description |
The utilization of plant extracts as botanical insecticides does not
only affect the mortality rate, but also the development of the insect�s life
stages. The aim of this study was to determine the effect of the Madura
tobacco leaf extract in sublethal concentrations on the development and
reproduction of the beet armyworm Spodoptera exigua. The test design
was a completely randomized design (CRD), with four sublethal
concentrations, i.e. LC50, LC25, LC12,5, LC6,25, and one control replicated five
times. The results showed that: (1) the sublethal concentration (0.1%) had
significant effect on the growth phase and life duration of the second
instar larvae of S. exigua compared to the control, (2 ) the higher the
concentration, the shorter the age of larvae, adult, and the eggs, (3) the life
duration of the various treatments and control was 24.48 to 26.92 days, (4)
the percentage of the success of the larvae until adult and the barrier of
the weight between the treatments was similar, and (5) the concentration
treatments do not significantly influence the reproduction variable. |
