Golden apple snails damage plants by grating plant tissue and eating it, causing seeds to be lost in the crop. The former pieces of leaves and stems that he attacked look floating. The critical time for controlling golden snails is 10 days after transplanting or 21 days after sowing (wet seeds). After that, the plant growth rate is greater than the rate of damage by golden snails.
In the event of an invasion of golden snails, rice fields need to be drained immediately because golden snails are like places that are flooded with water. If farmers plant with the transplant system, 15 days after transplanting, the fields need to be dried and then soaked alternately (flash flood = intermittent irrigation).
If rice is planted by direct sowing, for 21 days after sowing, the fields need to be dried and then flooded again in turn. In addition, it is necessary to make a pond trough in and around the rice fields before planting, both during the rainy and dry seasons. This is so that when drying, the golden snail will go to the pond trough so that it is easier to take the golden snail and control it.
The golden snail is one of the important pests that attack young rice, especially in rice fields planted with the table system. Its presence in the field is indicated by the presence of pink eggs and golden snails of various sizes and colors. The golden snail can be controlled through:

In rice ecosystems in Asia, there are two species of Black Bug, namely the Malayan Black Bug, Scotinophara (=Podops) coarctata and the Japanese Black Bug Scotinophara (=Podops) lurida. Many more species are similar to the two bedbugs but rarely reach abundance amount. These two bedbugs are often in abundance, and because control with pesticides is difficult, these pests often cause heavy losses. During the day, old black-and-brown bedbugs cluster together at the base of the rice stalks, right at the edge of a puddle of water.
