Another very small Calandrini, 7-8 mm, is also very common on the fronds cut, attracted by fresh exudates, Diocalandra frumenti (F.). This insect is harmless, the larvae feeding only in the upper part of the tissues of the petiolar leaves, recently pruned. But now two bigger species, 12 and 14 mm, are found very numerous in oil palm plantation along with D. frumenti, Rhaboscelus maculata Gyll. already recorded in Malaysia and Rhabdoscelus obscurus Boisd. These two weevils have never been mentionned in Indonesia and the latter one is able to damage the bunches. R.maculata is living only as D. frumenti in the petiolar bases freshly cut, but R. obscurus can be found also in the living tissues of bunches boring inside the peduncule, the rachis or even the spiklets and the fruits. Damages in Sumatra in the first years of production are very variable according to the vegetal material and the cultural practices. Material with slow growth with often wounds during castration is more affected. The white grubs boring the peduncule before maturation of the fruits can provoke a decay of the upper part of the bunch, similar to a lack of pollination. Inside the rachis, after the feeding of the larvae, a large black longitudinal necrosis occurs reducing the development of the spiklets, and favouring the spread of bacteria in the soft tissues and fruits. The percentage of bunches affected can reached 21.4% on some crossings, but in average is only 5.1% on commercial fields, when this weevil is present. On mature palms damages are also present with the feeding cavity inside the rachis causing a frequent fracture of the bunch. The biology of this new pest has been studied, description of the adults and larvae are given. The life cycle is completed in 94 days. Until now Rhabdoscelus obscurus was known in the Pacific Islands, Papua New Guinea and Queensland. In Indonesia this pest has been only recorded in Irian Jaya and Moluccas, mostly on sugar cane, banana, coconuts and wild palms. Now this species has spread to the western part of the archipelago, and is present and well established in Sumatra oil palm plantations. Damages although still limited have to be taken into consideration and monitored.

In a field experiment at eight different locations (Dededo, Tumon, Yigo, Hagåtña, Mangilao, Yona, Agat and Malesso), plastic bucket traps baited with the lure of the Australian R. obscurus population in combination with a food volatile compound (ethyl acetate) and cut sugarcane captured significantly more weevils (total of 348) than traps baited with pheromone lure of the Hawaiian R. obscurus population in combination with food volatile and cut sugarcane which caught a total of 128 weevils. Traps baited with lure containing only the food volatile and cut sugarcane or only cut sugarcane captured significantly fewer weevils (total of 36 and 30, respectively) than those baited with pheromone compounds. Data from trap catches indicate that the Guam population of R. obscurus responded significantly more to the pheromone lure of the Australian population than to pheromone lure of the Hawaiian population indicating that the Guam R. obscurus population is related more closely to the Australian population. Trap catches at the Tumon and Dededo locations were greater than those in Yigo, Yona, Mangilao, Hagåtña, Agat, and Malesso. Rainfall had a low correlation with trap catches at all locations except at Yigo where it positively correlated to the Australian population lure treatment. Semiochemical based trapping in weevil management has potential either in mass trapping or as part of an IPM program. A future line of work is also proposed for the control of weevil borers based on these initial results.10aDryophthoridae10aRhabdoscelus10aRhabdoscelus obscurus1 aMUNIAPPAN, R.1 aBAMBA, J.1 aCRUZ, J.1 aREDDY, G., V.

In recent years the cultivation of ornamental palms (Arecaceae) has increased markedly in northern Queensland. Consequently, several insects have become important pests, particularly Rhabdoscelus obscurus (Boisduval), the cane weevil borer. The larvae of this beetle feed on various species of palms, making the plants unsaleable. Death or lodging of the trees may also result. This paper documents its pest status, derived from information in the literature and from consultation with lcoal growers.
