Floral Insects Materials and Methods (306 words) We designed an experiment to determine the relationship between aphids and thrips in different development stages of Helianthus annus . In greek “ helios ” means sun and “ anthos means flower, thus Sunflower. In Helianthus bud stage ray flower is closed. As the bud stage ends, the flower stage is reached. The ray flower is opened surrounding the disk flowers. The stem and leaves lose their green color. The last stage of development is the seed stage when the disk florets mature into sunflower seeds, but are actually the fruit of the plant. Aphids are small, soft-body pear-shaped insects about 4-8mm long. There are hundreds of different species of aphids. Most aphids are commonly green and black, they may be white, red, etc. Aphids feed by sucking up plant juices. Thrips are tiny, slender insects with fringed wings . They can be identified by pale or black color as adults, it may be white or yellow as larvae. Males usually are smaller than females.
