Bokonon-Ganta, A.H., van Alphen, J.J.M., & Neuenschwander, P. 1996 Competition between Gyranusoidea tebygi and Anagyrus mangicola, parasitoids of the mango mealybug, Rastrococcus invadens: interspecific host discrimination and larval competition.. Entomologia Experimentalis et Applicata 79: 179-185.

Notes: No significant differences were found in the way each parasitoid species examined, attacked, stung, and oviposited into hosts, unparasitized, or previously parasitized by the other species; this suggests that neither species discriminates against each other; when A. mangicola was the first parasitoid to attack a host, it had no significant advantage over G. tebygi; however, when A. mangicola followed G. tebygi by either 4 or 24 h, it clearly won; overall G. mangicola won the competition in 70.9% of all cases; discussion of the coexistence of the two parasitoids as complementary for the biological control of the mango mealybug.
