How would spraying a yard with chemical pesticides to control insects be most likely to affect the diversity of insects found in it?

There would be fewer harmful insects and more beneficial insects in the yard.

Pesticides are chemical or biological substances which are added to reduce or prevent the growth of insects or pests in a agricultural or garden field. The action of a pesticide will be specific to the target pest and may not cause harm to desired species like pollinators. On spraying a yard with chemical pesticides to control insects will result in fewer harmful insects and more beneficial insects in the yard if the action of pesticide is specific to the harmful targeted pests.  

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
