ABSTRACT. The black bug species Corimelaena harti (Hemiptera: Heteroptera: Thyreocoridae) was described over 100 years ago, yet practically no ecological information is known about the species. We newly report Galium concinnum (shining bedstraw) as a confirmed host plant and “mountain mint” as a second possible host plant. Further, we report this black bug species as a new state record for Ohio.

ABSTRACT. We report 12 new observations of parasitically-founded Vespula flavopilosa colonies. Of these, 4 nests were identified directly by having been found in the pre-emergence stage, whereby only the resident queen was seen foraging before the presence of the first workers. Seven nests were found in the early phases of worker production, wherein the queen and first workers were foraging simultaneously, or nests were observed containing workers of both the host V. maculifrons and parasite V. flavopilosa freely foraging together. A twelfth nest, collected later in the season, appeared to have been the result of a usurpation of a V. germanica nest, based on gray paper found in the central cores of the first three combs of the nest. This represents the first report of V. flavopilosa utilizing the introduced V. germanica as a host species. These observations cover a wide part of the species' range, and imply that V. flavopilosa is a frequent temporary social parasite. Furthermore, this behavior appears to be obligatory since an incipient nest founded unequivocally by a V. flavopilosa queen has not been recorded.

ABSTRACT. Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), is one of the most important insect pests of storage products. Considering the adverse effects of chemical pesticides, it is necessory to find substitute agents for managing insect pests, including P. interpuntella. Plant-derived essential oils have been introduced as suitable candidates to replace detrimental synthetic chemicals. Therefore, along with the toxicities of the essential oils of pistachio peel and basil leaves, their effects on the α-amylase enzymes and protein contents of 5th instar larvae of P. interpuntella larvae were evaluated in the current study. Concentrations of the pistachio and basil essential oils were regarded to be 50-150 and 60-400 µl.l within 24 and 48 h exposure times, respectively. The results showed that the considered times and concentrations had significant effects on P. interpuntella larvae (P<0.01). The mortality rates increased by enhancing their concentrations. LC50 were 178.14 and 89.34 µl.l and 49.79 and 31.28 µl.l after 24 and 48 h, respectively. The essential oils demonstrating 30.8 and 37.8% of inhibitions for the relative α-amylase enzyme activities in the treated 5th instar larvae were significantly different from those of the control group. The essential oils of pistachio peel and basil displayed promising potentials for the management of P interpunctella with especial fumigant toxicities capable of disrupting the protein content and α-amylase inhibitory activity.

ABSTRACT: Two Anopheles triannulatus genetic lineages were previously detected, differentially distributed at northwest (NW lineage) and southeast (SE lineage) Colombia. These lineages could differ in their biology and ability to transmit malaria. Although the lineages were molecularly defined using the 3' Cytochrome c oxidase subunit 1 (cox1 or COI) and the internal transcribed spacer 2-ITS2 sequences, a different cox1 region, the 5′ end, has been widely used for species identification in dipterans and may be used in differentiating these lineages. This study compared the variation between two cox1 gene regions, the 3' (Lunt) and 5' (Folmer) ends, in An. triannulatus from Colombia in order to evaluate their accuracy for identification at the lineage level. Results showed that the cox1 Folmer fragment would not facilitate detection of lineages in An. triannulatus, while cox1 Lunt allowed separation of specimens into the two perilously detected lineages, NW and SE.

ABSTRACT: The organization of ant communities can be affected by vegetation characteristics and by interspecific interactions. We evaluated the roles of vegetation complexity/heterogeneity and interspecific interactions on the organization of ant communities in two contrasting habitats. A total of 25 species of ants were collected in pitfall traps in the Cerrado (13 species) and in the Atlantic forest (22 species). Beta diversity (Dβ) was higher among Atlantic forest trees and the plant height positively affected the richness of ants. Greater Dβ in the Atlantic forest environment could be explained by the greater complexity of the vegetation in this environment. Co-occurrence analyses have shown that interspecific interactions are more important in shaping ant community organization in the Cerrado than in the Atlantic Forest. Low availability of resources can generate interspecific competition and competitive exclusion. Thus, the variation in resource availability could explain the results of the co-occurrence analyses. Finally, the importance of resource availability for the conservation of ant diversity is discussed.

The phlebotomine sand flies (Diptera: Psychodidae) are blood-feeding insects with a predominantly tropical distribution; however, some Nearctic species range north into Canada (Young and Perkins, 1984). Females feed on blood as a protein source prior to laying eggs and are vectors of a wide range of pathogens including viruses, bacteria, and protozoans to domestic and wild animals and humans (Ayala and Lee, 1970; Young and Perkins, 1984; Tesh, 1988; Caceres 1993). In the United States, several species of phlebotomine sand fly (Diptera: Psychodidae) have been incriminated or associated with transmission of vesicular stomatitis virus (Stallknech, 2000; Schmidtmann et al., 2002) and Rio Grande virus (Calisher et al., 1977).

ABSTRACT: The giant willow aphid (GWA), Tuberolachnus salignus (Gmelin) was reported for the first time from the cold arid region of Ladakh, India. The identification of GWA was done based on morphological and molecular characterization. The important morphological characters of GWA are grayish-golden color, covered with numerous fine hairs with a large dark brown tubercle in the center of the back. GWA is a serious pest of willow and poplar trees. There is a need to study the biology and host selection behavior of this pest to develop effective management strategies.
