| Summary: | 碩士 === 國立中興大學 === 昆蟲學系 === 81 === Oligonychus coffeae (Nietner) was reared with the leaves of
Camellia sinensis var. TTES-12 at 15, 20, 25, and 30℃ constant
temperatures at 75?% RH and 13L:11D in the growth chambers.
The durations of developmental stages were decreased with
rearing temperature increase. The mortality of developmental
stages were higest at 15℃. Low developmental threshold and
thermal constant for female to develop and to moult into adult
were 12.57℃ and 143.82 degree-day,respectively, while those
for male are 12.55℃ and 142.15 degree-day, respectively. At
25℃ female densities and sizes of leaf disc significantly
influence the daily egg reproductivity, while sizes had greater
influence than the densities. Positive effects of female
densities to its oviposition periods were observed, while
negative relation was found with its female fecundities. From
influences of the female densities and sizes of leaf disc on
female reproductivity and living cohorts of mites in the
rearing arena, the maximum mite load of a unit (cm) leaf disc
was estimated as 130 mite-day with daily reproductive rate of
1.9 eggs/♀/day.
