Bioactivity Studies of Solanum ferox L. Against Tribolium castaneum (Herbst) Adults

Abstract

Dose-mortality and repellent activity tests of the chloroform extracts of fruit, leaf, root and stem of Solanum ferox L. against the red flour beetle Tribolium castaneum (Herbst) adults have been done. The fruit, leaf and stem extracts offered promising toxicity to the beetles within 30 min. of exposure. The LD 50 values for 30 min., 12, 24, 36 and 48h of exposures were 0. 440, 0.247, 0.211, 0.207 and 0.164mg cm -2 respectively for the fruit extract; 2.394, 1.712, 1.540, 1.239 and 0.993mg cm -2 respectively for the leaf extract; and 4.918, 0.871, 0.546, 0.472 and 0.522mg cm -2 respectively for the stem extract. However, the root extract did not offer any mortality for 30 min. and 12h of exposure; and thus the LD 50 values for 24, 36 and 48h of exposure were 6.667, 5.086 and 3.357mg cm -2 respectively. While the dose-mortality activity can be arranged in the order of fruit> leaf> stem> root extracts. The fruit and stem extracts showed repellent activity against T. castaneum adults at P<0.01 and the leaf extract at P<0.05 level of significance, while the root extract did not show any repellency.

Physicochemical and Sensory Characteristics of “Terong Asam” (Solanum ferox Linn) Dry Sweetmeat at Various Concentrations of Sugar

“…Its local name is "Terong asam", belongs to the Solanaceae family, the stems have fine thorns, and the community uses the fruit as a cooking flavour (Hazimah et al, 2018). The fruit contains water, carbohydrates, protein, fat, fiber, minerals and vitamins (Abdullah et al, 2012). The difference of fruit between "terong asam" and eggplant is the round shape and when it is ripe, it is orange with thick fruit and a slightly sour taste.…”
