Egg brochosomes of Proconiini (Hemiptera: Cicadellidae, Cicadellinae) species associated with cultivation of grapevines
Scientia Agricola 65 (2), 209-213
Abstract: Brochosomes production is considered a feature of Cicadellidae, and may represent an outstanding innovation which has played an important role in the development and diversification of this insect group. The objective of this study was to identify the species of Proconiini that produced egg brochosomes associated with grapevines in the Serra Gaúcha region of Brazil. Egg brochosome characteristics and an identification key are also discussed. The specimens were collected using yellow sticky cards in four vineyards (Vitis vinifera L.) from October 2004 to May 2006. Eight species capable of producing egg brochosomes were identified: Acrogonia citrina Marucci and Cavichioli; Homalodisca ignorata Melichar; Molomea consolida Schröder; Molomea lineiceps Young; Molomea personata (Signoret); Oncometopia facialis (Signoret); Oncometopia fusca Melichar; and Tapajosa rubromarginata (Signoret). Egg brochosomes are useful structures to identify Proconiini species in vine.
