dc.description.abstractThe effect of four different temperatures (15, 20 25 and 30°C), on biological parameters of the Azorean population of Glyptapanteles militaris (Walsh) was studied, using Mythimna unipuncta (Haworth) as the host. Thirteen biological parameters of the were analyzed: percentage of hosts that died without producing parasitoids; percentage of larvae parasitized from which parasitoids emerged; percentage of hosts surviving to pupate after the parasitoid's sting; egg-larval development time; pupal period; total developmental time; adult longevity; total number of larvae per host; number of larval parasitoids that fail to emerge from each host; mean number of parasitoids that emerged from host larva but failed to spin a cocoon; mean number of cocoons per host; parasitoid sex-ratio; and finally emergence rate of adult parasitoid progeny. The percentage of hosts that died without producing parasitoids increased with increasing temperature. Developmental times significantly decreased with increasing temperature. The mean number of cocoons per host; mean number of parasitoids that emerged from each host larva but failed to spin a cocoon; and total number of larvae per host were higher when the temperature was lower. Parasitoid sex ratio and emergence rate of adult progeny were not affected by the temperatures tested.por
