Abstract
Corcyra cephalonica (Lepidoptera) is an important storage product pest that damages rice, corn and other grains. Habrobracon hebetor is a parasitic wasp that is capable of paralyzing lepidopteran pests. However, how C. cephalonica affects the prey preferences, fitness, and functional response of H. hebetor remains poorly understood. We therefore used selective and nonselective, age–stage two-sex life tables and functional response models to determine how this problem could be solved. Our results showed that H. hebetor preferred the 4th to last instar larvae of C. cephalonica and that its functional responses were consistent with the Holling II model in these three instars. However, the search ability of the 4th instar larvae was strong and its processing time was short. Additionally, generative development can be completed in the 4th to last instar larvae stage of C. cephalonica, whereas the 5th instar provided wasp predators with the best life history, population and paralysis rate parameters measured in this study. We also found that the wasp displayed its highest population size and total paralysis rate within 60 days on 5th instar prey. Thus, we conclude that 5th instar larvae are a suitable host for H. hebetor. These results not only provide a theoretical reason to use H. hebetor to control C. cephalonica infestation but also broadens the known host larvae selection range for industrial production of this parasitic wasp.

Description of the data and file structure
File and variables
File: selective test and non-selective test
Description:The selective and non-selective trial folders contain folders named first instar, second instar, third instar, fourth instar, fifth instar and last instar respectively. The first line in each folder represents the instar (stage), and the remaining numbers in each row represent the number of paralyzed larvae of this instar of Corcyra cephalonica under each repeated trial.
File: Fitness test
Description: The fitness folder contains 3 folders: Paralysis parameters of F1 generation of H.hebetor, Life table parameters of F1 generation of H.hebetor and Life table parameters of parental H.hebetor, and each folder contains the original data of H.hebetor that lay eggs or paralysis of the fourth instar, fifth instar and last instar larvae of the rice moth respectively under the corresponding name of the folder. These three files write the original data in the standard format of life table and paralysis rate respectively and where anyone who uses them will understand the layout. Towsex-MSChart and Consume software can be used to get the life table of the parental and F1 generation of H.hebetor and the graphs of population growth and paralysis rate growth.
File: Functional response
Description: The first column of the file represents host instar, the second column represents host density, the numbers followed by treatment respectively represent the number of treatments, and each subsequent column represents the number of paralyses of H.hebetor paralysing on rice moth larvae under this treatment. A total of 10 treatments.
File: Density of female.txt
Description: In the Density of female file, the first column represents the density of female, the second column represents the host density, and each subsequent column represents the rational number, and each treatment represents the number of paralysis of rice moth larvae by H.hebetor under different female densities. There are separate tabs for different instars.
Code/software
- Fitness data were analyzed using age-stage tow-sex life tables.
- Functional response data was analyzed using SAS software.
- The selective and non-selective test data were analyzed using Towsex-MSChart software.
- The female density data set was analyzed using SPSS software.
