| impact of bt-corn mon88017 in comparison to three conventional lines on trigonotylus caelestialium (kirkaldy) (heteroptera: miridae) field densities. | in europe, bt-corn resistant against the european corn borer has until now been the only genetically modified plant to be grown commercially. with the advent of the western corn rootworm bt-corn varieties with resistance against coleoptera will become important. the cultivation of bt-plants may have negative impacts on non-target organisms, i.e. all species not explicitly targeted by a given bt-crop. one prominent non-target group in corn are the herbivorous plant bugs (heteroptera: miridae). th ... | 2009 | 18668336 |
| the effects of mating status and time since mating on female sex pheromone levels in the rice leaf bug, trigonotylus caelestialium. | although mating status affects future mating opportunities, the biochemical changes that occur in response to mating are not well understood. this study investigated the effects of mating status on the quantities of sex pheromone components found in whole-body extracts and volatile emissions of females of the rice leaf bug, trigonotylus caelestialium. when sampled at one of four time points within a 4-day postmating period, females that had copulated with a male had greater whole-body quantities ... | 2014 | 24419707 |
| attractants for rice leaf bug, trigonotylus caelestialium (kirkaldy), are emitted from flowering rice panicles. | volatiles were extracted from rice plants of various growth stages with solid-phase microextraction (spme) and analyzed by gas chromatography-mass spectrometry (gc-ms) to identify attractants that cause invasion of the rice leaf bug trigonotylus caelestialium (kirkaldy) into paddy fields. the composition of volatile blends produced by rice plants changed with rice development. in addition, volatile blend compositions differed between the panicles and the stems and leaves. the relative geranyl ac ... | 2010 | 20680414 |
| artificial selection for responsiveness to photoperiodic change alters the response to stationary photoperiods in maternal induction of egg diapause in the rice leaf bug trigonotylus caelestialium. | female adults of the rice leaf bug trigonotylus caelestialium (kirkaldy) (heteroptera: miridae) produce non-diapause eggs under long-day conditions, whereas they produce diapause eggs under short-day conditions. these egg-production modes change following a photoperiodic change from long-day to short-day conditions or vice versa, with individual variations in responsiveness shown in the time from the photoperiodic change to the mode change. strains of this insect with higher or lower responsiven ... | 2009 | 19482029 |
| identification of female sex pheromone of the rice leaf bug, trigonotylus caelestialium. | the female sex pheromone of the rice leaf bug, trigonotylus caelestialium, was analyzed by gc-ead and gc-ms. ten ead active compounds-n-hexyl n-hexanoate, (e)-2-hexenyl n-hexanoate, n-hexyl (e)-2-hexenoate, n-octyl n-butyrate, n-octyl n-hexanoate, (e)-2-octenyl n-hexanoate, n-pentyl n-hexanoate, n-hexyl n-butyrate, (e)-2-hexenyl n-butyrate, and n-hexyl (e)-2-butenoate-were detected in the ratio of 1,000:414-491:trace-5:5-11:55-71:50-63:trace-3:225:90:32 from female body extracts, and in the rati ... | 2001 | 11789951 |
