Effect of temperature on the development and viability of Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae) parasitizing Spartocera dentiventris (Berg) (Hemiptera: Coreidae) eggs O efeito da temperatura no desenvolvimento e na viabilidade de Gryon gallardoi (Brethes) (hym.: scelionidae) parasitando ovos de Spartocera dentiventris (Berg) (Hem.: coreidae)

The development and viability of Gryon gallardoi (Brethes) (Hym.: Scelionidae) in Spartocera dentiventris (Berg) (Hem.: Coreidae) eggs were studied under four temperatures: 15, 20, 25, and 30 ± 1ºC, with a 12-h photophase. No parasitoid developed at 15ºC. Otherwise, viability reached 98.8...
