Planting dates were normal planting (NP) and late planting (10 days after normal planting) (LP), while insecticides comprised Apron star seed dressing (A) and without insecticide (WI). The combined analysis revealed that late planting combined with Apron star seed dressing (LPA) resulted in the highest yield (1223.7 Kg/ha). On the other hand, normal planting date without insecticide application (NPWI) gave the lowest yield (209.6 kg/ha) and the maximum yield loss (209.6%). The cost-benefit analysis showed that use of LPA gave by far better high net profit over control. Thus, LPA are recommended for haricot bean foliage beetle management in northeastern Ethiopia.","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2019-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2019/3728651","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47591218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The six most widespread species, Exaerete frontalis, E. smaragdina, E. dentata, E. trochanterica, E. lepeletieri, and Aglae caerulea, ranged from 12.5 to 28 mm in length (n = 522; 50 females; 472 males), and within species, some were 40-80% larger than others. The size of E. lepeletieri matches E. smaragdina and E. dentata, but not E. frontalis, which it was said to resemble. Female E. lepeletieri, here described from Amazonian Ecuador, has a range shown to also include French Guiana and Suriname. Female Aglae and Exaerete were larger than males. Statistically, female Exaerete tended toward larger individuals more than did males. Each species should parasitize Eulaema and Eufriesea that have comparable size and provisions; thus multiple hosts may cause parasite size variation. Unknown factors may promote host resource partitioning between sympatric parasites, which include up to six in Yasuní Biosphere Reserve, Ecuador, the richest known euglossine community. Scutellum and metafemur punctation, sculpture and the frontal knob of both sexes, and male mesotibial tuft and metafemur permit easy identification of the six common species and E. azteca. Existence of E. kimseyae in Panama is questionable, while E. dentata there is certainly rare. The female tibial scoop, a structure in both Aglae and Exaerete, with a proposed function in material transport, is discussed. No new phylogenetic interpretation is presented.","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2019-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2019/4602785","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48702611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hindwings are classified into three Typologies based on progressive veins reduction. This analysis follows a revision of the hindwing morphology in 291 extant and eight fossil genera. The distribution of different Typologies was analyzed in the two Clades: Formicoid and Poneroid. The results show a different distribution of Typologies, with a higher genera percentage of hindwings of Typology I in the Clade Poneroid. A further analysis, based on genetic affinities, was performed by dividing the Clades into Subclades, showing a constant presence of hindwings of Typology I in almost all the Subclades, albeit with a different percentage. The presence of hindwings of Typology I (hypothesized as more ancestral) in the Subclades, indicates the genera that could be morphologically more similar to their ancestral ones. This study represents the first revision of the ants’ hindwings, showing an overview of the distribution of different Typologies.","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2019-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2019/7929717","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48863579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results are not congruent with those of earlier work, and we did not conclude that honey bees must follow a dancer from behind in order to obtain the dance information.

Here, honeybees of five Apis species were collected from 12 provinces throughout Thailand. After DNA extraction, 28S rRNA nuclear (710 bp) and cytochrome b (cytb) mitochondrial (520 bp) gene fragments were sequenced. Homologous sequences (nucleotide identity of over 95%) were obtained from GeneBank using the BLASTn algorithm, aligned, and analysed by maximum likelihood and Bayesian inference phylogenetics. For 28S rRNA, a low genetic variation was detected within species (haplotype diversity ranging from 0.212 to 0.394), while 19 polymorphic sites were detected between species. Although the relative haplotype diversity was high, a low nucleotide divergence was found (0.7%), with migratory species. For cytb, the sequence divergence ranged from 0.24 to 3.88% within species and 7.35 to 13.07% between species. The divergence of cytb was higher than that of 28S rRNA. A. cerana showed two distinct clades between Southern Thailand and the other regions. Groups of A. cerana (Asian cavity-nesting), A. mellifera (European cavity-nesting), A. dorsata (giant open-nesting), and A. florea and A. andreniformis (dwarf bees) were defined in the 28S rRNA and cytb tree topologies.","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2019-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2019/5823219","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44849813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inequity is present in most of health indicators across social, economic, and demographic parameters. This study explores the existing health policy environment and current activities to further the