The Argentine ant, Linepithema humile (Mayr), is an insect native to South America, but an invasive species in many parts of the world. It is globally distributed. Linepithema humile is considered a pest species, primarily due to its feeding habits of tending and protecting honeydew producing insects, such as scale insects, which are often damaging to crops and ornamental plants. This aggressive, populous ant species also has a negative effect on native ant species. Linepithema humile colonies have multiple queens, allowing colonies to grow and spread rapidly. Under certain conditions, the argentine ant may also become a household pest if it finds a way into homes. Linepithema humile has been designated as a tramp ant species, meaning that it has an incredible ability to spread and establish in new areas and is difficult to control. Linepithema humile, like other tramp species, can establish in new locations quickly due to the multi-queen nature of the colonies, their abitlity to forage and find resources, and the extensive network of interrelated colonies they are able to form. This document provides an in-depth synopsis of the insect's life history, biology, and management.

First Time

A invasive rugose spiraling whitefly (RSW) <em>Aleurodicus rugioperculatus</em> Martin (Hemiptera: Aleyrodidae) was found infesting coconut, banana, custard apple and several ornamental plants in Tamil Nadu, Andhra Pradesh and Kerala for the first time in India. The identity of the pest species was determined through morphological and molecular tools. Furthermore cytochrome c oxidase-I gene (658 bp) of RSW was sequenced (GenBank accession number KY209909) which would serve as an ideal molecular diagnostic marker for its identification irrespective of its phenotypic plasticity. During the survey, several natural enemies were recorded and maximum parasitism was recorded by <em>Encarsia guadeloupae</em> Viggiani (Hymenoptera: Aphelinidae) and its COI gene was sequenced and deposited as <em>Encarsia</em> sp. (GenBank accession number KY223606). Per cent parasitism ranged from 20.0 to 60.0 % in different collection locations, highest parasitism being recorded in Kerala as compared to other states. The predators recorded were <em>Mallada</em> sp., few coccinellids and predatory mites. This communication is the first report of the rugose spiraling whitefly, its host plant range and associated natural enemies in India.

The City

New geolocated records of the invasive ant Linepithema humile (Mayr, 1868) are added to the previous references for the city of Madrid and its surroundings, and the possible causes of the occurrence and permanence of this species in urban areas are discussed. The data collection corresponds to a series of samplings carried out for the last three years in green areas of the city, bibliographic searches, citizen science platforms and personal communications. To date, eleven locations in the urban area of Madrid and four points outside the city have been registered. The city of Madrid is undergoing a colonisation by the Argentine ant, although it is not widespread yet, since observations over time and space are isolated and apparently unrelated. However, this species has a great capacity to disperse and establish new colonies, mainly human-mediated through the transport of goods, plants, gardening tools, etc. Considering the numerous colonizable urban green areas in the city that can provide the necessary conditions for its expansion, the Argentine ant should not be underestimated, and immediate action is strongly recommended.

A preliminary list of non-indigenous scale insect species on ornamental plants in Bulgaria and China is presented. The sampling was done between April and November, 2009, in the framework of the project “Invasive scale insects on ornamental plants in Bulgaria and China”. The insects were collected in nurseries, parks, gardens, botanical collections and greenhouses. Representatives from four families have been identified in Bulgaria, the most numerous of which are the Diaspididae (eight species), Coccidae (four species), Pseudococcidae (two species) and Margarodidae (one species). Three species of non-indigenous scale insects associated with ornamental plants were collected in China, all belonging to the family Pseudococcidae. A list of alien scale insect species on ornamental plants is given, including the sampling sites, host plants on which they were found, origin and first report in both countries.

Background: Malnutrition is defined as deficiency and or imbalance of nutrients and energy and may produce a negative effect on the growth, maintenance, and specific functions of the body. This study purposed to determine the nutritional situation, to define the presence of malnutrition, to detect the deficiencies of micronutrients of the children admitted to a pediatric tertiary hospital. Methods: A retrospective, cross‑sectional, single unit-based study in pediatric patients admitted to the pediatric wards for differential diagnosis or treatment was conducted between November 2017 and December 2019. The anthropometric measurements were figured out on hospital admission of all pediatric patients. The pediatric patients diagnosed with malnutrition were assessed to detect their nutritional status/feeding habits and to identify any associated factors. Results: A total of 1206 children were hospitalized with an acute illness diagnosis and/or treatment during the study period. One hundred fifteen patients were noted to have malnutrition; acute malnutrition (wasting) (weight for height z-score < - 2 SDS) (n=51/115, 44.3%) and chronic malnutrition (stunted) (height-for-age < −2 SDS) was detected in 64/115 (55.7%) patients; the prevalence of wasting, and stunting was 4.2% and 5.3%, respectively. Conclusions: Our study suggests that it should be performed an assessment of nutritional status/ history and anthropometric measurements every admission to the hospital in order to provide healthy growth development in childhood, particularly under 2 of age and interventions should be strengthened for general child health.
