Other claims from this paper (9)
- Observation An attack on African mahogany trees (Khaya grandifoliola) by M. mutatus was reported for the first time in Brazil.
- Association The attack indicates a preference of M. mutatus for Khaya trees with larger diameters.
- Mechanism Colonization of Khaya by M. mutatus was impeded by gummosis, a plant defense mechanism.
- Observation The overall attack rate on Khaya was low.
- Observation Nearly all attacks on Khaya failed to produce progeny.
- Observation Megaplatypus mutatus exhibited a multivoltine life cycle in the study region.
- Observation Most specimens captured in traps baited with the M. mutatus sex pheromone were females.
- Observation Adults of neither sex of M. mutatus responded to traps baited with ethanol.
- Recommendation The authors recommend regular monitoring of Khaya plantations for M. mutatus infestations to mitigate impacts on tree health and timber value.
