“Transboundary pest management”
Development of environment-friendly management system against transboundary plant pests based on ecological characteristics

Related Research Program



The damage caused by transboundary insect pests is increasing due to the expansion of the overwintering potential area caused by global warming and the acceleration of migration and dispersal caused by social globalization. From Africa to Asia, damage to a variety of crops caused by the desert locust is becoming a problem. In addition to the rice planthopper, which has been an important transboundary pest for a long time, in recent years, the fall armyworm has invaded and caused significant damage in Asia. In order to prevent the spread of transboundary pests, it is necessary for developed countries to take the lead in developing management technologies that have a low environmental impact, and to build a cooperative system that includes developing regions.


In collaboration with international organizations, we will develop efficient and environment- friendly management system  based on the ecology of transboundary pests such as desert locust, rice planthopper, and fall armyworm in countries where these pests are endemic. In addition, we will present an economic evaluation model that will serve as a guideline for the development of efficient integrated pest management technologies when new transboundary pest problems emerge.

Saitama Prefectural Kumagaya High School Students Visit JIRCAS

A group of 38 first year senior high school students and two teachers from Saitama Prefectural Kumagaya High School visited JIRCAS on November 26 (Friday), 2021 through the "Tsukuba Science Tour". This was the second visit from the school, following last November. As a safety measure against COVID-19, the students were divided into two groups, one in the morning and the other in the afternoon, for introduction of JIRCAS research activities (indoor lecture).

    401. Elucidating the Unique Reproductive Behavior of Desert Locust Leads to Reduction in Use of Pesticides

    Desert locusts are found in semi-arid regions from West Africa to India, where they often cause serious agricultural damage. JIRCAS is conducting research to develop efficient control technologies based on the ecology of desert locust. In this article, we introduce our research on the reproductive behavior of the desert locusts, which can lead to environment-friendly pest control that does not require the use of pesticides more than necessary.
