Weed CharacteristicABSTRACT. The effectiveness of herbicide to control weeds is determined by type and dosage of herbicide. This research aimed was to study the accurate type and dosage of herbicide to control weeds on soybean of argomulyo cultivar. Herbicide type and dosage tested were clomazone and pendimethalin, and 0; 0.75; 1.50; and 2.25 kg a.e.ha-1 respectively. To understand the effect of both factors on the effectiveness of herbicide, Randomized Completely Block Design was employed. The variables observed were weed control percentage, weed coverage percentage, and weed species. The result showed that application 2.25 kg a.e.ha-1 of herbicide increase the percentage of weed control on Cleome rutidospermae and Ipomoea triloba but decreases weed coverage percentage. Meanwhile pendimethalin herbicide simply raises the control percentage of Cleome rutidospermae

Meanwhile, age-specific survival curves (lx) shows the survival rate of type I. The highest reproductive value (Vx) was achieved by adult females at the age of 10 days, and the total value for the entire reproductive age is 1335.42. Incubation period of C. coeruleus eggs was 7 days. Larval stages I through IV each lasting for 6.06; 5.5; 6.11; 8.43 days. Pupa stage lasts for 6.66 days. Adult males can live for 49.08 days, while females for 76.99 days. During his lifetime, the female passes the pre-oviposition period for 10.57 days, 30.26 days during the period of oviposition, and post-oviposition period of 24.58 days long. Comparison between the number of males and females is 1: 2.83 (males 24, females 68). Breeding C. coeruleus in the laboratory can be done using the prey P. marginatus as alternative prey. C. coeruleus in papaya planting area, where P. marginatus are, allegedly to settle but certainly needs further exploration on the local alternative prey
