Abstract
Pagiocerus frontalis produced offspring on maize between 13°C and 30°C. Below and above these temperatures development was not completed. The optimum developmental temperature was 25°C.P. frontalis was able to produce F1 between 20% and 75% r.h. though the mortality at lower rel. humidities was high.
Zusammenfassung
Laboruntersuchung zur Feststellung der unteren Grenze der relativen Feuchte und der unteren und oberen Grenztemperatur für eine Entwicklung vonPagiocerus frontalis (Fab.) (Col., Scolytidae).
Im Temperaturbereich zwischen 13°C und 30°C konnte eine F1-Generation vonPagiocerus frontalis festgestellt werden. Die beste Temperatur für die Entwicklung lag bei 25°C.P. frontalis war in der Lage, im Bereich von 20–75% rel. Feuchte Nachkommen hervorzubringen, wobei die Mortalität bei geringer Luftfeuchte sehr hoch war.
