Other claims from this paper (12)
- Observation The two Zygogramma beetle species, studied for biocontrol of Tithonia rotundifolia, had a short pre-oviposition period of 13-14 days.
- Observation The two Zygogramma beetle species had an incubation period of 4-5 days.
- Observation The two Zygogramma beetle species had a lifecycle of 40-45 days.
- Observation Longevity of Zygogramma piceicollis was 125 days.
- Observation Fecundity of Zygogramma signatipennis was 1146 eggs per female.
- Observation Fecundity of Zygogramma piceicollis was 1133 eggs per female.
- Observation Feeding, oviposition and development of both Zygogramma species were confined within the plant tribe Heliantheae.
- Observation Both beetle species showed a very strong preference for the invasive Tithonia rotundifolia.
- Observation The only non-target species supporting development to adulthood was the exotic weed Tithonia diversifolia.
- Observation Some sunflower (Helianthus annuus) cultivars were partially utilized by the beetles in host-specificity tests.
- Observation None of the tested sunflower cultivars supported complete development of the beetles.
- Recommendation The authors conclude that both Zygogramma species are suitable for release in South Africa against Tithonia rotundifolia.
