| identification and synthesis of male-produced sex pheromone components of the stink bugs chlorochroa ligata and chlorochroa uhleri. | the reproductive behaviors of the stink bugs chlorochroa ligata and c. uhleri were studied in the laboratory. adults of both species became sexually mature about 12-14 days after the final molt, and both sexes mated multiple times during their lifetimes. the mean duration of copulation was 54 +/- 24 min for virgin bugs and 46 +/- 33 min for experienced bugs for c. ligata and 78 +/- 55 min for field-collected c. uhleri of unknown mating status. male c. ligata were found to transfer a significant ... | 2001 | 11710612 |
| chemical and physical signals mediating conspecific and heterospecific aggregation behavior of first instar stink bugs. | we investigated cues that mediate the aggregation behavior of immature pentatomid bugs by using nymphs of six different pentatomid bug species (nezara viridula, acrosternum hilare, chlorochroa ligata, chlorochroa sayi, thyanta pallidovirens, and euschistus conspersus). when first instars of any two species were put together in a petri dish, they readily formed heterospecific aggregations similar to their natural conspecific aggregations. the chemical profiles of first and second instar nymphs of ... | 2004 | 15303327 |
| field trials of aggregation pheromones for the stink bugs chlorochroa uhleri and chlorochroa sayi (hemiptera: pentatomidae). | in field trials, adult chlorochroa uhleri (stål) (heteroptera: pentatomidae) of both sexes were caught in significant numbers in cylindrical screen traps baited with gray rubber septum lures loaded with the main component of the male-produced pheromone, methyl (e)-6-2,3-dihydrofarnesoate. addition of the two possible minor components of the pheromone, methyl (e)-5-2,6,10-trimethyl-5,9-undecadienoate and methyl (2e,6e)-farnesoate, did not affect attraction. combining the pheromone with different ... | 2010 | 21061959 |
