Jy. Honda et al., DEVELOPMENT, REPRODUCTION AND LONGEVITY OF ORIUS-MINUTUS AND ORIUS-SAUTERI (HETEROPTERA, ANTHOCORIDAE) WHEN REARED ON EPHESTIA-KUEHNIELLA EGGS, Applied Entomology and Zoology, 33(3), 1998, pp. 449-453
Developmental, reproductive, and adult longevity, rates of Orius minut
us (L) and Orius sauteri (Poppius) were studied in the laboratory usin
g eggs of Ephestia kuehniella Zeller as prey. Immature development for
both species took approximately 12 days and did not differ significan
tly between the sexes. Total fecundity rates were significantly higher
for O. minutus (105.36) than O. sauteri (68.40) as were male longevit
y rates (18.11 days vs. 11.50 days) and female longevity rates for bot
h virgin (16.73 days vs. 24.75 days) and ovipositing (13.90 days vs. 1
9.69 days) individuals. However, O. minutus suffered higher mortality
rates in the laboratory, thus calculated intrinsic rates of natural in
crease were for O. minutus (r(m)=0.137) and O. sauteri (r(m)=0.132) we
re similar.
