We provide a general overview of features and technical specifications of an online, interactive tool for the identification of scale insects of concern to the U.S.A. ports-of-entry. Full lists of terminal taxa included in the keys (of which there are four), a list of features used in them, and a discussion of the structure of the tool are provided. We also briefly discuss the advantages of int...

In 1921, Scutellistacaerulea was imported and released in Nelson, New Zealand, for the biological control of pest scale insects. It was thought to have failed to establish, and is therefore currently considered to be absent from the New Zealand fauna. On 17 April 2013, a live specimen was captured in the wild in Auckland.

New cytogenetic data are reported for 17 species from 15 genera of the families Pseudococcidae, Eriococcidae, Kermesidae, and Coccidae. Twelve species and 6 genera (Peliococcopsis Borchsenius, 1948, Heterococcopsis Borchsenius, 1948, Heliococcus Šulc, 1912, Trabutina Marchal, 1904, Lecanopsis Targioni Tozzetti, 1868, and Anapulvinaria Borchsenius, 1952) were studied cytogenetically for the firs...

INTRODUCTION: As of 2001, it was estimated that approximately 50,000 nonindigenous species had been introduced into the United States (Pimentel et al. 2000). Some are beneficial, including food crops (e.g. corn, wheat), livestock (e.g. cattle, sheep), landscape enhancement (e.g. crape myrtles, boxwoods), or biological pest controls (e.g. host-specific biological control insects and pathogens). ...

pollination is the mechanical transfer of male pollen of a flower on the female stigma.this process has a fundamental role to survive the plants species.since this process is invisible ,its importance has been ignored.insufficient pollination can be harmful for the farmer instead of being useful.pollination can be done via some ways.the most important ways are done by insects and wind.pistachio...

background: aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. these insects have been, in some cases, well studied because they are vectors of several diseases. this is the first comprehensive faunistic study of aquatic insects from babol county. the results may provide basic data fo...

Almost all insects are equipped with a tracheal system, which appears to be sufficient for O2 supply even in phases of high metabolic activity. Therefore, with the exception of a few species dwelling in hypoxic habitats, specialized respiratory proteins had been considered unnecessary in insects. The recent discovery and apparently universal presence of intracellular hemoglobins in insects has ...

Maize (Zea mays Linnaeus, 1753) is economically the most important crop in Serbia, while European corn borer Ostrinia nubilalis (Hübner, 1796) (Lepidoptera: Crambidae) its significant pest of this crop. One potentially successful and environmentally friendly method for biological control based on usage wasps from genus Trichogramma Westwood, 1833 (Hymenoptera: Trichogrammatidae), which parasiti...

This paper deals with the semiotic meanings which are given both to the appearance and/or behavior of insect species according to the ethnoentomological knowledge of the inhabitants of the village of Pedra Branca, Bahia State, Brazil. Data were collected from February to May 2001 by performing open-ended, recorded interviews with nine men and twenty-five women, whose ages ranged from 19 to 82 y...
