Stink Bugs Prefer the Hot Weather

When it comes to Stink Bugs, recent studies have discovered that temperature is the most important factor affecting their numbers and where they choose to set up housekeeping.

While many of us complain about the heat — more and more as it gets hotter and hotter — stink bugs actually prefer the heat!

Stink Bugs Prefer the Hot Weather

Entomologists used complex spatial and statistical analyses to determine that temperature is what is responsible for the patterns of Stink Bugs. The study identified differences in thermal tolerances among both native and invasive stink bugs.

The researchers conducted a survey of three types of Stink Bugs:

  1. The invasive Brown Marmorated Stink Bug (BMSB)
  2. The Green native Stink Bug
  3. The Brown native Stink Bug

They looked at these in Soybean fields in Maryland, Virginia, West Virginia, and Delaware.

They discovered that the number of Marmorated Stink Bugs became lower as the temperatures went up in June. In fact, none were found in fields with average June temperatures that were higher than 74° Fahrenheit. However, the abundance of the native Stink Bugs increased as the temperature increased.

This study is the first comprehensive large-scale survey that quantifies the interactive roles of the environment, resource availability, and distance from the source population on the pattern of distribution and abundance of Stink Bugs. Previous studies done on the Marmorated variety examined these factors mostly in isolation.

Additionally, this study clearly identifies the spatial scale at which each of these factors function, and it is the first to distinguish the roles of environmental and landscape factors on invasive versus the native variety.
