Ophideres fullonica Linnaeus, also known as the small-toned nocturnal moth, the pseudo-herbaceous nocturnal moth, the Himetsu nocturnal moth, and the vantinophyllum noctuidae. It belongs to Lepidoptera, Noctiaceae.
【Host】Citrus, lychee, longan, mango, pear, persimmon, peach, grape and other fruit trees.
[Harmful] is the same as the mouth pot nocturnal moth.
【Morphological characteristics】Adult insects have a body length of 36 to 40 mm and a wingspan of about 106 mm; the cephalothorax is light purple-brown, the abdomen ventral surface is yellowish brown, and most of the back is yellow. The ovary is oblate spherical, with a rounded top and rounded ovations. The larvae have a variable body color, the head is dark purple or black, the body is yellowish brown or black, and the terminal larvae are 60 to 68 mm long, the anterior end is pointed, usually the first and second abdominal segments are curved in an ulnar-shaped shape, and the eighth abdominal segment is raised, connecting the seventh to tenth abdominal segments into a mountain. There are irregular macula on each segment; the first to eighth abdominal segments have irregular red spots, and the second and third abdominal segments each have an eye-shaped spot on the subverse, and the outer thorax and foot are yellowish brown, and the gastropods are reddish brown. Pupae are dark brown.
【Life Habits】Occurs 4 to 5 generations a year, with larvae and pupae overwintering in grass, stone crevices and soil gaps. Most of the larvae begin to pupate in late winter and early spring, but some larvae are still active for feeding when the air is warm. From the end of March to the beginning of April, the first generation of adult insects appeared and began to harm fruits such as peaches and plums, and the second generation of adult insects were harmful to lychees and longan. The generations of deciduous noctuidae overlap, with adults beginning to become citrus pests after mid-August and peaking from late August to early October.
【Control method】Refer to the control of the nocturnal moth with a bird's beak. (1) Avoid mixing varieties or multiple fruit trees at different maturity stages; eradicate the larval host plant wood self-defense, and at the same time eradicate weeds in and outside the park to reduce the resting place of adult insects; early maturing varieties in mid-August to early September fruit bagging or paper-wrapped fruit. (2) Red-eyed wasps are bred around July and released around citrus groves to parasitize nocturnal moth eggs. (3) Install frequency vibration insecticidal lamps or intelligent solar insecticides to trap adult insects. (4) Remove the host plants in the garden and the garden, and eliminate the larval food source. (5) Control of larvae and adult insects in the early stage of insect infestation. Agent optional: 80% dichlorvos emulsion 800 times liquid, etc.
