Close range sound communications of the oak platypodid beetle Platypus quercivorus (Murayama) (Coleoptera: Platypodidae).

Abstract

The oak platypodid beetle, Platypus quercivorus, stridulates both during premating behavior and when stressed, as well as spontaneously. When a female was put onto the bark surface of a male-infested log, she began to walk and produce an "approaching chirp," searching for a gallery entrance. When finding one, she entered it and tried to pull a male out. If the male's abdomen became visible, she appeared to push her frons against his elytral declivity and made a "premating buzz" that lasted about 5-10 s. During this buzzing, the male backed out of the gallery in order to allow her in. Females that had been silenced via surgery did not evoke this reaction; thus, males apparently identified females by their buzzing sound. The male then followed the female into the gallery, and produced an "in-gallery chirp" with his posterior abdomen visible. After a while, both sexes backed out of the hole and copulated at the entrance. Both sexes produced "stress chirps" when confined inside a cotton ball, and "spontaneous chirps" when walking alone on the surface of an oak bark piece.

External microstructure of the ambrosia beetle Platypus koryoensis (Coleoptera: Curculionidae: Platypodinae)

“…In P. koryoensis , the antennae are very short and clubbed, and a lot of sensory hairs are compactly arranged on the surface of the last antennal segment. It has been reported that the antennae may be used in some families during mating, or among a few beetles for defense (Ohya & Kinuura 2001;Kobayashi & Ueda 2002). 2003), they are often similar within any given family (Romoser & Stoffolano 1998).…”

“…The antenna is a sensory organ that gathers information about the feel, sound, taste, smell, temperature and humidity of the beetle's environment (Ohya & Kinuura 2001). In P. koryoensis , the antennae are very short and clubbed, and a lot of sensory hairs are compactly arranged on the surface of the last antennal segment.…”

“…A similar pattern of antennal modification is commonly found among hardwood borers -ambrosia and bark beetles. It has been reported that the antennae may be used in some families during mating, or among a few beetles for defense (Ohya & Kinuura 2001;Kobayashi & Ueda 2002). In some cases, males and females of the same species have different antennal forms (Chapman 1982).…”

“…Although sound communication is important as a cue for the mating behaviour of the beetles, 4) field experiments have indicated that chemical communication by using an aggregation pheromone was responsible for the mass attack on oaks by the beetles.…”
