| two pests overlap: drosophila suzukii (diptera: drosophilidae) use of fruit exposed to halyomorpha halys (hemiptera: pentatomidae). | drosophila suzukii (matsumura) (diptera: drosophilidae) and brown marmorated stink bug, halyomorpha halys (stål) (hemiptera: pentatomidae), are global economic pests that may co-occur on small fruits. we investigated whether fruit recently exposed to h. halys affected subsequent host use by d. suzukii. laboratory no-choice and choice tests presented d. suzukii with h. halys-fed and unfed raspberries and blueberries immediately or 3 d after h. halys feeding. resulting d. suzukii eggs, or larvae a ... | 0 | 28575326 |
| evaluation of mature soybean pods as a food source for two pod-sucking bugs, riptortus pedestris (hemiptera: alydidae) and halyomorpha halys (hemiptera: pentatomidae). | riptortus pedestris (fabricius) and halyomorpha halys (stål) cause injury to soybeans by piercing and sucking pods and seeds. growers believe that new damage decreases near to harvest despite the occurrence of these bugs at that time. as this question has never been assessed, we evaluated two diets: a) mature soybean pods (dried shell + dried soybean seeds) and b) dried soybean seeds for the two bugs by assessing their biological, behavioral, and morphological attributes on each diet in laborato ... | 0 | 28430798 |
