TOXICOLOGICAL AND BIOCHEMICAL IMPACT OF SOME BIOINSECTICIDES AGAINST THE LARVAE OF THE RED PALM WEEVIL, Rhynchophorus ferrugineus (OLIVIER) UNDER LABORATORY CONDITIONS |  UTTAR PRADESH JOURNAL OF ZOOLOGY

The red palm weevil (RPW), Rhynchophorus ferrugineus (Olivier) (Coleoptera: Curculionidae), is a major pest of date palms, inflicting significant economic damage. This pest has been managed using a variety of control approaches. The intensive use of conventional insecticides to control RPW has successfully reduced the quantity of weevils, but they are still hazardous to the ecosystem since they create pollution and harm to other beneficial organisms. The current study sought suitable, effective, and safe alternative control methods. Furthermore, the effect of the studied substances on the enzymatic activity of third instar larvae was measured spectrophotometrically. Under laboratory circumstances, four commercial pesticides were treated to RPW 3rd instar larvae and the LC50 values were estimated. Larvae that survived treatment were collected 24 hours later and prepared for enzymatic activity examination. All experiments were conducted at the Wood and tree scavenger research department, the Plant protection research institute, and the Agricultural research centre. According to the low LC50 value obtained, Dr. Sure® was the most hazardous chemical. Furthermore, the results demonstrated that BIO-MAGIC® was the least harmful due to its high LC50 value when compared to the other chemicals. Furthermore, the data demonstrated substantial effects on detoxifying enzymes in 3rd instar larvae fed with the LC50 of examined chemicals as a protective response to those compounds. These findings demonstrate the effectiveness of non-conventional pesticides in controlling the youngest larval instars.
