Zoonotic malaria remains a significant public health concern in Malaysia, particularly in forested areas with active human, vector and macaque interactions. In Raub, Pahang, reported cases have increased in recent years. This study aimed to identify species within the Anopheles leucasphyrus group present in Hutan Simpan Sempam and assess their potential role in zoonotic malaria transmission. Mosquito sampling was conducted monthly from March to December 2025 using the outdoor human landing catch (HLC) method. The collected mosquitoes were morphologically identified and screened for Masmodian parasites using polymerase chain reaction (PCR). The relationship between human biting rate (HBR) and environmental variables was analysed using Spearman's rank correlation. A b A total of 214 Anopheles mosquitoes were collected, comprising 193 Anopheles introlatus (90.2%) 18 Anopheles maculatus (8.4%) and 3 Anopheles cracens (14%) Anopheles introlatus was the predominant species throughout the sampling period, with the highest abundance recorded in October (nm41), while the highest h at HBR w I was c observed in July (0.28 bites/ man/hour). The correlation analysis indicated that HBR increased with higher temperatures and wind speeds b s but decreased with increasing rainfall and relative humidity. This pattern suggests that climatic variables may contribute to variations in mosquito biting activity and seasonal abundance Futhermore, molecular analysis detected Plasmodium knowlesi and Plasmodiure coatney in An introlatus, confirming its involvement in parasite transmission. These findings indicate that An introlatus is the dominant species within the Leuccaphyrus group in Hutan Simpan Sempam and a potential vector of zoonotic malaria in Raub, Pahang, providing baseline evidence for future vector surveillance and targeted malaria control strategies
