Most of the studies on impact insecticides have always used acute toxicity with an indicator death, whereas lethal effect cannot fully determine insecticide insects. Overall, sublethal dose/concentration can cause biological effects, disrupt egg number, laying period, larva and pupal weight, development life span fertility rate, in addition to influencing feeding behavior, spawning locomotor sy...

flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

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...

UNLABELLED We have developed MEIMAN, a unique database on medicinal and edible insects of Manipur which comprises 51 insects species collected through extensive survey and questionnaire for two years. MEIMAN provides integrated access to insect species thorough sophisticated web interface which has following capabilities a) Graphical interface of seasonality, b) Method of preparation, c) Form o...

An experiment was designed to test the effects of metalized UV reflective silver plastic mulch on insect populations on a tomato crop as compared to the standard black plastic mulch. Yellow sticky cards, replaced weekly from June 8 to July 12, were used to collect flying insects, which were counted and classified. The total number of insects, and insects in the Thysanoptera, Homoptera, Aphidida...

abstract since amphibians feeds on insects, they have crucial role in controlling the population of pests in various ecosystems. although their importance is clear, but systematics and biodiversity of them has been poorly studied. the aim of this research, conducted in 2014, is to identify amphibians of talesh township and their biological roles in pest control. sampling procedure has been done...

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...

The heat shock proteins (Hsps) that are abundantly expressed in insects are important modulators of insect survival. The expression of different Hsp genes are induced and modulated in insects in response to environmental inputs including abiotic stresses such as heat shock, ultraviolet radiation, chemical pesticides, as well as biotic stresses such as viruses, bacteria, fungi and other insects....
