The field of animal behavior has experienced a surge of studies focusing on functional differences among individuals in their behavioral tendencies (‘animal personalities’) and the relationships between different axes of behavioral variation (‘behavioral syndromes’). Many important developments in this field have arisen through research using insects and other terrestrial arthropods, in part, because they present the opportunity to test hypotheses not accessible in other taxa. This chapter reviews how studies on insects and spiders have advanced the study of animal personalities by describing the mechanisms underlying the emergence of individual variation and their ecological consequences. Furthermore, studies accounting for animal personalities can expand our understanding of phenomena in insect science like metamorphosis, eusociality, and applied insect behavior. In addition, this chapter serves to highlight some of the most exciting issues at the forefront of our field and to inspire entomologists and behaviorists alike to seek the answers to these questions.

Tomato hybrids obtained from homozygous progeny of line 30-4, engineered for Tomato spotted wilt virus (TSWV) resistance, were tested under field conditions in two locations with their corresponding nontransgenic hybrids. No transgenic hybrid became infected, but 33 to 50% of plants of each nontransgenic hybrid became infected with a severe reduction of marketable fruit production. The transgenic hybrids conformed to the standard agronomic characteristics of the corresponding nontransgenic ones. Fruit were collected from the nontransgenic plots included in the experimental field and from border rows, and seed were used to estimate the flow of the transgene via pollen. No transgene flow was detected in the protected crops; however, in the open field experiment, 0.32% of tomato seedlings were found to contain the genetic modification. Immunity to TSWV infection in 30-4 hybrids was confirmed in laboratory conditions using mechanical inoculation and grafting. Thrips inoculation in leaf discs of line 30-4 demonstrated that TSWV replication was inhibited at the primary infection site but not in leaf discs of a commercial hybrid containing the naturally occurring resistance gene Sw-5. Due to the high economic value of tomato crops worldwide and the importance of TSWV, the engineered resistance described here is of practical value for breeding into cultivars of commercial interest, because it could be combined with naturally occurring resistance, thus greatly reducing the ability of the virus to develop resistance-breaking strains.
