Cycas taitungensis Shen, Hill, Tsou & Chen (Cycadales: Cycadaceae) is an endangered species in Taiwan and it has been attacked by Aulacaspis yasumatsui Takagi (Hemiptera: Diaspididae), a mayor pest of Cycad plants. Its natural enemy, Cybocephalus flavocapitis Smith (Coleoptera: Cybocephalidae) development time was evaluated in this study, and egg duration, immature development time at five constant temperatures was also tested. Egg period ranged from 31 days at 15oC to 4 days at 35°C, no development was completed at 15 and 30°C. Immature development time ranges from 71 days at 20oC to 29 days at 30oC. Lower threshold temperature for all stages is between 11-15oC. For reach adulthood, 490 degree-days are necessary. Pre-pupae and pupae together are the longest period in which no predation occurs.
Occurrence data of C. flavocapitis and C. nipponicus at 34 localities were sampled in 10 counties across Taiwan. Five distribution maps were modeled using Maximum Entropy Modeling (Maxent). The number of C. flavocapitis collected is consistent with the Maxent model; Yilan and Kaohsiung are the counties with high percentage of better conditions and high number of beetles. Pingtung and Taichung counties have 57 - 91% of suitability and C. nipponicus was more abundant as well. The Taiwan Cycad Nature Reserve’s conditions are not favorable for C. nipponicus; the search of other control agents using predicting models, and evaluate the agent’s effectiveness must be done before the potential control agent is released.
