Records of two citrus pest whiteflies in Japan with special reference to their mating sounds (Homoptera: Aleyrodidae).

Abstract

A serious citrus pest, the ash whitefly, Siphoninus phillyreae Haliday, was first recorded in Honshu and Kyushu, Japan. The favored host plant is pomegranate (Punica granatum L.) from early summer to autumn. The adults migrate to a hedge plant (Photinia glabra (Thumb.) Maxim.) or rarely to a citrus plant (Citrus natsudaidai Hayata) before pomegranates shed their leaves in winter. Another citrus pest, the woolly whitefly, Aleurothrixus floccosus Maskell, was found from Nansei Islands to north of Tokunoshima Is., Japan. The distribution of these two pests and diagnostic features were detailed. Substrate-borne vibratory sounds produced during mating were elucidated, including new findings of male and female communication by reciprocal sound signals. It is suggested that the species-specific bioacoustic signals preserve useful information for the whitefly biosystematics of economic importance.

The presence of six cryptic species of the whitefly Bemisia tabaci complex in China as revealed by crossing experiments

“…Cuticular hydrocarbons (CHCs) secreted from a variety of glands and accumulated on the external surface of the exoskeleton have been shown to act as contact signals for species, kin and mate recognition in numerous species of insects (Howard, 1993; Howard & Blomquist, 2005; Dani, 2006; South et al , 2008; De Barro et al , 2011). Whitefly males and females have also been shown to exchange reciprocal sounds during mate finding and courtship leading to copulation (Kanmiya, 1996; Kanmiya & Sonobe, 2002). It seems likely that CHCs, acoustic signals, or possibly both may play a role in mate recognition in B. tabaci .…”

Crossing experiments and behavioral observations reveal reproductive incompatibility among three putative species of the whitefly Bemisia tabaci

“…Cuticular hydrocarbons (CHCs) secreted from a variety of glands and accumulated on the external surface of the exoskeleton have been shown to act as contact signals for species, kin and mate recognition in numerous species of insects (Howard, 1993; Howard & Blomquist, 2005; Dani, 2006; South et al , 2008). Whitefly males and females have also been shown to exchange reciprocal sounds during mate‐finding and courtship leading to copulation (Kanmiya, 1996; Kanmiya & Sonobe, 2002). Recent work on Laupala crickets demonstrated both interspecific and sex differences in CHC composition, and suggested that acoustic signals were used for long‐range mate attraction while CHCs functioned in close‐range species discrimination (Mullen et al , 2007).…”
