Biological Activities
Compounds
Conditions
Syncolostemon welwitschii, also referred to as Hemizygia welwitschii, exhibits significant insecticidal properties against the pest Callosobruchus maculatus. The hexane, acetone, and methanol extracts derived from its leaves serve as effective agents for protecting stored cowpea from these insects. At a dosage of 10 g/kg, the hexane extract completely prevented the emergence of F1 progeny from the treated seeds. Acetone and methanol extracts similarly provided near-complete inhibition of progeny emergence at this highest concentration. Furthermore, these botanical extracts significantly reduced the physical seed damage caused by Callosobruchus maculatus during long-term storage.
Preparations
Syncolostemon welwitschii is prepared as acetone extracts to assess their individual insecticidal activities against stored grain pests. The plant is also prepared as hexane extracts, which were found to completely prevent the emergence of F1 progeny in certain bioassays. Additionally, Syncolostemon welwitschii is prepared as methanol extracts to evaluate their effectiveness in protecting cowpea seeds. All three types of extracts, including the acetone, hexane, and methanol preparations, demonstrated high efficacy in controlling Callosobruchus maculatus. These specific extraction methods serve as a viable basis for developing pest management programs in developing countries.
