Spider mites damaging some soybean [PDF]
Twospotted spider mites are serious pests whenever hot, dry weather persists. Large spider mite populations may develop on both soybean and corn. Injury to soybean has been seen near Atlantic in southwestern Iowa.

BackgroundThe two-spotted spider mite, Tetranychus urticae, is an extreme generalist plant pest. Even though mites can feed on many plant species, local mite populations form host races that do not perform equally well on all potential hosts.

Optimized use of UV‐B light to suppress Western flower thrips in controlled environment tomato crops
Visual representation of study into the use of UV‐B light to simultaneously attract and suppress Western flower thrips in controlled environment crops. Abstract BACKGROUND LEDs (light emitting diodes) are being deployed in controlled environment crop production systems to boost crop growth, manipulate pest behavior, improve performance of natural ...

The spider mite saga: quest for biorational management strategies [PDF]
The losses that growers have to absorb due to spider mites can be very discouraging. In spite of the use of acaricides which has understandably been short-term, the loss incurred in the Cameron Highlands ranged between 10-50% annually. The spider mite is

Spider mites (Tetranychidae sp.) are widely occurring arthropod pests on cultivated plants. Feeding by the two-spotted spider mite T. urticae, a generalist herbivore, induces a defense response in plants that mainly depends on the phytohormones jasmonic ...

Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Some Tetranychoid Mites of Michigan [PDF]
Excerpt: Tetranychoid mites are plant feeders, and many of them are of considerable economic importance. Prior to the present study, only seven species of these mites were known from Michigan; Oligonychus ilicis (McGregor) (McGregor, 1931); Tertranychus ...

The continuing significance of chiral agrochemicals
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.

A guide to the spider mites of cotton
Spider mites are increasingly serious pests of cotton and forage crops. Because the acaricides now being developed are often highly selective among species, entomologists concerned with the control of these pests need to know the particular species they are dealing with. This report has been prepared to aid them.
