<![CDATA[ARTICLE HIGLIGHTS- Forest moth diversity is higher than in other zones (CCA)- Moth-host plant relationship revealed by PCA- Two polyphagous pests found in different zones - Invasive weed dominates and affects moth diversityABSTRACTMoths show a habitat preference for the Ranu Darungan Resort, a conservation area within Bromo Tengger Semeru National Park (BTSNP). The phenomena of Mount Semeru's eruption and anthropogenic activities can pose a threat, causing damage to primary and secondary forests, which leads to a reduction in vegetation cover and host plants. This research aims to analyze the structure of the moth community and identify potential host plants at the Ranu Darungan Resort. We documented ten moth species and thirty-eight plant species. Research has documented the wide host range of Conogethes punctiferalis (jungle zone) and Duponchelia sp. (utilization zone), which encompasses various agricultural and forestry plants. The data analysis indicates that the Jungle Zone has higher species diversity (Shannon-Wiener Index: 2.332) than the Utilization Zone (2.244). In contrast, the data show slightly higher species evenness in the Utilization Zone (1.05 vs. 1.03). Both zones demonstrate low dominance and high community similarity. Ageratina riparia, an invasive plant that spreads rapidly, dominates both habitats and can easily dominate new ones. Canonical Correspondence Analysis showed that Asota heliconia, Plodia sp., Conogethes punctiferalis, and Eacles sp. significantly correlate with soil moisture, light intensity, wind speed, and air humidity in the jungle habitat. Principal Component Analysis revealed a strong correlation between Clidema hirta, Crytococcoum patens, and Ageratina riparia in the same habitat. Our findings demonstrate that moth presence directly depends on the availability of potential host plants, highlighting the importance of plant diversity in sustaining moth species richness.]]>
