Of 231 adults of Aptesis grandis that emerged from cocoons of Neodiprion huizeensis , the female to male ratio was 1.2: 1. The average parasitism rate of Neodiprion huizeensis by Aptesis grandis was 3.8%. Adults of Aptesis grandis emerged between 20th February to 9th March under laboratory conditions.
