| seasonal parasitism and host specificity of trissolcus japonicus in northern china. | the brown marmorated stink bug, halyomorpha halys (stål), native to china, japan, and korea, has emerged as a harmful invasive pest of a variety of crops in north america and europe. the asian egg parasitoid trissolcus japonicus has been identified as the most promising agent for classical biological control of invasive h. halys populations. a 4-year study evaluated the fundamental and ecological host ranges of t. japonicus as well as its phenology and impact on h. halys populations in fruit orc ... | 2017 | 28824354 |
| structural and ultrastructural features of the malpighian tubules of dolycoris baccarum (linnaeus 1758), (heteroptera: pentatomidae). | the morphology and ultrastructure of the malpighian tubules of dolycoris baccarum were analyzed by scanning (sem) and transmission (tem) electron microscopy in order to determine their functional organization. the malpighian tubules are compared with similar structures of other insects based on cell structure and functional organization. the malpighian tubules of d. baccarum extend from the midgut-hindgut region of the digestive tract. the malpighian tubules are divided into two regions: the pro ... | 2017 | 27859898 |
| the complete mitochondrial genome of dolycoris baccarum (insecta: hemiptera: pentatomidae). | the complete mitochondrial genome (mitogenome) of dolycoris baccarum (hemiptera: pentatomidae) has been sequenced and annotated in this study. this mitogenome is 16,549 bp in length with an a+t content of 73.4%, and contains the typical 37 genes that are arranged in the same order as that of the putative ancestor of hexapods. all protein-coding genes (pcgs) start with atn codons except for cox1 that uses ttg as the initial codon. eleven pcgs stop with termination codon taa, and cox1 and cox2 hav ... | 2013 | 23391217 |
| antibacterial activity of 4-oxo-(e)-2-hexenal from adults and nymphs of the heteropteran, dolycoris baccarum (heteroptera: pentatomidae). | we identified 4-oxo-(e)-2-hexenal (4-ohe) as a common component of the secretion from both dolycoris baccarum nymphs (66.5 ± 34.7 µg/bug) and adults (87.4 ± 48.0 µg/bug) by gc/ms. we also found that this compound inhibited the growth of bacteria starting at 10 µg. the stronger antibacterial activity of 4-ohe than that of (e)-2-hexenal and (e)-2-octenal might be explained by the reactivity of α,β-unsaturated aldehydes with nucleophilic molecules. | 2012 | 23047086 |
| the morphology and histology of the male reproductive system in dolycoris baccarum linnaeus 1758 (heteroptera: pentatomidae)--light and scanning electron micoscope studies. | the male reproductive system of dolycoris baccarum (linnaeus 1758) is studied morphologically and histologically using both light and scanning electron microscopes (sem). the reproductive system of the male d. baccarum consists of a pair of testis, a pair of vas deferens, a pair of seminal vesicles, accessory glands (mesadenia, ectadenia), a bulbus ejaculatorius, a pair of ectodermal sacs, and a ductus ejaculatorius. the number of testicular follicles varies from four to six. the testicular foll ... | 2013 | 22726265 |
