Abstract
The banana pseudostem weevil, also known as Odoiporus longicollis
Oliver, is a significant pest of banana Plantation in Southeast Asia and is
widely distributed in India. Since numerous plants and their extracts have been
utilized for crop protection in traditional farming practices, it is generally
acknowledged that nature can offer solutions to crop protection problems. This
study examines the biopesticidal properties of betel leaf extract, neem oil
emulsion, and tobacco decoction on Odoiporus longicollis. For this, the
life cycle of O. longicollis was studied, and biopesticides designed to
assess the LC50, repellency, settling reaction, and mortality rate were applied
to the adults. The outcomes made it abundantly evident that the neem oil
emulsion is an effective biopesticide against O. longicollis. Even
though betel leaf extract is the least effective of the three biopesticides
that were developed, research on it are nevertheless important since they
reveal that, at higher concentrations, the extract can still be effective in
controlling pests. The previous research on O. longicollis is
insufficient, especially when it comes to the use of biopesticides. To close
information gaps and offer a methodical approach to pest management, the
current study set out to determine the concentration of bio-pesticide required
to control Odoiporus longicollis successfully.
