Black Rice Bug
Black rice bug or mostly known as ‘’ itim na atangya ‘’ appears commonly during rainy seasons yet they are also seen during summer and when irrigation starts. An adult female bug lays their eggs in clusters, each containing 29-34 eggs, egg incubation of RBB is 3 to 7 days. It lives from 3 to 7 months. The female lays about 200 eggs during her lifetime. Large populations of this pests are more common on lowland rice, rain fed fields and continuously irrigated ones, because the eggs only survives when near the water source. During dry conditions, the female bug deposits its eggs on the leaves and stem. Eggs are also laid in cracks on the soil and on roots. These bugs belong to the Pentatomidae and under in the Hemiptera order which tells that these bugs are truly pests to our crops and plants. According to the International Rice Research Institute and the International Centre of Insect Physiology and Ecology, there are three or four overlapping generations of these pests in a year. The first generation and part of the second generation occur on the first crop; the remainder of the second, the third, and part of the fourth generation occurs on the second crop. There are two overlapping generations in aestivation at each period between crops. At aestivation sites, fourth and fifth in star nymphs and adults are most commonly found.
In Trece Martires, Cavite, agriculturists are trying to control the rice black bug using several methods still they are unable to kill these pests. According to provincial agriculturist Engineer Mario C. Silan, these pestering bugs have swarmed and virtually dried up plantations in at least eight towns and one city of the province. Silan also stated that the towns of Naic, Maragondon, Carmona, General Trias, Imus, Tanza, Kawit, Ternate and Dasmariñas are already infested by these bugs. Prior to this, in a bid to get rid of the plague, Naic Mayor Edwina Mendoza
