Miridae, Hemiptera, UV Light-traps, Sex-Ratio
We determined the sex-ratio of 1,095 plant bugs (Hemiptera: Miridae) taken from 60 individual UV light-trap samples in Clark County, Arkansas over a two year period. We found that of the 21 taxa in which a sex-ratio determination could be made, 61.9% of them (13 of 21) contained a majority (over 50%) of males. Three taxa were exclusively represented by males, while two taxa were exclusively represented by females. Although taxa dependent, our data indicate that male mirids are, in general, more frequently encountered in UV light-traps. However, contrary to the notion that sparked this study (see herein) light-trap content was not represented vastly to exclusively by male individuals as the sex-ratio of the cumulative data was 62.47% males (684) and 37.53% females (411).
