Egg bursters in the Chrysomelidae, with a review of their occurrence in the Chrysomeloidea and Curculionoidea (Coleoptera)

Abstract

The literature on the occurrence of egg bursters in first instar larvae of the Chrysomeloidea and Curculionoidea is reviewed. The egg bursters and chaetotaxy of the tubercles on which they occur are described for the larvae of 221 chrysomelid species, representing fifteen of the nineteen subfamilies. The value of these as subfamily, generic and specific characters is discussed and also their use as indicators of the phylogenetic relationships among these different groups. Possible explanations are proposed for the absence of egg bursters in certain chrysomelid subfamilies.

Natural history of Javeta pallida Baly, 1858 on Phoenix palms in India (Chrysomelidae, Cassidinae, Coelaenomenoderini)

“…This is interesting as most Cassidinae have five instars and a few particular species have up to nine instars (Chaboo 2007). Coelaenomenoderine instar 1 appears to lack egg bursters (Cox 1988, 1994). …”

“…The limited data indicates Arecaceae, Cyperaceae, Pandanales and Zingiberales as host plants (Staines 2004, 2012b). Juvenile stages (larva or pupa) are known for just two species—Coelaenomenodera (Coelaenomenodera) elaeidis Maulik (Maulik 1920; Cox 1988, 1994) and Cyperispa hyloytri Gressitt (Cox 1996). …”

2.4. Cerambycidae Latreille, 1802

“…The prevalent chromosome number is 2n = 20 (the presumed ancestral number of Polyphaga) or close to that value, although numbers from 10 to 36 have been recorded (Smith & Virkki 1978;Petitpierre 1987;Roz . Parthe nogenesis is rare (Cox 1996); thelytoky has been documented in Kurarua rhopalophoroides Hayashi (Cerambyc inae) in Japan (Goh 1977) and undoubt edly occurs in femaleonly populations of Cortodera (Lepturinae) from the Caucasus and one species of Neotropical Acanthocinini (Lamiinae) reared by the hundreds (A. Males typi cally show the Xy p type of sex chromosomes (a small y chromosome forming a "parachute" pat tern with chromosome X at meiotic metaphase I) or slight modifications (such as duplicate X or one or two supplementary chromosomes).…”

Together with 30 years of Symposia on Chrysomelidae! Memories and personal reflections on what we know more about leaf beetles
