Lady beetles (Coleoptera: Coccinellidae) as a biological control agent are a group of beetles with a considerable diversity and adaptation in different habitats. Among aphids, <em>Aphis punicae</em> Passerini (Hemiptera: Aphididae) is one of the most important pests of pomegranate orchards in Iran. This pest reduces plant vigor, facilitate the growth of mold on leaves, and consequently influences crop quality and yield. Study on the fauna of predatory ladybugs associated with pomegranate orchards was conducted that were feeding on <em>Aphis punicae</em> in the Najafabad region (Isfahan province, Iran). Twelve species of 8 genera were collected Sampled specimens were identified according to their morphological, male and female genitalia characters using identification keys. The identified species were as follow: <em>Adalia bipunctata</em> (Linnaeus, 1758), <em>Coccinella septempunctata</em> Linnaeus, 1758, <em>Coccinella undecimpunctata</em> Linnaeus, 1758, <em>Exochomus undulates</em> Weise, 1878, <em>Hippodamia variegate</em> (Goeze, 1777), <em>Hippodamia tredecimpunctata</em><em> (</em>Linnaeus, 1758), <em>Oenopia conglobata</em> (Linnaeus, 1758), <em>Oenopia oncina</em> (Olivier, 1808), <em>Propylea quatuordecimpuctata</em> (Linnaeus, 1758), <em>Psyllobora vigintiduopunctata</em> (Linnaeus, 1758), <em>Scymnus syriacus</em> (Marseul, 1868), <em>Scymnus mongolicus </em>(Weise, 1890).

Changes in numbers of adult Coccinellids on nettles infested with Microlophium evansi (Theo.) and on three experimental bean plots infested with Aphis fabae Scop. are described for the spring and summer of 1952 at Rothamsted. Of the three common species, Adalia bipunctata (L.), Coccinella septempunctata L. and Propylea quatuordecimpunctata (L.), the first was always the most abundant.The overwintered Coccinellids produced two broods: one on nettles in the spring and one on beans in early summer.On bean plots, changes in numbers of the adult insects occurred in three phases: (1) overwintered ladybirds, dispersing from nettles and other places, accumulated on the beans in the early stages of the infestations by Aphis fabae; (2) ladybirds, which had developed from eggs laid by the overwintered insects on nettles, emigrated from nettles and accumulated on the beans when A. fabae populations were at their height; (3) ladybirds, developed from eggs laid on the beans also by the overwintered insects, reached the adult stage when the bean aphid infestations had finished. The rise and fall of the A. fabae populations are discussed.One of the bean plots had always a high population of Coceinellids, which was attributed to its situation between two of the nettle sites. The other two bean plots were remote from nettles and one was sheltered by trees and buildings; their coccinellid populations were much lower.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.

The World Health Organization's (WHO's) 2001 International Classification of Functioning Disability and Health (ICF) has as one of its central tenets the full inclusion of persons with disabilities in society. It acknowledges the need for medical and rehabilitation intervention in its biopscychosocial framework. However, the WHO realizes that society must do its part to facilitate this full participation and empowerment. Persons with complex communication needs (PWCCN) often need augmentative and alternative communication (AAC) in order to express themselves. However, in order to access and successfully use AAC, PWCCN need access to the necessary AAC devices and services, as well as a willing society to interact with them as full contributing members of society. The factors outside of a person's specific physical and/or cognitive functional limitations are addressed in the ICF via the Personal and Environmental Factors. Personal Factors include the individual's personality traits, lifestyle, experiences, social/educational/professional background, race, gender, and age. Environmental Factors include community support systems, social service agencies, governments, social networks, and those persons that interact with the PWCCN. This article addresses the sociopolitical influences on PWCCN and their functioning from a human rights perspective. The necessary introspective role of speech-language pathologists in this process is explored.
