"The enemy of my enemy is my friend" holds true in entomology as well!
The activity of natural enemies of pests (beneficial insects) is a key component of Integrated Pest Management in alfalfa to prevent pest resurgence and secondary pest outbreaks.
This is especially true for blue alfalfa aphid (BAA), a challenging pest in alfalfa (see companion article on managing BAA). Although BAA is frequently the most damaging and troublesome aphid to control, spotted alfalfa aphid, pea aphid, and cowpea aphid can also be problematic.

Western drywood termites (Incisitermes minor, Figure 1) are important pests of structural wood in California, causing millions of dollars in damage annually.

UC IPM Control options are generally categorized as either whole-structure treatment (heat-treatment and fumigation) or local treatments (insecticide injection into the wood, high-power microwaves, electrocution, and other techniques). Despite the high efficacy of fumigation, there has been increasing interest by property owners to use local treatments for eradicating drywood...

It has been rumored that Ben Franklin proposed the turkey as the national bird and symbol of our nation. Whether this is true or not, there is evidence that Franklin thought highly of this holiday bird. In a letter to his daughter, Franklin called the turkey a “respectable bird…though a little vain & silly, [he is] a bird of courage and would not hesitate to attack.”
In California, wild turkeys have started to become more common sightings in our communities. Some Californians may enjoy watching wildlife, but others find them to be quite the nuisance. Wild turkeys foraging for food in residential areas can destroy landscapes and gardens, leave their droppings on sidewalks and patios, and have been...
