The effects of temperature on the development of the moth Acrobasis advenella (Zinck.) in the laboratory
Abstract
To clarify the biological characteristics of A. advenella and to establish a forecasting for the pest, the growth duration of individual stages and the developmental threshold temperature for A. advenella have been investigated. For the same developmental stages, the development duration significantly decreased as the temperature was increased from 22 to 26°C. At the temperature of 10°C females do not lay eggs, and the reared caterpillars and pupae died. The duration of the embryonic developmental stage in the tested ranges of temperatures was between 9.3 (26°C) to 25 days (14°C). The rate of 1st stage larvae development at the temperature of 26°C was the shortest – 10 days. The longest development of larvae was observed at the temperature of 14°C – 17 days. At the temperature of 26°C the development of the larvae of the 2nd instar lasted the shortest – 6 days. The longest developmental stage of larvae was observed at the temperature of 14°C – 8.9 days. Laboratory rearing showed that older larvae – of the 3rd and 4th stages developed the shortest at the temperature of 26°C (3.3 and 12 days, respectively). The longest developmental stage of larvae was observed at the 14°C and it was 11.5 days for the 3rd and 32 days for the 4th instar. The duration of the pupae development in the tested ranges of temperatures ranged between 15 (26°C) to 36.5 days (14°C). This information may be used to establish the dates of this pest control.
