| abstract | Guava mite, Aculops guajavae (Acari: Eriophyidae) is delineated and illustrated as a new species in Egyptian fauna. It had been found in Behera province in spring and summer seasons totally on the lower aspect of succulent terminal guava leaves (Psidium guajava L.), preferring the lower leaf surfaces. A. guajavae successfully developed from egg to adult stage once reared on succulent guava leaves at totally different temperatures between 15 - 30°C and 75% R.H. The impact of temperatures on the biological aspects was demonstrated. At 7°C the activity of the guava mite was ceased, whereas at 36°C the new virgin adults died. Males started depositing spermatophores inside 24 hours when changing into adults, with general average 12 a day. Female longevity at 15°C averaged 22.91 days, about 1.48 times as long as at 30°C. Oviposition rate was highest at 30°C (43.18 eggs/♀). Population of guava mite increased 19.22 times in an exceedingly generation of 14.67 days at 30°C and 75% R.H. |
