Light intensity (adaptation), circadian periodicity and photoperiodism are highly associated with the behavioral responses of insects. Artificial light at night can interfere with the nocturnal behavior of insects and their growth and physiology. This study investigates the impact of artificial light on the diversity and community composition of noctuid moths in Multan, Pakistan, while considering the role of seasonal environmental factors and habitat. Moths were collected using light traps of different intensities installed in both crop and forest areas over a one-year period. Our results revealed a pronounced habitat-specific effect, with the maximum species diversity (H’=2.443), richness (4.152), and evenness (1.00) recorded from traps placed in crop areas. Conversely, the lowest diversity metrics were observed from traps in other locations, suggesting that light intensity interacts with habitat characteristics. A total of 16 noctuid species were identified, with community composition varying significantly between trap locations. The crop area harbored a more diverse assemblage, including species like Spodoptera exigua, Spodoptera litura, and Hadena trifoli while the forest area traps showed lower species richness. Seasonality was a critical factor, with peak moth populations observed in October and May. This period correlates with favorable environmental conditions and the presence of key host crops such as maize and wheat, which support noctuid populations. Conversely, minimal activity was recorded during the unfavorable conditions and host scarcity of December and January. The study concludes that while artificial light intensity is a factor in attracting and potentially disrupting nocturnal insects, its impact is strongly modulated by habitat type (crop vs. forest) and seasonal environmental conditions, particularly host plant availability. The findings highlight that crop areas, with their abundant food resources, can support higher moth diversity even under light trap pressure, underscoring the complex interplay of anthropogenic and natural factors in shaping nocturnal insect communities.
