Abstract:\u00a0<\/strong><\/span><\/p>\n

The study was conducted in the Biology Laboratory of the College of Education Radfan – University of Lahj, for the year 2022 AD to evaluate the efficiency of the aqueous extract of C. Papaya<\/em> leaves and seeds; as a larvicide; For the early fourth lifespan of C. pipiens mosquitoes at concentrations (0.75, 0.5, 0.25, 0.0 and 1%) for exposure periods (4, 12, 8 and 24 hours). The experiment was carried out in a completely randomized design with four repetitions. The results indicated that the seed sample was significantly superior to its leaves in death rates %, reaching 53.13% and 43.25%, respectively, at a probability level of 5%, and the concentrations used caused a significant increase in death rates % compared to the control treatment (0%), and that the concentration (1%) had The apparent effect, their percentages reached % for the two samples (97.50, 87.50%), respectively, at the highest exposure time, and % death rates increase with increasing exposure time. The highest percentage of seeds was 67.00 and 57.75% for leaves for 24 hours. The calculated LC50 values \u200b\u200bfor papaya seed and leaf extract were 0.303 and 0.469 % at the time of 24 hours.<\/span><\/p>\n
