Termiticidal Potential of Parkia biglobosa Aqueous Seed Extract Rates and Location on Termites Infestation in Niger State, Nigeria

Abstract

Termites constitute a nuisance to both the environment and human properties anywhere they exist. Consequently, this research was conducted at Mokwa Local Government area of Niger State to evaluate the rate of bio-insecticide for their control. Mokwa is located on latitude 09˚ 18ˡN and longitude 05˚ 14ˡE in Southern Guinea Savanna agro ecological Zone of Nigeria. This experiment was aimed at determining the termiticidal potential of acqueous solution rates of locust bean tree (Parkia biglobosa) seed and location on termites῎. The main treatments were four Parkia biglobosa seed extract rates at 0, 5, 10, and 15 millilitres while the sub treatments were three termites locations at Mokwa, Muwo and Kudu. The trial was factorially combined in a 4 x 3 arrangement and fitted into a completely randomized design (CRD) with three replications. Data collection were on number of termite per meter of tunnel, length of tunnels in meter, number of life termites and the number of dead termites found after treating with the extract solution rates. The result showed that Parkia biglobosa seed extract rates differed significantly on termites’ mortality rate irrespective of the location. Moreover, the Parkia biglobosa seed extract rates had significant effect on termites throughout the period of the study. The P. biglobosa seed extract rates at 10 and 15 millilitres were effective for the control of termites in all the test locations and are thus suggested for use as an alternative to synthetic termiticides in the Southern Guinea Savanna zone of Nigeria for termite control.
