Preimaginal development of Cephalcia lariciphila during an outbreak in the Czech Republic

Popis výsledku v původním jazyce

An outbreak of Cephalcia lariciphila (Wachtl) (Hymenoptera Pamphiliidae) occurred in a mature spruce-larch forests near the village of Větrný Jeníkov (15°30'E, 49°28'N) between 2001 and 2004, when there were from 122.2 ? 118.8 (mean ? SD) to 276.6 ? 141.8 prepupae per m2 of soil. The prepupae density declined to 23.0 ? 21.2/m2 by the spring of 2006 and continued to decline to undetectable levels in 2007-2009. From 2002-2006, the percentage of larvae that were still eonymphs in the autumn and spring ranged from 18 to 50%, and the percentage of prepupae parasitized by the wasps Notopygus bicarinatus Teunissen and Ctenopelma lucifer (Gravenhorst) (Hymenoptera Ichneumonidae) ranged from 4.5 to 10.5%. The number of eggs detected was similar in upper, middle, and lower parts of the tree crown. The average number of eggs per twig (length ca. 30 cm) was always < 1. In the forest, the first larvae were observed on 15 May and the last on 10 June. In the laboratory at 20 °C, females laid 32.3 ? 7
