non-target arthropods are generally

non-target arthropods are generally neutral, i.e., having neither
negative nor positive impacts on the populations of species under
consideration (Romeis et al., 2006; Marvier et al., 2007; Duan et al.,
2008; Wolfenbarger et al., 2008; Naranjo, 2009). However, Lövei
et al. (2009) reported there could be negative effects on natural
enemies. This latter paper resulted in an exchange of views relating
to the validity of the analyses used in the different studies (Shelton
et al., 2009; Andow et al., 2009), and not surprisingly, this question
is the subject of an ongoing debate (Duan et al., 2010).
