Abstract
The red-necked longhorn beetle, Aromia bungii (Coleoptera: Cerambycidae), is a wood-boring pest of ornamental cherry trees in the Rosaceae family. This study evaluates the effectiveness of a preventive measure using fine-mesh netting in preventing A. bungii from oviposition on host cherry trees. Aromia bungii typically oviposits in cracks and crevices of host tree bark using its elongated ovipositor, leading to higher infestations on the lower trunk where there are abundant rough barks suitable for the beetle oviposition. Therefore, we assessed the effectiveness of netting with a gap that exceeded the reach of the A. bungii ovipositor from the tree surface. This evaluation involved laboratory experiments using cut branches and field experiments using lower trunks from standing trees. In the field, we determined the distribution of A. bungii body sizes and estimated the maximum ovipositor length based on their proportional relationship. This led to the establishment of a 10 mm gap for the test net, featuring a 0.4 mm mesh. Both laboratory and field experiments confirmed that the 0.4 mm mesh net with the specified gap effectively prevented A. bungii oviposition in netted areas. Field experiments also suggested a potential shift in oviposition sites from netted (lower) to un-netted (upper) areas in trees with nets, considering results from trees without nets. Although various measures, such as insecticide spraying, are necessary to safeguard areas without nets, our netting method can serve as a fundamental component of integrated pest management against A. bungii.
红颈长角蠹 Aromia bungii(鞘翅目:Cerambycidae)是蔷薇科观赏樱桃树的一种蛀木害虫。本研究评估了使用细网预防措施阻止 A. bungii 在寄主樱桃树上产卵的效果。Aromia bungii通常利用其细长的产卵器在寄主树皮的裂缝中产卵,导致树干下部的虫害较高,因为那里有大量适合甲虫产卵的粗糙树皮。因此,我们评估了间隙超过 A. bungii产卵器从树表面到达的距离的网具的效果。评估包括使用剪下的树枝进行的实验室实验和使用立木下部树干进行的现场实验。在野外,我们确定了 A. bungii 的体型分布,并根据它们的比例关系估算了最大产卵器长度。因此,我们为试验网设定了 10 毫米的间隙,网眼为 0.4 毫米。实验室和现场实验都证实,0.4 毫米网眼的指定间隙能有效防止 A. bungii 在网区产卵。现场实验还表明,考虑到没有网的树木的结果,有网树木的产卵地点可能会从有网区域(下部)转移到无网区域(上部)。尽管有必要采取各种措施(如喷洒杀虫剂)来保护无网区域,但我们的撒网方法可以作为虫害综合防治的一个基本组成部分。
期刊介绍:
Journal of Pest Science publishes high-quality papers on all aspects of pest science in agriculture, horticulture (including viticulture), forestry, urban pests, and stored products research, including health and safety issues.
Journal of Pest Science reports on advances in control of pests and animal vectors of diseases, the biology, ethology and ecology of pests and their antagonists, and the use of other beneficial organisms in pest control. The journal covers all noxious or damaging groups of animals, including arthropods, nematodes, molluscs, and vertebrates.
Journal of Pest Science devotes special attention to emerging and innovative pest control strategies, including the side effects of such approaches on non-target organisms, for example natural enemies and pollinators, and the implementation of these strategies in integrated pest management.
Journal of Pest Science also publishes papers on the management of agro- and forest ecosystems where this is relevant to pest control. Papers on important methodological developments relevant for pest control will be considered as well.
