The impact of systemic insecticides on bees and other pollinators is not new phenomenon. Kansas State University Entomology Professor Raymond Cloyd says we, as an industry, need to work together to provide unbiased information that is based in sound science.
An understanding of both how thrips feed and how systemic insecticides work will go a long way toward effective control of these pests.
Pesticide resistance is always a concern because once an arthropod (insect or mite) pest population can no longer be adequately suppressed with existing pesticides, then management options become limited. Resistance is the genetic ability of some individuals in an arthropod pest population to survive an application or multiple applications of a pesticide. In other words,
Two-spotted spider mite, Tetranychus urticae, is still one of the most destructive mite pests of greenhouse-grown crops. Because it is so destructive, greenhouse producers use miticides to alleviate problems and avoid excessive mite outbreaks. Several commercially available miticides are called mitochondria electron transport inhibitors, or METIs, which disrupt the production of energy or adenosine triphosphate
Fungus gnats (Bradysia spp.) are major insect pests of greenhouse crops and can cause economic losses across a wide range of crops during stock plant, propagation and finished plant production. Female fungus gnat adults lay eggs in growing media, and the emerging larvae feed on the roots and crown. Fungus gnat management is an ongoing focus
Previously, I have written articles on the compatibility of alternative pesticides, primarily insecticides and miticides, with biological control agents or natural enemies such as parasitoids and predators. In general, natural enemies tend to be more susceptible to insecticides and miticides than insect and mite pests. However, fungicides are applied routinely in greenhouses to control both
Have you ever considered implementing a biological control program in your greenhouse operation? Well, first of all, what is biological control? Biological control involves the release or application of natural enemies including parasitoids (parasitic wasps), predators and pathogens (in this case entomopathogenic fungi and nematodes) into a greenhouse in order to regulate an existing insect
