Brown marmorated stink bug (BMSB), Halyomorpha halys, within the complex of Pentatomidae pests within Florida tomato, peach, and various small organic vegetable crops

Stink bugs (Hemiptera: Pentatomidae) represent significant agricultural pests across Florida’s diverse cropping systems. We investigated the spatiotemporal dynamics and species distribution of stink bugs in agricultural ecosystem by analyzing two large multi-year and multi-crop survey stink bug datasets across six Florida counties, including Collier, Hendry, Lee, Manatee, and Lake. The two comprehensive datasets were tomato-specific survey (5,559 observations) and a multi-crop survey (8,467 observations), both characterized by substantial zero-inflation (91.8% and 72.3% zeros, respectively) and overdispersion (dispersion indices of 6.29 and 5.94). Zero-inflated negative binomial models accounted for these data characteristics. Results revealed distinct species composition patterns across crop types, with Euschistus servus, Nezara viridula, and Murgantia histrionicadominating in the multi-crop data, while N. viridula predominated in tomato systems. Significant seasonal and regional variation in stink bug abundance was observed, with higher counts during warmer seasons and in southern regions. Trap type efficacy varies by species, with yellow pyramid traps capturing more N. viridula and Thyanta custator.
