M. Steidle * Institute of Zoology/Animal Ecology 220c, Hohenheim University, Garbenstr. 30, Stuttgart 70599, Germany; steffi[email protected] (S.N.); [email protected] (M.P.) * Correspondence: [email protected]; Tel.: +49-711-23667 Academic Editors: Christos Athanassiou, Nickolas Kavallieratos, Vincenzo Palmeri and Orlando Campolo Received: 28 June 2016; Accepted: 27 July 2016; Published: 1 August 2016 Abstract: Legal requirements and consumer demands for residue-free products pose a big challenge for pest control in grain stores. One possible alternative to chemical insecticides is biological pest control with the pteromalid wasp Lariophagus distinguendus against the weevils Sitophilus granarius, S. oryzae (Coleoptera: Dryophtoridae), and many other storage pest beetles. The use of this wasp as a biocontrol agent was already suggested in 1919 by Prof. Dr. Hase [1]. Despite many studies on host-finding and behavioral biology, the applied aspect was neglected until 1994. Nowadays the wasps are commercially available and can now even be reared on-site, facilitating their use tremendously. This review highlights the milestones in L. distinguendus research, gives insights in current studies, and ventures a glimpse into the future. Keywords: biological pest control; Pteromalidae; Lariophagus distinguendus; Sitophilus sp.; Stegobium paniceum; stored product protection 1. Introduction Stored grain is threatened by a vast number of storage pests, mostly insects [2]. Nowadays integrated pest management strategies (IPM) have superseded the excessive application of chemical insecticides used against storage pests in the past. -

Further Studies of Olfaction in Lariophagus Distinguendus Först
FURTHER STUDIES OF OLFACTION IN LARIOPHAGUS DISTINGUENDUS FÖRST. (HYM., PTEROMALIDAE) by AHMED H. KASCHEF (Entomology Department, Faculty of Science, Ain Shams University, Cairo (Abbassieh) ) (With 4 Figures) (Rec. 8-111-1963) INTRODUCTION HASE (1924) pointed out that the Chalcid parasite Lariophagus disting- uendus F6rst. seems to thrive better in cultures of the bread beetle Stego- bium paniceun2 L. than in cultures of the wheat weevil Calandra granaria L. A detailed account of the behaviour of L. d.istinguendus F6rst. was given by the author (1959) and it has been shown that the female of this parasite finds its host mainly by the sense of smell which resides entirely in the antennae. More recently, KASCHEF (1959 & ig6i ) showed that L. disting- uendus could be reared from two new hosts, Rhizopertha dominica Fab. and Gibbiuni psylloides Czemp. It seemed, therefore, worthwhile to investi- gate the oviposition responses of this parasite to the odour of the following five hosts: Calandra granaria L., C. oryzae L., Stegobium pauiceuvr2 L., Rhizopertha dominica Fab. and Gibbium psylloides Czemp. MATERIAL AND METHODS All the experiments were carried out in a dark room with a light inten- sity of i5 lux, and having an average temperature of 23° C. and relative humidity of 45%. The insects to be tested were taken from the feeding jars immediately before the experiment. The duration of each test was usually one hour after which the insect was replaced in its original culture. The apparatus used (Fig. i ) is in form of a wooden chamber 22 X 7 X 4.5 cm. The base is relatively thick and has seven holes each of 2.5 cm. -

Analisi Di Alcune Invasioni Sostenute Da Ptinidae E Latridiidae in Abitazioni Italiane (Coleoptera)
Quaderni del Museo Civico di Storia Naturale di Ferrara - Vol. 6 - 2018 - pp. 83-86 ISSN 2283-6918 Analisi di alcune invasioni sostenute da Ptinidae e Latridiidae in abitazioni italiane (Coleoptera) MORENO DUttO già Collaboratore Entomologia Medica ed Urbana, Servizio Igiene e Sanità Pubblica, Dipartimento di Prevenzione ASL CN1, Cuneo E-mail: [email protected] Riassunto Nel presente contributo sono segnalate alcune invasioni di ambienti abitativi sostenute da Ptinidae e Latridiidae (Coleoptera) i quali annoverano specie non tipicamente infestanti e, generalmente, poco comuni nei contesti urbani. Nei casi analizzati le invasioni di due specie di Ptinidae – Gibbium psylloides (Czempinski, 1778) (3 casi), Niptus hololeucus (Faldermann, 1835) (1 caso) – e una di Latridiidae – Cartodere constricta (Gyllenhal, 1827) (3 casi) – hanno coinvolto abitazioni con caratteristiche strutturali/costruttive peculiari, idonee a formare e conservare microhabitat con condizioni microclimatiche differenti dai restanti ambienti e dall’ambiente esterno. Sono state interessate dalle invasioni abitazioni storiche di centri urbani (Piemonte, Lazio) (5 casi) aventi in comune, la maggiorparte (4 casi), recenti interventi di ristrutturazione, e in due casi abitazioni di montagna (Piemonte-Valle d’Aosta). In alcuni casi si può ipotizzare che tali invasioni siano da relazionare con l’attività di “disturbo” dei microhabitat di sviluppo indotta dagli interventi edilizi che hanno favorito il passaggio degli insetti negli ambienti attigui abitati e con condizioni ambientali/microclimatiche non propriamente tipiche per il loro sviluppo. In tutti i casi le invasioni si sono risolte nell’arco di 6 mesi, attraverso il controllo dell’umidità relativa ambientale che è stata mantenuta o riportata a valori normali per le unità abitative (55-60%), mentre in due casi i ripetuti ed intensi interventi di disinfestazione si sono rivelati completamente inefficaci. -

Children Hospitalized for Myiasis in a Reference Center in Uruguay
Boletín Médico del Hospital Infantil de México RESEARCH ARTICLE Children hospitalized for myiasis in a reference center in Uruguay Martín Notejane1,2*, Cristina Zabala1,2, Lucía Ibarra2, Leticia Sosa2, and Gustavo Giachetto1,2 1Clínicas Pediátricas, Facultad de Medicina, Universidad de la República; 2Hospital Pediátrico, Centro Hospitalario Pereira Rossell. Montevideo, Uruguay Abstract Background: Myiasis is an emerging disease caused by tissue invasion of dipteran larvae. In Uruguay, Cochliomyia homini- vorax and Dermatobia hominis are the most frequent species. This study aimed to describe the epidemiological and clinical characteristics and the follow-up of children < 15 years hospitalized for myiasis in a reference center in Uruguay between 2010 and 2019. Methods: We conducted a descriptive and retrospective study by reviewing medical records. We analyzed the following variables: age, sex, comorbidities, origin, the month at admission, clinical manifestations, other parasitoses, treatments, complications, and larva species identified. Results: We found 63 hospitalized children: median age of 7 years (1 month–14 years), 68% of females. We detected risk comorbidities for myiasis (33%), of which chronic malnutrition was the most frequent (n = 6); 84% were from the south of the country; 76% were hospitalized during the summer. Superficial and multiple cutaneous involvements were found in 86%: of the scalp 50, furunculoid type 51, secondary to C. hominivorax 98.4%, and to D. hominis in 1.6%. As treatments, larval extraction was detected in all of them, surgical in 22%. Asphyctic products for parasites were applied in 94%, ether in 49. Antimicrobials were prescribed in 95%; cephradine and ivermectin were the most frequent. About 51% presented infectious complications: impetigo was found in 29, cellulitis in 2, and abscess in 1.
