Abstract: The objective of this work was to evaluate the circadian feeding rhythm green-belly stink bug (Dichelops melacanthus) on corn (Zea mays), and correlate it with meteorological parameters. experiments were conducted in fields first (summer) second (fall) crop seasons, municipality Chapecó, state Santa Catarina, Brazil. Plants V3 V5 stages covered cages infested adults D. melacanthus. Af...
The quality of hosts for a parasitoid wasp may be influenced by attributes such as host size or species, with high successful development usually coincident larger offspring. This is not always the case: Scelionid Trissolcus basalis, oviposition in eggs Brown Marmorated Stink Bug, Halyomorpha halys, rather than normal host, Southern Green Nezara viridula, leads to lower offspring survival, but ...
Identifying and using native insect resistance genes is the core of integrated pest management. In this study, 10 experimental corn, Zea mays L., hybrids and 10 inbred lines were screened for resistance to major ear-feeding insects in the southeastern Coastal Plain region of the United States during 2004 and 2005. Ear-feeding insect damage was assessed at harvest by visual damage rating for the...
Plant sucking heteropteran bugs feed regularly on small amounts of K(+)-rich plant material, in contrast to their hematophagous relatives which imbibe large volumes of Na(+)-rich blood. It was anticipated that this would be reflected in the endocrine control of Malpighian tubule (MT) secretion. To explore this, neuroendocrine factors known to influence MT secretion were tested on MT of the pent...
We examined the salivary gland structure of the brown marmorated stink bug (Pentatomidae: Halyomorpha halys) and developed methods for independent collection of watery saliva and sheath saliva. This stink bug has become a serious invasive pest of agriculture in the United States and its saliva is largely responsible for the damage it causes. We determined by protein gel analysis and shotgun pro...
Some insects release scented compounds as a defense against predators that also exhibit antimicrobial activity. Trans-2-octenal and trans-2-decenal are the major alarm aldehydes responsible for the scent of Halyomorpha halys, the brown marmorated stink bug. Previous research has shown these aldehydes are antifungal and produce an antipredatory effect, but have never been tested for antibacteria...
