Die Raupen durchleben vier Stadien bis zur Verpuppung, welche nach 6 bis 30 Tagen eintritt. In Nordamerika musste man beispielsweise auf Grund von Resistenzen gegen Permethrin und Methomyl andere Wege zur Bekämpfung finden. The average incubation period was 2.2 ± 0.65 days. Sie sind nur mäßige Flieger und fliegen hüpfend meist nur kurze Distanzen. The first two stages are small and feed by mining the leaf; later, when they are larger they burrow through the leaf. Die Raupen sind anfällig auf Regen, durchschnittlich 56 % ertrinken daran, wobei starker Regen und niedrige Temperaturen höhere Ausfälle verursachen. English: Please report references to olei@despammed.com. However, it is highly dispersiv… Since temperature is the major abiotic factor influencing insect development and thermal requirements may vary among insect populations, it is important to know the effect of temperature on development and survival of a subtropical strain of P. xylostella. Die Kohlschabe ist einer der wichtigsten Schädlinge an Kreuzblütengewächsen, im Speziellen an Kohl. It is an important, occasional pest of canola in North Dakota.

Development and Reproductive Rate of the Diamondback Moth Plutella xylostella from Thailand. Symptoms & Life Cycle. Larvae initially feed as leafminers but soon emerge to feed on undersides of leaves. In both years in the spring, some of the first eggs were found before adults were caught in the traps. Die nachtaktiven Falter findet man meistens an oder in der Nähe der Raupennahrungspflanzen. Vor allem eine Kombination von verschiedenen Bekämpfungsmethoden ist erforderlich, um die Resistenz gegen Insektizide zu minimieren. Plutella xylostella (L.)
