigia octovalvis (Jacq.) Raven (Onagraceae) are abundant weeds in rice fields in India. These weeds compete with rice for resources in fields and this results in reduction of grain yield. Altica cyanea (Weber) (Coleoptera: Chrysomelidae) is a biocontrol agent of the three rice-field weeds. Hence, it is relevant to study host preference of A. cyanea using volatile cues of these three weeds. Therefore, we attempted to identify volatiles from leaves of the three Ludwigia species attracting A. cyanea, which could be used as an attractant during early emergence of the weeds in rice fields. In Y-tube olfactometer assays, A. cyanea females were more attracted to natural volatiles of plants after 48 h of feeding by adults than to volatiles of undamaged plants. The volatile organic compounds from undamaged plants, and plants after 6 and 48 h of feeding by A. cyanea were identified and quantified by gas chromatography and mass spectrometry (GC-MS) and GC-flame ionization detection (FID), respectively. In total, 25, 29, and 29 volatile compounds were detected in headspaces of undamaged L. adscendens, L. parviflora, and L. octovalvis, respectively, whereas 32, 35, and 34 compounds, respectively, were detected after 48 h of feeding by A. cyanea. Methyl jasmonate predominated among the volatile compounds in all treatments, but this compound was not attractive to A. cyanea. Females were attracted by synthetic blends of 3-hexanol, a-pinene, linalool oxide, and phytol in amounts mimicking those in each of the three Ludwigia species after 48 h of feeding by A. cyanea. The blends mimicking L. adscendens and L. parviflora included geraniol, whereas the blend mimicking L. parviflora also included 1-tridecanol. These synthetic blends may be helpful to monitor A. cyanea in biocontrol programmes.

“…This hypothesis must be rejected since linalool did neither stimulate nor diminish egg laying by D. radicum in field conditions, at least at the concentration used in our trial. It is therefore dubious that linalool is the main factor responsible for the high attractiveness of Chinese cabbage for this pest, unless its efficiency as an attractor depends on its interaction with the rest of the Chinese cabbage blend (Mukherjee et al 2015).…”

Artificially applied plant volatile organic compounds modify the behavior of a pest with no adverse effect on its natural enemies in the field

The use of volatile organic compounds (VOCs) derived from plants to manipulate insect pest behavior can be applied in an integrated pest management strategy (IPM) using a combination of attractive and repulsive stimuli. The ''push-pull'' strategy was developed on this idea in order to disturb and modify the distribution and abundance of pests to protect crops and reduce the use of agrochemicals. This field experiment investigates, in a ''push-pull'' context using broccoli as a target crop and Chinese cabbage as a pull component, the stimulo-deterrent effect of five synthetic VOCs (dimethyl disulfide, linalool, geraniol, eucalyptol and citronellol) on the oviposition of the cabbage root fly Delia radicum. With the exception of linalool, all compounds tested had a significant effect in the field and eucalyptol showed the most promising results, reducing oviposition on broccoli by 45 %. Moreover, eucalyptol was the only VOC able to reduce the final infestation of D. radicum, i.e., the number of pupae. The other VOCs reduced oviposition by 20-30 %. No adverse effect of the treatments was found on major parasitoids (Trybliographa rapae and Aleochara bipustulata) and potential predators of D. radicum. This study highlights the potential of VOCs as deterrent stimuli against agricultural pests in the field.

“…Volatiles were collected over 6 h during the light phase of the photoperiod between 10:00 and 16:00 hours. Charcoal‐filtered air was pushed (1 l per min) into one side of the round glass chamber and pulled (0.5 l per min) through a volatile collector trap (150 mm long × 5 mm outer diameter) containing 80 mg of HayeSep Q as an adsorbent (Mukherjee et al., ).…”

“…Our previous studies revealed that A. foveicollis females were attracted by long‐chain alkanes and free fatty acids from M. cochinchinensis leaves and flowers (Mukherjee et al., , , ; Mukherjee & Barik, ), which are low volatile substances that act as close‐range attractants. Long‐range volatiles from M. cochinchinensis leaves attracting A. foveicollis have also been identified (Mukherjee et al., ). However, no studies have established long‐range volatiles from M. cochinchinensis and S. amplexicaulis flowers causing attraction of A. foveicollis .…”

Aulacophora foveicollis Lucas (Coleoptera: Chrysomelidae) is an important phytophagous pest of two cucurbitaceous plants, Momordica cochinchinensis Spreng and Solena amplexicaulis (Lam.) Gandhi. The volatile organic compound profiles from flowers of M. cochinchinensis and S. amplexicaulis were identified and quantified by gas chromatography-mass spectrometry (GC-MS) and GC-flame ionization detector (FID) analyses. Twenty nine and 28 compounds were identified in volatiles of M. cochinchinensis and S. amplexicaulis flowers, respectively. Methyl jasmonate and 3-octanol were the predominant volatiles of M. cochinchinensis flowers, whereas 1-octadecanol and 1-hexanol were most found in the headspace of S. amplexicaulis flowers. Aulacophora foveicollis were more attracted by the flower volatiles of M. cochinchinensis than by those of S. amplexicaulis in a glass Y-tube olfactometer. A mixture of 1-heptanol, linalool oxide, 1-octanol, and nonanal in the proportions present in the headspace of both flower types elicited attraction in the insect. From 25 cm distance, A. foveicollis displayed a preference for artificial flowers of 6.5 cm diameter of S. amplexicaulis flower colour (white) over M. cochinchinensis flower colour (white-yellow). Finally, a synthetic blend (0.43 lg 1-heptanol + 1.44 lg linalool oxide + 0.14 lg 1-octanol + 1.77 lg nonanal dissolved in 25 ll methylene chloride) attracted more beetles when applied in a white artificial flower than when applied in a white-yellow artificial flower from 40 cm distance. This finding may be helpful in the development of traps for pest management strategies.
