Other claims from this paper (11)

Observation Host-specificity testing was completed for Actinote thalia pyrrha.
Observation Host-specificity testing of Calycomyza sp. was nearly complete and encouraging.
Observation The host range of A. thalia thalia was investigated.
Method / resource Rearing techniques and biology were determined for Conotrachelus reticulatus.
Method / resource Rearing techniques and biology were determined for Longitarsus horni.
Observation Breeding Melanagromyza eupatoriella failed in several attempts.
Recommendation Conotrachelus reticulatus was substituted for Melanagromyza eupatoriella because of a similar functional niche.
Recommendation Polymorphomyia basilica may substitute for Cecidochares connexa, which seems incompatible with the South African C. odorata biotype.
Observation Host-specificity tests found Leptocysta sexnebulosa unsuitable for release.
Observation Breeding Adaina sp. nov. was difficult.
Observation Breeding Mescinia sp. nr parvula was difficult.
