Estudio de la biología del ácaro hindú de los cítricos Schizotetranychus hindustanicus (Hirst, 1924) (Acari: Tetranychidae), en tres tipos de alimentos.

Abstract

This study was carried out under laboratory conditions on three kinds of alimentary items, namely: orange, persian lime and lemon leaves. Populations were set in rearing sands divided into two sections with 70 individuals per treatment. Likewise, female population were separated into two groups (stationary and not stationary). Cycle length was similar in treatments used, viz. 30, 12 and 31, 10 days, resulting few generations a year. Biological characteristics like longevity, fecundity and fertility were not affected by the treatments. In fertilized and virgin populations on different alimentary substrata the highest number of eggs oviposited occurred during the first eight days. This number of eggs diminished progressively until the female’s death. Among the developmemtal stages of the species, eggs and adults lasted longest. This species had a low reproduction rate and large oviposition periods, showing a similar behavior on persian lime, orange and lemon plants.
