Evaluation of the ambrosia beetles traps on Pterocarpus indicus in Indonesia

Abstract

Abstract. Tarno H, Setiawan Y, Rahardjo BT, Wang J. 2021. Evaluation of the ambrosia beetles traps on Pterocarpus indicus in Indonesia. Biodiversitas 22: 1332-1339. Angsana, Pterocarpus indicus Willd., is a native tree of Southeast Asia. This tree is commonly planted in large numbers as an ornamental or shade plant along the roads, in parks, and in residential areas in Malang and Batu Cities of Indonesia. Ambrosia beetles Euplatypus parallelus (F.) and Treptoplatypus micrurus (Schedl.) have been reported to attack P. indicus trees in Malang and Batu Cities. Therefore, effective traps are required for early detection and monitoring of the spread of ambrosia beetles. This research aimed to evaluate the effectiveness of different traps and to investigate the diversity of ambrosia beetles on P. indicus trees in Malang and Batu Cities. This research was conducted along the roads in Malang and Batu Cities using four types of traps: funnel trap, window flight trap, bottle trap, and yellow sticky trap. Eleven ambrosia beetle species were collected in this research. The most abundant species were E. parallelus and Cryphalus laticollis (Browne). The funnel trap was the most effective for capturing ambrosia beetles, whereas the bottle trap was the least effective trap. The funnel trap captured more E. parallelus and C. laticollis individuals than other traps. The ambrosia beetles captured using different traps were categorized as having low diversity. The ambrosia beetles collected from Malang and Batu Cities were categorized as having moderate diversity.

Efficacy of different lures for Phloeosinus aubei and other native and exotic bark and ambrosia beetles

“…Flight intercept traps, including those made from PET bottles (Pajek et al, 2020;Sanguansub et al, 2020;Steininger et al, 2015;Tarno et al, 2021) can effectively be used for monitoring P. aubei by baiting them with a juniper or thuja branch (c. 10 cm long and c. 3 cm thick) deployed with ethanol. Our study demonstrates that even at low population densities, the detection of this bark beetle is possible.…”

Incidence and damage of the ambrosia beetle on cocoa plants in East Luwu District, South Sulawesi, Indonesia

“…The population of the ambrosia beetle detected to attack teak plants in Southeast Sulawesi (Maros) included Xyleborus affinis (47.17%), Xylosandrus crassiusculus (27.64%), and Hypothenemus sp. (12.33%) (Tarno et al 2022). Furthermore, the first attack of this pest on cocoa plants occurred in East Luwu District, South Sulawesi Province, in Wotu Sub-district.…”

“…One such threat is the ambrosia beetle (Gregoire et al 2014) which has been reported to attack cocoa plants in several countries such as India (Thube et al 2022), Brazil (Macedo-reis et al 2016, and Peru (Delgado and Couturier 2017). This beetle was reported to also attack various plant species such as Persea americana (Carrillo et al 2012), Tectona grandis (Tarno et al 2022), Pinus spp. (Ploetz et al 2013), Pterocarpus indicus (Tarno et al 2021) and Areca catechu L. (Thube et al 2018), resulting in a significant decrease in population and production of the main commodity.…”
