The Potency of Enthomopathogenic Nematode Isolated from Longicorn Borer in Controlling Squamura Celebensis (Lepidoptera: Cossidae) on cocoa

Squamura celebensis Roepke is one of the most important insect pests in Cocoa, Sulawesi Province, Indonesia. Such insects destroy mats and bark, and damage can significantly reduce cocoa productivity. Experiments were conducted at the Luwu regency farm and the effects of nematode treatment isolated from cocoa long horn mites on the inhibition of the development of Drosophila and the killing of the above pests were tested. This treatment was carried out by spraying 1000 nematodes in a piece having a length of 1 to 5 cm, a length of 6 to 10 cm, and a length of 11 to 15 cm.

The size of the beetle is 15 to 50 mm, which is commonly seen in the summer. They have a strong jaw and are often confused with quarantine pests in European Borer, Western Australia. However, European houses are small for adults, 8-25 mm, and shorter antennas. They hide in evacuation centers during the day and go out for food at night. Shelters can change from connected adjacent leaves or broken leaves to large solid structures such as bags or mobile homes. Box-shaped moths, bag moths, box moths, bag insects and leaf rollers belong to these groups. In Western Australia, reticular moth is a common pest of thiophenone and leucovorin. Symptoms are brown leaves and signs around leaf branches and ribbon leaves.

Suction cup preparation (peeling) is done in the field of collecting plant materials. This is to prevent new fields from being contaminated by nematodes and nematode infected bulbs. The prepared bulbs are transported to their destinations, where they are dried for several days (not under the sun). Bulb flaking delays the occurrence of nematode invasion while decreasing pseudostem decreases the volume and improves the early growth of freshly planted suckers. The peeling process seems to be cassava. A healthy bulb that has just been peeled should look white, but bulbs infected with aphids and nematodes show brown and black spots and must be removed until only white tissue remains

Plant parasitic nematodes can attack the roots, stems, leaves and flowers of plants. All plant parasitic nematodes have penetrating mouthpieces called probes. The presence of probes is an important diagnostic marker distinguishing plant parasitic nematodes from all other types of nematodes. Bacterial nematode Caenorhabditis elegans is one of the most obvious animals on earth. It is the first animal whose genome has been completely sequenced. The study of the nematode Caenorhabditis elegans has brought many new insights into the development of animals, neurobiology, behavior.
