Summary of 4-ref-cytotypes (4RCTs) and male and female crossing types (<i>mod</i> and <i>resc</i> abilities) identified among the 51 <i>Culex pipiens</i> isofemale lines infected with the five <i>w</i>Pip groups.

The cytotypes were determined based on reciprocal crosses between the 51 isofemale lines and four reference laboratory lines (see text): Lv (wPip-II), Mc and Sl (wPip-III) and Is (wPip-IV). C = compatible cross (all hatching rate, HR >90%); IC = incompatible cross (bolded cells, HR = 0%).
