Insecticidal Effect of Piper guineense Seed Powder in the Control of Beans Weevil Callosobruschus maculatus (Fabr)
Piper guineense commonly called Usira in Edo, Uziza in Igbo and IgherelIyere in Yoruba belongs to the family piperaceae. The efficiency of its seed powder in the control of callosobruschus maculatus (beans weevil) was investigated in the Science Laboratory Department of Federal Polytechnic, Auchi, Edo State Nigeria. The seed powder was applied at the rate of O control, 15, 25, 50 and 100 (gkg-1). The result obtained shows that piper guineense seed powder at 25gkg-1 to 100gkg-1 were effective in the control of callosobrusus maculatus at 0.01% level of significance. It was revealed that a very strong insecticidal action of I. piper guineense on beans weevil. However, the efficiency of this insecticidal action on callosobruschus maculatus with increasing concentration of the plant material seed powder with 100gkg-1 giving the highest mortality rate, residual action and egg plugs of the weevils. This finding is critical to resource poor farmers in developing countries who will find this trial practicable and affordable. colourkasi hustlers.
 
UDEEP: Edge-based Computer Vision for In-Situ Underwater Crayfish and Plastic Detection
Invasive signal crayfish have a detrimental impact on ecosystems. They spread
the fungal-type crayfish plague disease (Aphanomyces astaci) that is lethal to
the native white clawed crayfish, the only native crayfish species in Britain.
Invasive signal crayfish extensively burrow, causing habitat destruction,
erosion of river banks and adverse changes in water quality, while also
competing with native species for resources and leading to declines in native
populations. Moreover, pollution exacerbates the vulnerability of White-clawed
crayfish, with their populations declining by over 90% in certain English
counties, making them highly susceptible to extinction. To safeguard aquatic
ecosystems, it is imperative to address the challenges posed by invasive
species and discarded plastics in the United Kingdom's river ecosystem's. The
UDEEP platform can play a crucial role in environmental monitoring by
performing on-the-fly classification of Signal crayfish and plastic debris
while leveraging the efficacy of AI, IoT devices and the power of edge
computing (i.e., NJN). By providing accurate data on the presence, spread and
abundance of these species, the UDEEP platform can contribute to monitoring
efforts and aid in mitigating the spread of invasive species
