Last week, we discussed some common beneficial predators that help control pests on garden and landscape plants. One such predator you might find, is a lacewing. In fact, you may have seen adult lacewings on or near porchlights in the evening, since these insects are attracted to lights.
Green lacewing (Chrysopa spp., Chrysoperla spp.) adults are green, soft-bodied insects with golden eyes and four membranous wings. Their larvae are pale with dark markings and a tapered tail, and measure 1/8 to 4/5 of an inch long.
There are several species of green lacewings; some species have predaceous adults, while others feed only on.../h2>
Every April, we celebrate Earth Day and think about ways we can help make our planet healthier. One way to do this is to use IPM or integrated pest management to deal with pests around your home and garden!
IPM is a science-based, environmentally sound strategy that farmers, professionals, and residents can use to help prevent or control pests and their damage while at the same time protecting people, bees, beneficials, pets and the planet.
Are you already using IPM?
IPM uses a combination of methods including:
- biological control -- 'good bugs' or beneficial organisms like spiders or parasites that eat or prey on other bugs;
- physical control -- blocking the pest from...
If you see large black or golden-brown bees flying in your garden or landscape, don't be alarmed! These insects are most likely carpenter bees, and although their large size and loud buzzing can be intimidating, they are mostly harmless. Males can't sting and females rarely do, and both are considered beneficial because they are pollinators.
However, sometimes carpenter bees bore into lumber or trees to make nests and may damage structural wood or leave unsightly holes and stains. Multiple bees may use a common entry hole, tunneling several feet into wood to create chambers for their offspring.
The best way to manage carpenter bees boring into wood is through prevention. Use hardwoods in structures where possible...
Thanksgiving is a time to gather together with family and friends. The occasion is usually centered around a big meal followed by pumpkin pie, and hopefully some time to let each person share a list of what they are most grateful for that year.
Here at UC IPM, we are adding beneficial insects to our “thankful” list! These helpful invertebrates (also called natural enemies) are often overlooked for the contribution they make to gardens and landscapes.
Natural enemies, such as spiders and certain mites and insects, can help reduce the number of pests in your garden. It's possible that part of the reason they are overlooked is because...
June 15-21 is National Pollinator Week, a time to highlight the crucial role that pollinators play in producing food for our nation. Something you may not know about pollinators is that many of them, including beetles, flies, and wasps, are also beneficial natural enemies of many garden and landscape pests!
A good example of a pollinator that is also a natural enemy is the syrphid fly, also known as the flower or hover fly. Syrphid fly larvae prey on aphids and other soft-bodied insects, potentially consuming hundreds of these pests in one month! As adults, syrphid flies move from flower to flower feeding on pollen and nectar, assisting the process of...
