title: Habrobracon hebetor ectoparasitism paralyzing effect on Corcyra cephalonica of different instar larvae

description: 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.

 [https://doi.org/10.5061/dryad.5mkkwh7gc](https://doi.org/10.5061/dryad.5mkkwh7gc) ## 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 1. Fitness data were analyzed using age-stage tow-sex life tables. 2. Functional response data was analyzed using SAS software. 3. The selective and non-selective test data were analyzed using Towsex-MSChart software. 4. The female density data set was analyzed using SPSS software. ## Access information Other publicly accessible locations of the data: * n/a Data was derived from the following sources: * n/a
