Life Table and Intrinsic Rate of Increase of Sycanus collaris Fabricius (Heteroptera:Reduviidae), a Predator of Spodoptera litura (Fabricius) (Lepidoptera:Noctuidae)
The life table studies on Sycancus collaris FabriciusÂ (Heteroptera: Reduviidae) under laboratory conditions revealed thatÂ the net reproductive rate (R0) of the species was 30.46 female eggs/female. The true intrinsic rate of natural increase (rm) was 0.066. TheÂ population multiplied 1.59 times every week and the time taken forÂ the doubling of predator was 10.56 days. The total nymphal durationÂ was 49.3Â±1.95 days. The life span of females was more (45.17Â±1.83Â days) than males (31.83Â±2.48 days).
