(1) C. g. galbinifrons BOURRET, 1939, distributed in North Vietnam (Tonkin) and adjacent southern China, is characterized by its flat and elongated shell and a mainly or entirely black plastron. The carapace bears a wide, anteriorly forked dark brown median band and lacks a solid dark lateral band. The soft parts are sometimes intensely reddish coloured. (2) C. g. bourreti OBST & REIMANN, 1994, occurs in Central Vietnam (Annam, except the southernmost part), and the neighbouring regions of Laos and Cambodia. It is distinguished from the nominotypical subspecies by its more domed, rounder shell, a plastral pattern consisting of black …

Precocene Ii Modifies Maternal Responsiveness In The Burrower Bug, Sehirus Cinctus (Heteroptera)., Scott Kight Dec 1997

Precocene Ii Modifies Maternal Responsiveness In The Burrower Bug, Sehirus Cinctus (Heteroptera)., Scott Kight

Scott Kight

The anti‐Juvenile Hormone agent precocene II was used to investigate the relationship of corpora allata activity to subsocial behaviour in a burrower bug Sehirus cinctus Palisot (Heteroptera: Cydnidae). Egg‐brooding females treated with a range of dosages of precocene II exhibited reliably depressed maternal defensive behaviour when treated with at least 70 μg of precocene II, but attraction to eggs was only depressed at higher dosages. This effect was not due to precocene II toxicity, as demonstrated by the prevention of depression effects through simultaneous treatments of precocene II and the Juvenile Hormone analogue methoprene. Methoprene, however, failed to reinstate maternal …