progress towards Universal Health Coverage (UHC) and the challenges faced in these endeavors. This qualitative study involved document reviews (n=22) and key informant interviews (KII, n=15). Thematic analysis of texts (themes: activities around UHC, implementation barriers, suggestions) was done using the manual coding technique. We found that Bangladesh has a comprehensive set of policies for UHC, e.g., a health-financing strategy and staged recommendations for pooling of funds to create a national health insurance scheme and expand financial protection for health. Progress has been made in a number of areas including the roll out of the essential package of health services for all, expansion of access to primary health care services (support by donors), and the piloting of health insurance which has been piloted in three sub districts. Political commitment for these areas is strong. However, there are barriers pertaining to the larger policy level which includes a rigid public financing structure dating from the colonial era. While others pertain to the health sector's implementation shortfalls including issues of human resources, political interference, monitoring, and supervision, most key informants discussed demand-side barriers too, such as sociocultural disinclination, historical mistrust, and lack of empowerment. To overcome these, several policies have been recommended, e.g., redesigning the public finance structure, improving governance and regulatory mechanism, specifying code of conduct for service providers, introducing health-financing reform, and collaborating with different sectors. To address the implementation barriers, recommendations include improving service quality, strengthening overall health systems, improving health service management, and improving monitoring and supervision. Addressing demand-side barriers, such as patient education and community empowerment, is also needed. Research and advocacy are required to address crosscutting barriers such as the lack of common understanding of UHC.</p>","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":"2019 ","pages":"4954095"},"PeriodicalIF":1.1,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7691757/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38341189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its parental taxa are confirmed here to be M. banksi and M. pilosula. We suggest that its queens produce diploid female offspring by gynogenetic parthenogenesis, a process which requires interaction between unreduced maternal oocytes and allospecific sperm cells obtained by copulation with another related species. We propose that impaternata queens almost certainly mate for this purpose with males reared in impaternata nests from eggs laid by impaternata females. Because sex in ants is determined by haplodiploidy (males haploid, females diploid), we posit that these males would in fact not be technically conspecific with the females in whose reproductive systems they developed, since they would each carry the haploid genome of one or other of the hybridic parental species. They would therefore be individually identical karyologically to males of either M. banksi or M. pilosula and appropriately allospecific to M. impaternata. We postulate that, unlike all other known gynogens, M. impaternata would have no need to maintain parasitic affiliation or sympatry with free-living sperm-donor host species. Its queens are arguably able to produce the required allospecific males by accessing their own genomes. M. impaternata apparently originated by instantaneous speciation when individuals of its parental species first successfully hybridized.","PeriodicalId":20890,"journal":{"name":"Psyche: A Journal of Entomology","volume":" ","pages":""},"PeriodicalIF":1.1,"publicationDate":"2018-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1155/2018/2832690","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49053031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In light of this, knowing the venom’s chemical composition is of paramount importance in order to obtain information about the mechanisms of its components. Several bioactive molecules have already been identified in Hymenoptera venoms, i.e., proteins such as phospholipases, hyaluronidases, and proteinases, as well as peptides. Protein databases show that information on protein components of ant venoms has been recently growing exponentially. In this study, we have identified proteins from the venom ofEctatomma tuberculatumby means of 2D PAGE, followed by tandem nanochromatography with mass spectrometry. A total of 48 proteins were identified, of which 42 are involved in metabolic processes, transport, and structural support. Moreover, six of them show similarity with not yet characterized proteins. Nine proteins are related to the attack/defense or maintenance process of the colony (colony asepsis, conservation of venom constituents, venom diffusion on prey, paralysis of prey, alteration of homeostasis, and cellular toxicity).

The number of honeybees attacking the researchers’ protective gear within one minute of disturbance was recorded per colony and analyzed. Apis m. adansonii was found to be the most defensive. Variations in the agro-ecological zones, colony strength, and mean elevation were found to significantly influence the defensive behaviour of the honeybees. Honeybee colonies in the Mid North AEZ were the most defensive. The type of bee hive and vegetation cover did not have any influence on the defensive behaviour.
