RESEARCH AREAS OF SPECIALIZATION:
Primary
area of research is biology, ecology, and management of rice
insect pests. Primary pests are the rice stink bug and the rice
water weevil. Current research is in testing insecticides for
control of the rice water weevil, grape colaspis, and stalk
borer in different production systems. In support of the rice
breeding program rice lines are evaluated annually for susceptibility
to discolored kernels, especially discolorations by rice stink
bug damage. Also, research has begun into the ecology of the
rice stalk borer and grape colaspis, and injury potential of
aphids and armyworms on rice.
GOALS
AND RESEARCH FOCUS:
Biology
and Management of Insect Pests of Rice (Project No. 1672) has
a primary goal to provide rice growers with information on options
for the management of rice insect pests. Research objectives
include identifying cultural practices that may reduce yield
losses by the rice water weevil and rice stalk borer, biological
control agents of the rice stink bug, refining treatment thresholds
for rice stink bug and rice water weevil, and sampling procedures
for rice insect pests.
