dominica (F.) (Coleoptera: Bostrichidae) on Milled Rice]]>AstutiL.P. MudjionoG. RasminahS. RahardjoB.T. 22013102One of the most important pest storage on milled rice is Rhyzopertha dominica
(Coleoptera: Bostrichidae). Despite of both quantity and quality of food, temperature
and relative humidity in the warehouse are important factors that affect the
development and growth population of R. dominica. The effect of temperature
and humidity on the population growth of R. dominica (F.) on milled rice
was studied in a laboratory experiment. The treatment consisted of eight temperature
levels (20, 25, 30, 32, 34, 36, 38 and 40°C) and three levels of relative
humidities (60, 70 and 80%). The result showed that at all levels of relative
humidity tested, R. dominica did not survive at 40°C, whereas at
38°C some R. dominica produced eggs but none of them hatched. With
the temperature-dependent equation it was found that the optimum temperature
to produce egg number, larvae number and adult number were 35.05, 33.59 and
33.27°C, respectively. At those optimum temperature, the maximum predicted
of egg number, larvae number and adult number occurred at 80% relative humidity,
i.e., 209.33 eggs, 128.64 larvae and 38.75 adult insect. The study also showed
that R. dominica had the shortest (25.00 days) developmental time at
36°C with 80% relative humidity. The longest developmental time (106.33
days) was observed at 20°C with 60% relative humidity. At all relative humidity
levels tested, the growth index of R. dominica increased with increasing
the temperature up to 34°C and then it decreased with further temperature
increase.]]>Baldasari, N., A. Martin, S. Cavicchi and P. Baronio,2005Rhyzopertha dominica.]]>58131134Bashir, T.,2002Rhyzopertha dominica (F.)
