The immature stages of Phoracantha recurva Newman, 1842 and Phoracantha semipunctata Fabricius, 1775 (Coleoptera, Cerambycidae) and a key to larvae of these species

Abstract

The description of the last instar larva and pupa of Phoracantha recurva Newman, 1842 and the redescription of the immature stages of Phoracantha semipunctata Fabricius, 1775 showing new characters of possible diagnostic value are presented in this work. A key of identification of both species based on these characters is also given.

The immature stages of Paramallocera hirta kirby, 1818 (Coleoptera: Cerambycidae: Elaphidionini)

“…Table 1 Irregular rows of spinifor setae on segments I-VII I-VI spiniform setae on a C-shaped line. VII-VIII spiniform setae irregularly distributed the main larval and pupal characteristics of 3 other species of cerambycids that attack Eucalyptus in Uruguay (Morelli et al, 2002;Morelli et al, in press) with P. hirta.…”

Within-Tree Distribution and Survival of the Eucalyptus Longhorned Borer Phoracantha semipunctata (Coleoptera: Cerambycidae) in a Mediterranean-Type Ecosystem

“…For every 1-m section, the loose outer bark was removed to ensure all emergence holes made by emerged borers could be clearly located and were then counted. These holes were oval in shape and approximately 8 mm in diameter; with adult borers present in some of these holes were identified as P. semipunctata using taxonomic keys [14,18,46]. No other species of Cerambycidae were found.…”
