Susceptibility of three predatory arthropods namely Asian lady beetle, Harmonia axyridis (Pallas), lynx spider, Lycosa pseudoannulata (Boescriberg and Strand), and wolf spider, Oxyopes javanus (Thorell) to four commonly used biorational molecules viz. buprofezin, spinosad, emamectin benzoate and abamectin were determined in a brinjal ecosystem. Biorational pesticides were applied singly and in some selected combinations and their toxicity on the predators was recorded up to three sprayings in a confined habitat. Buprofezin caused no significant mortality of predators (2.87%, 0.32%, 0.96% mean mortality per spray of Asian lady beetle, lynx spider, and wolf spider respectively) and was found most compatible among the biorational molecules. However, other three tested molecules were found highly toxic for all predatory natural enemies when applied singly or in combination with buprofezin. Spinosad was most toxic for Asian lady beetles (21.84% mean mortality per spray) and lynx spiders (15.32 % mean mortality per spray) whereas abamectin (17.78% mean mortality per spray) for wolf spiders. It was observed that the number of spraying was very crucial and had a proportionate relationship with the mortality percentage of predators. Based on this study it is suggested that buprofezin could be considered to incorporate safely in the IPM program for brinjal pest management.J. Bangladesh Agril. Univ. 15(2): 234-238, December 2017

Field tests were conducted to determine if, at the conclusion of their autumn migratory flight, Harmonia axyridis (Pallas) are attracted to and preferentially alight on targets covered with the printed images of lady beetles. There was no significant difference in the number of beetles that landed on targets bearing depictions of coccinellids compared with the number that landed on blank, white controls. Results suggest that commercial traps that rely on images of lady beetles to attract incoming coccinellids are of little practical value.

Abstract The multicoloured Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae), has become a pest in North American vineyards during harvest due to its adverse effects on wine quality. This study evaluated alternative products that may be suitable for use in vineyards as repellents to the beetle. Products were screened as repellent for multicoloured Asian lady beetle in short-term laboratory trials. Thirteen products significantly reduced the number of beetles on grapes, Vitis vinifera (Vitaceae). Products that showed a 50% or greater repellency were evaluated for residual repellency 24, 48, and 72 hours after application. In these trials, pine oil was highly repellent at each testing period, whereas the repellency of most other products decreased over time. Eight repellent compounds were evaluated in field trials in commercial vineyards that had high multicoloured Asian lady beetle populations. The number of beetles on vines was counted 2–6 and 24–28 hours after application. In the field, the most effective repellents overall were Biobenton and Buran, which reduced the number of multicoloured Asian lady beetles by 39 and 34%, respectively. The discovery of new repellents of multicoloured Asian lady beetle provides an opportunity to improve management of the pest in vineyards and to reduce risk of wine taint without using broad-spectrum insecticides.

As one component of an Integrated Pest Management program for Midwestern wine grapes, we examined the efficacy of several insecticides on adults of the multicolored Asian lady beetle, Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae). For field trials, percentages of clusters with at least one H. axyridis were recorded for each plot before treatment and on the day of harvest. We also examined the efficacy of insecticides under laboratory conditions via two routes of exposure, topical application and insecticide residues. In the 2004 field trials, the percentage of clusters infested with H. axyridis adults at harvest was statistically lower in plots treated with bifenthrin applied 7 days before harvest (DBH), carbaryl 10 DBH, and in plots covered with floating row cover compared to the untreated plots. In 2005, the percentage of clusters infested with H. axyridis adults at harvest in plots treated with zeta-cypermethrin 7 DBH, bifenthrin 22 and 7 DBH, and imidacloprid 1 DBH was statistically lower than beetle infestation in the untreated plots. In the laboratory, bifenthrin, carbaryl, and thiamethoxam were lethal to H. axyridis adults 7 days after treatment. Based on the efficacy results, labeled insecticides, pre-harvest intervals, and the late-season influx of H. axyridis infestations, chemical control is currently limited to carbaryl, malathion, and/or imidacloprid.

Over Time

Several studies were conducted to determine the cues used by the lady beetle Harmonia axyridis (Pallas) when orienting to aggregation sites in autumn: (1) artificial shelters modeled after those commercially available in mail order catalogues were baited with live adults and hung on the outside of buildings known from past years to be aggregation sites, (2) differential arrival of the two sexes at overwintering sites was examined by collecting and sexing the beetles alighting on buildings at two points in time during the aggregation period, and (3) the distribution of overwintering H. axyridis among beehives was determined in ten apiaries. Results indicate no preference for the artificial shelters and no orientation to the conspecifics within them. Sex ratios of beetles arriving at aggregation sites were consistent over time in two of the three sites examined. During winter, adult H. axyridis were non-randomly distributed among physically similar beehives. We conclude that there is little evidence for volatile aggregation pheromones and suggest that the chemical cues that mediate the final stages of aggregation behavior in H. axyridis may be based on contact chemoreception with conspecifics or the feces and residues that persist in aggregation sites from previous years.
