These days received a few fruit farmers consulted, golden autumn sugar orange is the ripening period, but the fruit drop is serious, can not find the cause, I watched the small video taken, determined that it is caused by orange small fruit fly. This is not an isolated case, many fruit farmers have reported this situation, orange small fruit fly may occur in local areas this year.
<h1 class="pgc-h-arrow-right" > it's too late to medicate</h1>
For the control of orange small fruit flies, fruit farmers are not of much use now, because orange small fruit flies do not stay in the fruit tree for too long, they run away after laying eggs on the fruit, and usually rarely stay in the orchard.
During the ripening period of citrus, try to use less medicine to avoid excessive fruit residues.
If there is already a fruit fallen orchard, it is necessary to pick up the fallen fruit in time, and then let the insect infested fruit soak in water or add lime to treat it, so as to avoid the orange fly pupae hiding in the soil.
<h1 class= "pgc-h-arrow-right" > all kinds of citrus need to be careful of orange small fruit flies</h1>
Orange small fruit fly for the harm of citrus, is also indiscriminate, whether it is golden autumn sugar orange, or orange, or tribute orange, may suffer from the scourge of orange small fruit fly, some farmers said that they have never seen this pest, do not take it lightly.
For the current control of orange small fruit fly, the farmer teacher recommends serial tracking of adhesion binder, which is different from the previous ordinary yellow gum adhesion, ordinary adhesion is mainly to add pheromones to lure male insects, and now the fruit has just tracked the adhesive, can kill both male and female.

Serial tracking of the adhesive, the main use of "population aggregation" (the results of dr. Research of the University of Agriculture for many years), that is, the use of orange small real fly "acquaintance relationship" to trap, figuratively speaking, that is: after a small real fly is stuck, it will send a "distress" signal, so its relatives and friends will also come after the servants, and eventually will be swept away!
