KeywordsAcari Ixodidae Boophilus microplus egg laying environmental factors
Oviposition of Boophilus microplus (Canestrini) was studied under varying conditions of temperature, light and humidity. Eggs were laid throughout the temperature range of 55-102°F., with the optimum temperature between 80-850F. A temperature of ro5°F. inhibited oviposition completely but was not lethal to the adult; a temperature of ro7°F. for 24 hours was lethal. Engorged ticks survived for over 90 days at a t emperature range of 40-6o°F. (mean 50°F.) but oviposition was limited and theeggsnotviable. Relative humidities of less than 30 % and immersion in water for over 24 hours severely inhibited oviposition; light had little influence on egg-laying.
