Notes on Italian Heptageniidae (Ephemeroptera). Rhithrogena Fiorii Grandi, 1953 and R
Aquatic Insects, Vol. 5 (1983), No. 2, pp. 69-76. Notes on Italian Heptageniidae (Ephemeroptera). Rhithrogena fiorii Grandi, 1953 and R. adrianae sp. n. by Carlo BELFIORE (Roma) ABSTRACT Rhithrogena adrianae, a new species related to R. diaphana Nav., is described from nymphs and male imagines collected in Central Italy. Taxonomic characters of nymphs and males of R. fiorii Grandi, whose nymphal stage was previously unknown, are also described and figured. Lectotype is designated for R. fiorii. The taxonomic status of Rhithrogena fiorii Grandi, 1953, described from winged stages only, was till now very uncertain. The type locality, near Bologna, is now altered by buildings and factories: R. fiorii has probably disappeared from that site. I have examined in Grandi's collection the specimens referred by her to R. fiorii, labelled: "Bologna, S. Luca, 16.III.1952 (l >, l < subim.), 20.III.1954 (l <, l > subim, l < subim.), 20.11.1955 (1 > subim.), 17.III.1955 (l <), .IV. 1955 (l >).I designate lectotype the male imago collected on 16.III. 1952. None of the spe- cimens is in a good state of preservation. Titillators are not truncate (Grandi, 1960: fig. 21,6 and pag. 91), but with few pointed lobes at the apex. During the first months of 1980 and 1981, in the river Mignone, near Rome, I collected and reared a hundred nymphs of Rhithrogena, from which I obtained some subimagines and two male imagines, easily referable to R. fiorii. I describe herein the taxonomic features of nymphs and males of this species. I also describe the male imago and nymph of a new species of Rhithrogena which lives in the same localities as R. -
Lecture 1 Principles of Applied Entomology the Field of Entomology May Be Divided Into 2 Major Aspects. 1. Fundamental Entomolog
Lecture 1 Principles of Applied Entomology The field of entomology may be divided into 2 major aspects. 1. Fundamental Entomology or General Entomology 2. Applied Entomology or Economic Entomology Fundamental Entomology deals with the basic or academic aspects of the Science of Entomology. It includes morphology, anatomy, physiology and taxonomy of the insects. In this case we study the subject for gaining knowledge on Entomology irrespective of whether it is useful or harmful. Applied Entomology or Economic Entomology deals with the usefulness of the Science of Entomology for the benefit of mankind. Applied entomology covers the study of insects which are either beneficial or harmful to human beings. It deals with the ways in which beneficial insects like predators, parasitoids, pollinators or productive insects like honey bees, silkworm and lac insect can be best exploited for our welfare. Applied entomology also studies the methods in which harmful insects or pests can be managed without causing significant damage or loss to us. In fundamental entomology insects are classified based on their structure into families and orders etc. in applied entomology insects can be classified based on their economic importance i.e. whether they are useful or harmful. Economic classification of insects Insects can be classified as follows based on their economic importance. This classification us according to TVR Ayyar. Insects of no economic importance:- There are many insects found in forests, and agricultural lands which neither cause harm nor benefit us. They are classified under this category. Human beings came into existence 1 million years ago. Insects which constitute 70-90% of all animals present in this world came into existence 250 - 500 million years ago. -

