In the United States, pest thrips and plants they are most likely to damage include: Thrips are found all over the world and in every region of the United States. But for homeowners, the better advice is to avoid synthetic chemicals altogether and rely on the other methods of integrated best management. Thrips feed on plant or fungal tissue by piercing the outer layer of the organism and sucking out the contents of the affected cells. ; Mueke, J.M. ; Lei, Z.R. Observation on the onion thrips (Thrips tabaci Lind). Aluminum foil is also effective and may be suitable for a small garden; but it is expensive and difficult to reuse because it is delicate to handle. Unfortunately, we cannot provide individual solutions to specific pest problems. The abundance of thrips fluctuated annually over the three-year research. Petals may exhibit color break, which is pale or dark discoloring of petal tissue that was killed by thrips feeding before buds opened. Significant differences in maize grain crops were also found between 2013 and 2015, when there was a high abundance of thrips on the plants. The second, more frequent occurrence was confirmed in 2015, when 1 218 thrips were captured, 600 on non-Bt maize plants and 618 on Bt maize plants. Certain thrips occur on many different plants but damage only a few of the plant species on which they are found. And chemical pesticides are very likely to kill the predatory insects that are most helpful for controlling thrips. ; Griset, J.G. Centre for Biological Information Technology, The University of Queensland. Predatory thrips (Table 2), green lacewings, minute pirate bugs, mites, and certain parasitic wasps help to control plant-feeding thrips. Some varieties of thrips feed on fungal materials, leaf litter, debris, or other small arthropods. sharing sensitive information, make sure youre on a federal Their presence was affected by the maize growth phase and growing seasons and partially by the weather. The initial distribution of sticky traps in a monitored year occurred at the beginning of the second half of June when the BBCH was between 19 and 34 (nine or more leaves unfolded, four nodes detectable). ; Shields, E.J.

The occurrence of thrips was lowest in the second peak compared to both monitored years, and the most numerous species were: Subsequent increases in temperature and precipitation led to a gradual decrease in the occurrence of thrips on maize plants during the growth phase of maize BBCH 6567 (female stigmata fully emerged end male fully floweringmale flowering completed, female stigmata drying) in the second half of July and August. Integrated Pest Management for Floriculture and Nurseries. Behavior, body appearance, and host plants help to distinguish among thrips species (Table 1). As a result, we must assume that the effect of thrips monitored by sticky traps in our case was only marginal and had no significant impact on maize yield reduction. Furthermore, insecticide seed treatment use in soybeans has driven resistance to seed treatments for tobacco thrips in cotton. 3332. doi: 10.17221/177/2013-CJFS. These immature thrips are very active, feeding heartily on the plants and growing quickly through a series of metamorphic molts. Imidacloprid (Bayer Advanced Tree & Shrub Insect Control, Merit) commonly fails to provide satisfactory thrips control, and imidacloprid generally is not recommended for thrips. The site is secure. This may be a concern in fields planted to conventional soybeans, due to herbicide weed resistance. Adults are long and slim, slender, and have two pairs of wings with long fringes on the edges. The same patches can appear on petals where the pigment has been removed. Other studies showed no significant effect on seed cotton yields when thrips infesting cotton seedlings were controlled (Beckham, 1970; Cowan et al .
