Ovate gill golden turtle
Mainly distributed in South China and other places, a generation occurs once a year, in May 1 instar larvae appear to absorb soil organic matter, 6-7 months 2nd and 3rd instar larvae began to nibble on sugarcane underground rhizomes, affecting sugarcane growth.
Broad-toothed clawed gill turtle
A generation occurs every two years, and from late April to early May, adult insects appear in large numbers, hiding in the soil layer during the day, crawling out at dusk to feed on cane leaves, and appearing as a peak of harm.
South China's great black gill golden turtle
It occurs once a year, the overwintering adults begin to appear in mid-February, March and April is the peak period of excavation, with phototropism, and begin to move in the evening, nibbling on cane leaves to cause the leaves to wither and yellow, and larvae nibble on the cane head and rhizome.
Middle-beaked golden turtle
Distributed in Guangxi and other places, two generations occur every year, the first generation of adult insects bloom in April and June, the main generation is harmful, and the second generation of adult insects appears in August and September.
Sift gill turtles
It occurs once a year, mainly eating sugarcane leaves, and from early March to early April, adult insects begin to appear, which is harmful to sugarcane until November.
Coconut-studded rhinoceros turtle
A generation occurs once a year, the adult stage can reach several months or even half a year, the ability to fly is strong, generally choose sugarcane heart leaves as a pest, bite the heart leaves and leaves, suck the cane liquid, affect the growth of sugarcane.
Cane turtle control measures
Agricultural control
First, reasonable crop rotation: the implementation of water and drought rotation, or with cotton, sesame, rapeseed, hemp and other straight root crops rotation.
Second, deep ploughing ploughing: after the sugarcane harvest, the cane field is deeply ploughed, sunburned, and mechanically damaged larvae.
Third, irrigation of cane fields: at the peak of adult insect pests, water is diverted to soak the fields, and adult insects float on the surface of the water, and fishing and killing.
Pharmaceutical control

<col>
(1) Medication in the adult stage: (1) Root irrigation with medicine: At the peak of adult excavation, use 50% octyl thiophosphorus emulsion oil 7.5-11.25kg/mu to spray the base of cane seedlings with water. (2) Granule: 7 to 15 days before the adult insects are unearthed, 3% of the granules are culled 75 to 90kg/mu on the base of the cane seedlings, and then thinly covered with soil.
(2) Medication in the larval stage. In early to mid-September, when grubs are in the first instar larval stage, they are given in combination with pre-rain or immediately after rain.

(1) Adult stage: spray 48% Lesben emulsion 1500 times solution.
(2) Large soil cultivation period: 60kg/mu of chlorpyrifos granules are used to spread around the roots of sugarcane after soil cultivation.
(1) In the adult stage, the drug is sprayed with 50% octylthion emulsion 1000-1500 times liquid.
(2) At the larval stage, 3% furandan granules are used 60 kg/mu at the next planting stage, and the soil is covered after application to the roots. Fertilize again when cultivating soil.
