“…Both the maxillary and labial palps direct food to the mouth and hold it while the mandibles chew the food. The distal ends of these palps are flattened and have shovel-like setae (Moon et al 2008).…”

We studied the biology of the ambrosia beetle Platypus quercivorus in the logs of five tree species to determine: (1) the relationship between the amount of frass produced by beetles and tunnel length, (2) the relationship between frass shape and the morphological characteristics of P. quercivorus mouthparts, and (3) the suitability of five tree species for P. quercivorus reproduction. Five logs each from healthy Quercus crispula, Q. serrata, Castanea crenata, Sorbus japonica, and Cryptomeria japonica trees were used in this experiment. The results showed that there was a linear relationship between the amount of frass and tunnel length. Whenever powdery frass was produced, larvae were found in the gallery in the log, while fibrous frass was present only in galleries that contained just adults. The mouthparts of adults were completely sclerotized, which likely accounts for the fibrous frass production. Host preference of P. quercivorus was examined at two stages using five tree species. The first stage is digging initiation, which concerns male preference for digging a tunnel. More holes were made by males on S. japonica and Q. serrata logs, while fewer holes were made on C. japonica logs. The second stage is characterized by female orientation, mating, and progeny development. Platypus quercivorus could complete its lifecycle only in the two Quercus spp.

“…Ambrosia beetles including Euplatypus parallelus, P. quercivorus, and P. koryoensis commonly produce frass (Moon et al, 2008b;Tarno et al, 2011;Tarno et al, 2014). Ambrosia beetle makes galleries directly into the sap and heartwood of the tree using its functional mouthpart (Moon et al, 2008b;Tarno et al, 2011). The frass is made by adult has its typical fibrous shape and called fibrous frass (Moon et al, 2008b;Tarno et al, 2011).…”

NEW RECORD OF THE AMBROSIA BEETLE, Treptoplatypus micrurus Schedl. ATTACK ON SONOKEMBANG (Pterocarpus indicus Willd.) IN BATU, INDONESIA

2015

Sonokembang (Pterocarpus indicus Willd.) is commonly planted as an ornamental tree in Batu city, East Java. In 2012 and 2013, there were some dying trees of sonokembang along the road of Batu city, and there were some indications that the signs and symptoms might be related to the ambrosia beetle samples from Batu. To clarify the precise condition, identification of beetle samples was needed in this research. Based on survey and sample collections conducted in Batu from the early July 2013 to the end of March 2014, characteristic of damage on trees was observed together with the presence of beetle collected. Identification was based on morphological characters such as posterior elytral declivities and body size of male, and mycangia on female`s pronotum. Based on the morphological characters, there were some special characters which described such as 1) the body size of female adult was bigger than male adult, 2) elytral declivities on male adult was unique, and 3) there was mycangia on pronotum of female adults. Morphological characters showed that the ambrosia beetle attacked on sonokembang belonged to Treptoplatypus micrurus Schedl. This ambrosia beetle species seems to be the responsible agent that caused dying trees of sonokembang.

“…A common peculiarity of these species is two subtypes of SB at the apical of the last segment of maxillary and labial palps. They are reported in Pa. fuscipes (Liu et al 2008), Platypus koryoensis (Moon et al 2008), Ips acuminatus (Moon et al 2014) and Si. zeamais (Chen et al 2016).…”

Most species of Staphylinidae are predators in an agroecosystem. They acquire prey information from their environment through receptors. In this study, the sensilla on maxillary and labial palps of Philonthus kailiensis, Philonthus lewisius and Quedius robustus were examined with scanning electron microscopy to identify and analyse the external morphology and distribution of the sensilla to enhance our knowledge of the sensilla of Staphylinidae and provide a rationale of taxonomical studies on the two genus. Results showed that the sensilla are classified into six types: Böhm bristles, sensilla chaetica, sensilla furcate, sensilla coeloconica, sensilla placodea and sensilla basiconica. No sexual dimorphism exists among the three species. The relationships and functions of sensilla on maxillary and labial palps were also speculated. There may be a certain correlation between the sensilla on maxillary and labial palps of the staphylinid and its habitat.
