Introduction
Stink bugs are insects that belong to Pentatomidae family known for their ability to emit an unpleasant odor as a defense mechanism. These bugs spend most of their time feeding on plants, mainly fruits and vegetables, which made many gardeners consider them as pests that can cause significant damage to their crops. However, recent studies suggest that stink bugs might not be entirely harmful to plants as previously thought.
Stink bugs and plant pollination
Although stink bugs are infamous for their feeding habits, they might play a role in plant pollination as well. A study conducted by the USDA-ARS in 2014 found that stink bugs, especially the brown marmorated stink bug, can transport pollen from one plant to another. The researchers found that stink bugs' legs contain a considerable amount of pollen, indicating that they accidentally transfer it from their feeding on one plant to another, which could play a significant role in cross-pollination.
Stink bugs and natural pest control
Although stink bugs might feed on plants, they could also contribute to natural pest control in gardens. A study published by the University of Florida in 2018 found that stink bugs can play a significant role in controlling pests such as caterpillars and aphids that feed on plants. The researchers found that the brown marmorated stink bugs can feed on and kill these pests, which could prevent them from causing significant damage to crops. Therefore, having a few stink bugs in the garden might not be such a bad idea.
The benefits of stink bug corpses
Stink bugs, like most insects, die eventually. However, their dead bodies could also benefit plants. A study published in the journal PLOS ONE in 2018 found that when stink bugs are plentiful, their dead bodies can provide nutrients to plants. The researchers found that the nitrogen and phosphorus content in plants located near stink bug corpses increased by up to 30 percent. The study concluded that stink bugs might not be entirely harmful to plants and could even provide them with essential nutrients.
Conclusion
Despite their bad reputation as pests, stink bugs might not be entirely harmful to plants. Stink bugs can contribute to plant pollination, natural pest control in gardens, and even provide plants with nutrients when they die. Therefore, before considering stink bugs as a problem in your garden, it is essential to understand their potential benefits and how they contribute to the ecosystem.
