Biological Aspects of Diaphurina Citri (Hemiptera: Lividae) Reared In Uncontrolled Greenhouse Conditions

Abstract

This study was aimed at determining biological aspects of D. citri reared in a greenhouse under uncontrolled conditions during summer and winter seasons in Tecomán, Colima, México. The life cycle of D. citri lasted 52.78 ± 5.52 days in the summer and 68.7 ± 5.43 in the winter. The fecundity (m) and the net reproductive rate (R₀) reached values greater than unity, showing that the population was growing. The growth rate of the population in winter was higher (16.1) than in summer The Logrank (Xcal 39,1X20.05 (2-1)=3,8415) test showed a difference between life Liberated Theme (4.15.05 1,96) test indicated that this difference occurred in eggs and early nymph instars (I-II). A female of D. citri oviposited 541 and 786 eggs in summer and winter, respectively. However, a "t" test showed that there was no difference between the oviposition of D. citri during the summer and winter seasons (F1.59; P>0.1512). Winter was the most suitable season for producing the greatest amount of nymphs.
