Insect Pests of Rice in Laos [PDF]
PANS, 1978 Abstract The insect species feeding on rice in Laos were investigated during 1973–75. Populations were usually small but the most common species were Patanga succincta (L.), Leptocorisa spp. and Nezara viridula (L.) on the upland rice; Oxya and Euscyrtus spp. in the seedbeds and Chilo polychrysus (Meyr.), C. suppressalis Wlk. and Sesamia inferens (Wlk.)

Biological control of rice insect pests in China
Biological Control, 2013Abstract Rice is one of the most important food crops in the world. China has the second largest area of the rice growing in the world and the highest yield of rice produced. Infestation by insect pests, especially rice planthoppers, stem borers and leaf folders, is always a serious challenge to rice production in China.

Rice insect pests and their management
2017The rice plant is an ideal host for many insect species. All of the plant parts are vulnerable to insect-feeding from the time of sowing till harvest. There are over 800 insect species damaging rice in one way or another, although the majority of them do very little damage. In tropical Asia only about 20 species are of major importance.

Rice is the most important food for mankind. Annual world rice production amounts to approximately 460 million tons grown on roughly 145 million ha (Norton and Way 1990). Over 90% of this area lies in Asia, while the remainder is divided among Latin America, Africa, Australia, Europe, and the United States (IRRI 1989). To keep pace with projected human

Ecology of Common Insect Pests of Rice
Annual Review of Entomology, 1968Rice, the staple diet of over half the world's population, is grown over about 124 million hectares and occupies almost one fifth of the total world area under cereals. Classified primarily as a tropical and subtropical crop, it is cultivated as far north as 49° and as far south as 35°, and from sea level to altitudes of 3000 meters.

Stored-product insects damage agricultural commodities during storage, processing, and distribution. Postharvest losses are particularly costly. The production costs already invested in the crop place the value at its highest point, and the loss of relatively small percentages is financially significant.

ESTIMATION OF LOSSES DUE TO INSECT PESTS OF RICE
Madras Agricultural Journal, 1987Field experiments conducted at Tamil Nadu Rice Research Institute, Aduthurai to develop a better pest management programme to brown planthopper (BPH). green leaf) hopper (GLH) and stemberer (SB) revealed that the variety ADT 31 recorded lower population of BPH and very low SB incidence during kuruval season. During thaladi, BPH population and SB damage

Genetic Engineering of Rice for Resistance to Insect Pests
2020For human being, rice is an important crop both as a source of food and income. As the world population is expected to increase to 9.2 billion by 2050, there is a dare need to increase global food production to overcome the demand of world population. But unfortunately, there are a number of abiotic and biotic factors affecting rice production.
