Imidacloprid can be found in the trunk, the branches, the twigs, the leaves, the leaflets, and the seeds. Many trees are wind pollinated. But others such as fruit trees, linden, catalpa, and black locust trees are bee and wind pollinated and imidacloprid would likely be found in the flowers in small quantities.
Anemophily or wind pollination is a form of pollination whereby pollen is distributed by wind. [1] Almost all gymnosperms are anemophilous, as are many plants in the order Poales , including grasses , sedges , and rushes . [ 1 ]
Polylepis is a genus comprising 28 recognised shrub and tree species, [1] that are endemic to the mid- and high-elevation regions of the tropical Andes. [2] This group is unique in the rose family in that it is predominantly wind-pollinated. They are usually gnarled in shape, but in certain areas some trees are 15–20 m tall and have 2 m-thick ...
Wind pollination is the reproductive strategy adopted by the grasses, sedges, rushes and catkin-bearing plants. Other flowering plants are mostly pollinated by insects (or birds or bats), which seems to be the primitive state, and some plants have secondarily developed wind pollination.
Trees that are cross-pollinated or pollinated via an insect pollinator produce more fruit than trees with flowers that just self-pollinate. [1] In fruit trees, bees are an essential part of the pollination process for the formation of fruit. [2] Pollination of fruit trees around the world has been highly studied for hundreds of years. [1] Much ...

Ash flowers are wind-pollinated and lack petals and sepals. Structurally, the flowers may be bisexual, consisting of two stamens and an ovary, or may be male (staminate), lacking a functional ovary, or female (carpellate), lacking functional stamens. Different forms may occur on the same tree, or on different trees. [8]
Flowers of wind-pollinated plants tend to lack petals and or sepals; typically large amounts of pollen are produced and pollination often occurs early in the growing season before leaves can interfere with the dispersal of the pollen. Many trees and all grasses and sedges are wind-pollinated.
