Insects and Bacteria Appear to Team Up Against a Pesticide

question 31

Multiple Choice

Insects and bacteria appear to team up against a pesticide that is commonly sprayed on crops. The bean bug Riptortus pedestris is a common soybean pest and in a recent study was shown to acquire resistance to a common insecticide. This resistance is related to the presence of bacteria ( Burkholderia sp.) living within its gut. In this mutually beneficial relationship, more than 100 million bacteria can live within the insect's gut. Evidence suggests that these bacteria are able to break down the pesticide into carbon dioxide, which is used by the bacteria, and harmless waste products are then secreted. In a recent study, researchers fed bacteria-infested bean bugs and bacteria-free bean bugs a diet of soybean seedlings that had been treated with the pesticide. Most of the bacteria-infested bean bugs survived after eating the treated soybeans, but 80 percent of the bacteria-free bean bugs died. Carbon dioxide, which is a breakdown product of the pesticide, is likely used by the bacteria for which of the following?

• A) an energy source
• B) cell structure
• C) to carry genetic information
• D) both an energy source and cell structure
