Medicinal plants are an important source of bioactive compounds that have various biological effects on
pests and diseases of agricultural and livestock importance. The present study evaluated the nematicidal
and insecticidal effects of the acetone extract (E-Ac) of Prosopis laevigata leaves. The tests were carried
out under in vitro conditions. E-Ac had 100% nematicidal activity against Haemonchus contortus at 40
and 20 mg/mL, while at 10 mg/mL it had nearly 60% mortality against L3 H. contortus larvae. When
E-Ac was incorporated into an artificial diet, it had an 88% insecticidal effect against Melanaphis sorghi
at 72 h at 10 mg/mL. The phytochemical profile of E-Ac revealed the presence of alkaloids, flavonoids,
coumarins, tannins, sterols/terpenes and saponins. The results of the present study reveal that E-Ac
has secondary metabolites with anthelmintic activity against L3 larvae of H. contortus and insecticidal
activity against adults of M. sorghi, which could represent a viable and affordable allelopathic tool in the
control of gastrointestinal nematodiasis in small ruminants and against aphids of agricultural importance.
