Hi @agrovision welcome to my blog! I would like to know how spiders of the genus Teminius affect such crops. Weaver spiders such as those of the family Theridiidae or Araneidae hinder certain agricultural practices with their webs on the aerial parts of plants, which can sometimes damage the aesthetics or if the web is too much it can hinder the photosynthetic process. On the other hand, arachnids of the family Tetranychidae are considered potential pests, as these mites are phytophagous, but I have never heard or seen anything negative about spiders of the genus Teminius in crops, your comment is interesting for this reason. Thanks so much for stopping by and commenting, hope you are well!

The species of the genus Teminius, what they do is to obstruct the epidermal surface of the leaves, this indirectly affects the processes of photosynthesis and photorespiration, therefore, the effect that has been evaluated is the percentage that decreases the photosynthetic capacity, so far field trials have been reported in orange and rice crops.
These assessments are interesting. I would say that they are still specimens of low negative impact on agriculture, especially because they are solitary spiders, something contrary to what happens with some species of the Theridiidae family, which may have certain social behaviors by which they end up colonizing the plants of agroecosystems and wrap them in large webs. Thanks for commenting.
