Recent populations of the red sunflower seed weevil, Smicronyx fulvus LeConte (Coleoptera: Curculionidae), have been inconsistent or declining, particularly in North Dakota. Consequently, research on weevil biology, including development of resistant germplasm, has been limited. To determine whether cold storage of diapausing larvae could be improved, nonconstant temperature treatments (fluctua...

Biological invasions with known histories are rare, especially in the sea, and empirical studies of the genetic consequences are even rarer. Fifty-five years ago, the state of Hawai'i began a remarkable, if unintentional, 'experiment' with the introduction of three reef fishes, Lutjanus fulvus, Cephalopholis argus and Lutjanus kasmira. All have since expanded from the initial introduction of 22...

The Kresna Gorge attracts significant scientific ornithological interest as it is situated along one of the primary bird migration routes – Via Aristotelis. In 2010, a process reintroducing Griffon Vulture (Gyps fulvus) began in area, which can now be deemed success. However, there are still various anthropogenic factors that have negative impact on population’s resilience. purpose this study t...

Effective mitigation of the risks posed by environmental contaminants for ecosystem integrity and human health requires knowing their sources and spatio-temporal distribution. We analysed the exposure to lead (Pb) in griffon vulture Gyps fulvus-an apex species valuable as biomonitoring sentinel. We determined vultures' lead exposure and its main sources by combining isotope signatures and model...

Between 1990 and 1995, the USDA/APHIS National Biological Control Laboratory in Niles, MI, Texas A&M University, and the University of Massachusetts conducted a biological control introduction program against the Asian diaspidid scale insect Unaspis euonymi (Comstock), a pest of woody landscape plants. Two species of predators ( Chilocorus kuwanae Silvestri, Coleop.: Coccinellidae and Cybocepha...

We have studied the relationship of bruchids and their legume hosts by extensive field sampling throughout Hungary over 17 years and by rearing the beetles from the samples in the laboratory. The value of the system lies in the accuracy of host affiliations. A total of 138 species and subspecies of plants were sampled, representing approximately 87% of the Leguminosae in Hungary. Only 51 legume...

The following two new species of Culicoides from the Argentinean Yungas are described, illustrated and placed to subgenus or species group and compared with related congeners: Culicoides calchaqui Spinelli & Veggiani Aybar and Culicoides willinki Spinelli & Veggiani Aybar. Culicoides daedaloides Wirth & Blanton is recorded for the first time for Argentina and Culicoides pseudoheliconiae Felippe...

Three new species of Coccobius Ratzeburg (Hymenoptera: Aphelinidae) are described from China, Coccobius bimaculatus Wang, Huang & Polaszek sp. nov., Coccobius jinshanensis Wang, Huang & Polaszek sp. nov. and Coccobius leptocerus Wang, Huang & Polaszek sp. nov. Coccobius abdominis Huang 1994 and Coccobius furviflagellatus Huang 1994, originally described in Chinese, are redescribed in English an...
