Many members of suborder Heteroptra harbor heritable symbiotic bacteria. Here we characterize the gut symbiotic bacterium in Graphosoma lineatum (Hemiptera: Pentatomidae) by using molecular phylogeny, real-time PCR analysis as well as light and electron microscopy observations. The microscopy observations revealed the presence of a large number of rod-shaped bacterial cells in the crypts. A ver...

Halyomorpha halys Stål, the brown marmorated stink bug (Hemiptera: Pentatomidae), is an invasive pest with established populations in Oregon. The generalist feeding habits of H. halys suggest it has the potential to be a pest of many specialty crops grown in Oregon, including hazelnuts, Corylus avellana L. The objectives of this study were to: 1) characterize the damage to developing hazelnut k...

abstract digestive enzyme inhibitors are proteinacious or nonproteinacious compounds which reduce an enzyme activity through attaching to its active site and/or its substrate. nowadays, plant enzyme inhibitors are of great importance because 1) these have considerable effects on insect digestive enzymes and as a result on their development; and 2) the transgenic plants expressing them are safe....

Bu çalışmada Çam Keseböceği [Thaumetopoea pityocampa (Den.&Schiff.)’nin (Lep.: Notodontidae)]’nin önemli yumurta parazitoiti olan Ooencyrtus pityocampae (Mercet) (Hym.: Encyrtidae)’nın Graphosoma lineatum (L.) (Het.: Pentatomidae) yumurtalarındaki etkinliği ve parazitlenme süresinin etkisi ele alınmış olup çalışmalar 25±1°C sıcaklık %65±5 neme ayarlı iklim odasında yürütülmüştür. Değişik sü...
