Rice Stink Bug

Biological control of Oebalus insularis eggs is considered an important strategy in the control of this rice “stink bug”. Effects of essential oils (EOs) from Piper jacquemontianum Kunth and Piper marginatum Jacq. (Piperaceae) on the viability of parasitized and unparasitized eggs by Telenomus podisi, in concentrations of 0.5 to 2.0%, were evaluated. EOs from both species at a concentration of 2% affected the development of embryons of O. insularis as well as of T. podisi after 24 and 48h of their administration. In both species, P. jacquemontanium and P. marginatum LC50, 24 h before the application of treatments on eggs of O. insularis was 3.835 y 3.037, respectively. LC50 after 48 h of treatment with EOs showed contrasting results which varied from 2.207 and 1.811. for P. jacquemontianum and P. marginatum, respectively. LC50 calculated before 24 h in parasitized eggs of O. insularis by T. podisi, was 3.037 and 2.171 for P. jacquemontianum y P. marginatum, respectively, while after 48h of treatment it was 1.166 y 1.935, respectively. Absorption of the EO components by the unparasitized and parasitized eggs of O. insularis by T. podisi was higher after 48 h of exposition. This is due to the longer exposure time, which allows higher penetration of the EOs into the interior of insect eggs by microscopic pores and micropyle.

Abstract The stages of rice, Oryza sativa L. (Poales: Poaceae), grain maturity that are most susceptible to rice stink bug, Oebalus pugnax (F.), damage have been identified; however, the stage at which they are no longer capable of causing appreciable damage during grain maturity is unclear. The objective of this study was to determine the susceptibility of rice to rice stink bug feeding at different levels of grain maturity and determine an insecticide termination timing. Rice stink bug damage was examined using five levels of grain maturity described as percent of kernels reaching mature straw coloration referred to as hard dough (20, 40, 60, 80, and 100%) across a range of infestation levels using single panicle sleeve cages and large cages. Hybrid and conventional cultivar rice panicles at 20, 40, and 60% hard dough were found to be susceptible to indirect yield loss, as two rice stink bugs per panicle resulted in over 7% peck. In large cage trials, 25 rice stink bugs caused 0.7–1% peck to hybrid and conventional rice plots at 20% hard dough. Much less damage was observed once rice reached 60% hard dough, where peck averages only reached 0.4%. Decreased damage at 60% hard dough was validated using uncaged trials where 0.4% additional peck was observed in unsprayed plots. These data indicate that rice in the early stages of hard dough is susceptible to large levels of indirect yield loss, but unless significant densities of rice stink bug are present at 60% hard dough, no more sampling or applications are necessary.
