“…After adult whiteflies landed on the treated host leaves, they were not able to conduct normal mating behaviours during the remaining 4 days. The observed residual efficacy of acetylated glyceride was consistent with the finding that high control of B. tabaci B was achieved in field studies by applying foliar treatment (0.2%, v/v) at 7-day intervals (Kashima et al 2014).…”

“…tabaci B will eventually settle on an acetylated glyceride‐treated host leaf due to the decrease in residual repellency with time, we found that the number of courting pairs was significantly reduced on treated leaves under laboratory and field conditions (Kashima et al. ). Courting pair formation is known to be necessary for adult whiteflies to mate (Perring and Symmes ).…”

The sweet potato whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), attacks a wide range of vegetables and ornamental plants in the tropics and subtropics. This study involved observations of adult whitefly courtship behaviours to determine the impact of acetylated glyceride treatment, which is currently being developed as a repellent for adults, on their progeny. In addition, the effect of acetylated glyceride treatment on acoustic-based communication was evaluated, as this type of communication is known to play a pivotal role in the search for mating partners on host-plant leaves in adult whiteflies. Adults were able to land on grape tomato leaves a few days after treatment, when the residual repellency had dissipated. Almost no male courtship behaviour in terms of searching for sexually mature females was observed throughout the observation period (60 min) under conditions in which adults of both sexes remained on a treated leaf or those in which an adult of either sex remained on a non-treated leaf. By contrast, these behaviours accounted for 26.5% of the observation time under conditions in which both sexes remained on a non-treated leaf. In cross-tests performed for 4 days using one non-mated female and two non-mated males, the sex ratio (male/ female) of the newly emerged adults on treated leaves (2.4) was 63.6% lower than that of the non-treated controls (0.9). During courtship, acoustic signals produced by both sexes were exchanged rhythmically on non-treated leaves, whereas the signals on treated leaves were irregular. The frequency of the vibratory sound produced by males was 66-81% lower on the treated leaves than on the non-treated leaves. A large reduction in the acoustic signals produced by males on treated leaves caused a decrease in courting pair formation, leading to a significant reduction in the number of female progeny due to arrhenotokous parthenogenesis in virgin B. tabaci females.

“…After successive foliar treatments with 0.2% (v/v) acetylated glyceride 2 or 3 times at 7-day intervals, we observed a large reduction in whitefly adults, courting pairs, and nymph populations on eggplant leaves in a plastic greenhouse. 10) In the present study, we observed the effects of treatment with acetylated glyceride on the process of host selection behaviors and morphological characteristics of their labia and oviposition behaviors of B. tabaci adults. In addition, we evaluated the impact of the treatment on various developmental stages of B. tabaci in laboratory conditions.…”

The effectiveness of acetylated glyceride (acetic and fatty acid esters of glycerol) developed as an adult repellent was clarified by observing the host selection behavior of the sweet potato whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), on treated plant leaves. In a choice test between treated and untreated grape tomato leaves, it was observed that almost the same number of adults landed on the leaves, but the retention rates of adults settling under the leaves were 27% and 95%, respectively. Repellent behavior was induced within 5 sec of the adult's landing on the plant surface. The repellent led to a large reduction in the number of eggs laid on grape tomato leaves as compared to untreated leaves. However, no adulticidal activity by direct foliar treatment and no insecticidal activity against the progeny by contact treatment were found on cucumber leaves.

“…We recently found that acetylated glyceride (acetic and fatty acid esters of glycerol), used as a plasticizer for chewing gum base (food additive), has a highly repellent effect and a courtship disruption effect on Mediterranean and Middle East-Asia Minor 1 (MEAM1, formerly B-biotype) B. tabaci adults without causing phytotoxicity to target crops or toxicity to beneficial insects (Kashima et al, 2014).…”
