Many parasites are satisfied with just living off of their hosts, while others decide their hosts…, It's not clear why the parasitoid wasps have an aversion to citrus, but the researchers think the fruits may be physically unsuitable to the wasps. Psyllids are also carriers of the bacterium that causes Huanglongbing (HLB) disease, also known as citrus greening disease, spreading the disease to healthy citrus plants. The fruit flies lay their eggs in the fruits and vegetables. But when given the choice, these annoying pests actually prefer citrus like oranges, limes, and lemons. This is due to the larvae that live inside the fruits that make the fruit decays. Fruit flies can be detrimental when they infest citrus trees, as they are not readily noticeable and can reduce fruit to mush. The genus includes approximately 500 species. By looking at the flies' neurons under the influence of limonene, the scientists found that a single class of olfactory sensory neurons is responsible for the insects' ability to detect terpene. Attractant or trapping substance is put on twisted cotton about the size of thumb and then tied with a small wire such that it is hang in the middle of the tube traps. Within the area, there could be found a small hole. This control is still an expensive control. Repeat this weekly or after rain while you have fruit or vegetables ripening and susceptible to attack from fruit fly.
