Zephyranthes pests and control methods

The harm of the zephyranthes moth

The liquid moth is the most common pest of Allium orchid and occurs sporadically every year. The insect mainly feeds on stems and leaves, which seriously affects the appearance of the Allium orchid and causes its growth to weaken, but it does not cause the Allium orchid to die. However, in severe cases, all the leaves on the above-ground part will be eaten, and the plant will not be able to grow unless it dies.

The occurrence pattern of the Allium zephyranthes

Noctuid infestations can occur 5 to 6 times a year. The adult insects will enter the soil with dead branches in late November to hibernate and re-hatch in the spring of the following year. Larvae generally like to live in groups to forage, and their feces will also pile up together.

During the hot summer, the larvae will feed in the morning and evening and hide during the day. The larvae are most harmful in August and September, so prevention should be done in advance.

Control methods of onion moth

In winter or early spring, replace the soil when repotting, or disinfect the soil to kill insect eggs.

When the larvae appear, spray the pesticide in time. Commonly used ones are Miman, Lesben, etc. Choose to spray in the morning or evening when the larvae are active, and the prevention and control effect is better.
