Effects of Social Environments and Female Life History Traits on Sex Allocation in a Spider Mite

Sex allocation in spider mites (Tetranychus sp.) is of interest to many researchers. They are haplodiploid species where the mated females can lay fertile and infertile eggs that develop to daughters and sons, respectively. Females tend to fertilise larger eggs (Macke et al. 2011) and adjust the offspring sex ratio under various social environments (e.g., population size and density) (e.g., Weerawansha et al. 2022a, 2022b, 2022c).
