1. Pea aphids (Acyrthosiphon pisum Harris; Hemiptera: Aphididae) exhibit transgenerational wing polyphenism, in which unwinged females produce genetically identical winged offspring in response to environmental cues such as overcrowding and predation risk that indicate poor habitat quality. 2. Laboratory experiments were carried out to explore the intensity of the wing polyphenic response of pe...

A new species of the genus Pseudaspidimerus Kapur, 1948 (Coleoptera: Coccinellidae), Pseudaspidimerus palatus Huo & Wang, sp. n. from the Malay Peninsula is described with illustrations and a distribution map. The genus Pseudaspidimerus is recorded for the first time from Malaysia and Singapore.

The multicolored Asian lady beetle, Harmonia axyridis (Pallas), native to Asia, has recently been detected in South America after successfully invading North America and Europe. This coccinellid is a voracious predator; therefore, it is popular and effective in biological control. Unfortunately, H. axyridis also has associated adverse impacts (i.e., as a household pest, pest of fruit production...

The subgenus Orthoscymnus Canepari, 1997 of Scymnus Kugelann, 1794 is herein revised. Seven species of the Orthoscymnus fauna are recognized, of which four species, Scymnus (Orthoscymnus) jilongicus sp. n., Scymnus (Orthoscymnus) paradoxus sp. n., Scymnus (Orthoscymnus) crispatus sp. n. and Scymnus (Orthoscymnus) duomaculatus sp. n., are described as new to science. Scymnus (Orthoscymnus) rhodo...

During the field research conducted in 2018-2020, species composition of coccinellidae selected area was determined. We had a comparative analysis accounting for quantitative and taxonomic over years study. studied biology ecology each species, including trophic relationships species. The main food groups been identified depending on objects, biotope distribution, their ecological identified.Th...

Coccinellids have been widely used in biological control for over a century, and the methods for using these predators have remained virtually unchanged. The causes for the relatively low rates of establishment of coccinellids in importation biological control have not been examined for most species. Augmentative releases of several coccinellid species are well documented and effective; however...

Myrrha octodecimguttata (Linnaeus, 1758) and Epuraea ocularis Fairmaire, 1849 are recorded from Israel for the first time, both species collected in Shoham Forest.

Three sequential studies were conducted on the interacting effects of exposure to low (5°C) temperature for 0, 7, 28, 56, or 84 d followed by incubation at 10, 15, or 20°C on the egg diapause of Scymnus (Neopullus) camptodromus Yu and Liu (Coleoptera: Coccinellidae). This beetle was imported from China as a potential biological control agent for hemlock woolly adelgid, Adelges tsugae (Annand) ...
