Greenhouse Pest 101: Western Flower Thrips

Western flower thrips (Frankliniella occidentalis) are one of the most, if not the most, serious pests of greenhouse floricultural crops. Although the insects’ actual feeding causes damage to leaves and flowers, the most serious consequence of an infestation is that thrips can spead the tomato spotted wilt virus (TSWV) and impatiens necrotic spot virus (INSV). Both of these viruses are serious problems for a greenhouse grower and can cause large-scale losses of plants. Western flower thrips (WTF) feed on most major greenhouse ornamentals, including chrysanthemum, gerbera, fuchsia, petunia, impatiens and roses, as well as hundreds of other plants species. There are six stages in the thrips’ lifecycle: eggs, which are deposited within the leaves, flowers or bracts, two larval stages, prepupae, pupae and adult. The second-stage larvae are quite active, jumping and crawling on the surface of the leaves. Monitoring For Thrips Monitoring for WTF is essential. By the time […]

Biological Controls And Pesticides Can Work Together

Some growers are interested in combining natural enemies — biological control agents, such as parasitoids and predators — with pesticides, which in this case include insecticides and miticides. The goal is to regulate arthropod (insect and mite) pest populations and avoid or minimize plant damage. Combining the two methods may also lead to a reduction in pesticide applications and, thus, fewer problems associated with pesticide resistance. It is important to understand, however, that some pesticides may have direct or indirect effects on natural enemies after exposure. Pesticides And Natural Enemies The impact of pesticides is not solely based on direct effects like mortality. It is also not uniquely based on contact exposure or odors that influence behavior, which affect the ability of natural enemies to locate prey (hosts) on plants. Pesticides may have indirect effects, sometimes referred to as sub-lethal or chronic effects. These effects consist of inhibiting host foraging […]

Why Mid-American Uses Biopesticides

Tom Costamagna has a unique perspective on using biocontrols in ornamental crops. After starting his career in biologicals research at University of California-Davis, he joined Mid-American Growers as director of plant quality. We asked him why he’s committed to making bicontrols a significant part of Mid-American’s production process. GG: Why do you think biocontrols are a more realistic option for growers now? Costamagna: In the last five to eight years, the numbers of new chemistries being registered is few and far between, so we need new options. Also, you see the success stories with the influx of biologicals being used in vegetables. I think that’s a driving force as well. Most importantly, we’re moving forward on the learning curve. Whether it’s new genetics or new pest control tools, when you try anything new, in the beginning you’re going to have fewer success stories than failures. You see some of the […]

Benefit From Beneficial Nematodes

With a variety of factors driving pest management changes in horticultural operations, many professionals are looking to expand their use of biological control agents (BCAs), including the use of beneficial nematodes. Growers find beneficial nematodes to be an attractive addition to existing pest management programs because they reduce or eliminate restricted-entry intervals, have limited impact to worker and customer safety, promote environmental stewardship and are valuable pesticide resistance and residue management tools. While great strides have been made in the development of effective beneficial nematodes over the past several years, there is still confusion among growers about these little worms. How do they work? Do they cause damage? How should I use beneficial nematodes in the greenhouse? Read on to learn the answers to these questions and more. How Beneficial Nematodes Work Beneficial nematodes, also known as entomopathogenic nematodes or insect-parasitic nematodes, are microscopic, un-segmented roundworms. They are naturally-occurring and […]
