“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.

    845. Understanding Desert Locust Behavior to Avoid Cannibalism During Molting ーAdvancing Eco-Friendly Pest Control Strategies

    The desert locust is an important pest that causes serious agricultural damage in Africa and Asia. Because there are many unknowns about its ecology in the field, inefficient and environmentally damaging pest control measures have to be used after an outbreak of desert locusts has occurred and the problem has become apparent. To address this problem, JIRCAS has been developing efficient pest control techniques based on desert locust ecology to reduce the damage to agriculture. In this issue, we present the results of research on the collective behavior of desert locust nymphs, in particular the avoidance of cannibalism during molting, which is essential for the establishment of pest control methods that lead to a reduction in the use of pesticides.

    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.