Life History and Production of Mayflies, Stoneflies, and Caddisflies (Ephemeroptera, Plecoptera, and Trichoptera) in a Spring-Fe
Color profile: Generic CMYK printer profile Composite Default screen 1083 Life history and production of mayflies, stoneflies, and caddisflies (Ephemeroptera, Plecoptera, and Trichoptera) in a spring-fed stream in Prince Edward Island, Canada: evidence for population asynchrony in spring habitats? Michelle Dobrin and Donna J. Giberson Abstract: We examined the life history and production of the Ephemeroptera, Plecoptera, and Trichoptera (EPT) commu- nity along a 500-m stretch of a hydrologically stable cold springbrook in Prince Edward Island during 1997 and 1998. Six mayfly species (Ephemeroptera), 6 stonefly species (Plecoptera), and 11 caddisfly species (Trichoptera) were collected from benthic and emergence samples from five sites in Balsam Hollow Brook. Eleven species were abundant enough for life-history and production analysis: Baetis tricaudatus, Cinygmula subaequalis, Epeorus (Iron) fragilis,andEpeorus (Iron) pleuralis (Ephemeroptera), Paracapnia angulata, Sweltsa naica, Leuctra ferruginea, Amphinemura nigritta,and Nemoura trispinosa (Plecoptera), and Parapsyche apicalis and Rhyacophila brunnea (Trichoptera). Life-cycle timing of EPT taxa in Balsam Hollow Brook was generally similar to other literature reports, but several species showed extended emergence periods when compared with other studies, suggesting a reduction in synchronization of life-cycle timing, pos- sibly as a result of the thermal patterns in the stream. Total EPT secondary production (June 1997 to May 1998) was 2.74–2.80 g·m–2·year–1 dry mass (size-frequency method). Mayflies were dominant, with a production rate of 2.2 g·m–2·year–1 dry mass, followed by caddisflies at 0.41 g·m–2·year–1 dry mass, and stoneflies at 0.19 g·m–2·year–1 dry mass. -

Silkworn Larvae after topical application of methoprene 585 Nota / Note DEVELOPMENT AND SILK PRODUCTION BY SILKWORM LARVAE AFTER TOPICAL APPLICATION OF METHOPRENE José Ednilson Miranda1*; Sérgio Antonio de Bortoli1; Roque Takahashi2 1 Depto. de Fitossanidade - UNESP/FCAV, Via de Acesso Prof. Paulo Donato Castellane, s/n. - CEP: 14884-900 - Jaboticabal, SP. 2 Depto. de Zootecnia - UNESP/FCAV. *Corresponding author <[email protected]> ABSTRACT: Juvenile hormone analogues have been tested as insect growth regulators in silkworm (Bombyx mori), seeking an increment of silk production. These chemical products, when applied in small or moderate rates, promote the extension of the last larval instar. To understand the physiologic consequences on silk production by the silkworm strain C115 x N108, the application of methoprene, a juvenile hormone analogue, was performed to evaluate its effects on larval development and silk production. Methoprene was topically applied 48h after the fourth larval ecdysis, on the dorsal integument of the 2nd thoracic segment of the insects, at seven rates between 0 and 20 ng a.i. Methoprene influenced positively the duration of the fifth instar and the weight gain of the insects. The application of 1ng methoprene resulted in the heaviest silkglands, cocoons, shell cocoons and pupae weights. Comparatively to the control, the increment on silk production (approximately 24%) by the use of 1ng methoprene was more accentuated than the corresponding negative effects on the cocooning rate (approximately 12%).

Submissions will not be considered unless this form is filled out completely. The proposer is expected to be familiar with the rules, recommendations, and procedures outlined in the “Use and Submission of Common Names” on the ESA website and with the discussion by A.B. Gurney, 1953, Journal of Economic Entomology 46:207-211. 1. Proposed new common name: European paper wasp 2. Previously approved common name (if any): None 3. Scientific name (genus, species, author): Polistes dominula (Christ) Order: Hymenoptera Family: Vespidae Supporting Information 4. Reasons supporting the need for the proposed common name: Since its introduction into North America (ca. 1968 New Jersey, ca. 1976 Boston area), this vespid has become widespread throughout the northern half of the United States and southern Canada. It some locations it has become the dominant Polistes species and a very visible insect in yards and gardens. 5. Stage or characteristic to which the proposed common name refers: “Paper wasp” refers to its habit of constructing a multi-celled umbrella-form nest. This is typical of Polistes spp., including those currently recognized as “paper wasps” in the ESA Common Names listing (e.g., Polistes aurifer/golden paper wasp, Polistes olivaceous/Macao paper wasp). This insect is native to Europe and a recent colonizer of North America. -
