HOMALODISCA COAGULATA (HEMIPTERA: CICADELLIDAE) EMBRYONIC DEVELOPMENT AT CONSTANT TEMPERATURES

HOMALODISCA COAGULATA (HEMIPTERA: CICADELLIDAE) EMBRYONIC DEVELOPMENT AT CONSTANT TEMPERATURES

Development rate of Homalodisca coagulata (Say) was linearly related to temperature from 16.7 to ca. 30 degree C. It is estimated that H. coagulata requires 113.8 degree-days from oviposition to egg hatch, with a minimum developmental threshold of 11.9 degree C. At higher temperatures, hatch rate wa...

Zusammenfassung:Development rate of Homalodisca coagulata (Say) was linearly related to temperature from 16.7 to ca. 30 degree C. It is estimated that H. coagulata requires 113.8 degree-days from oviposition to egg hatch, with a minimum developmental threshold of 11.9 degree C. At higher temperatures, hatch rate was significantly reduced, especially at 35 degree C.
