Abstract: Predatory soil-dwelling mites, Gaeolaelaps aculeifer (Canestrini) and Stratiolaelaps scimitus (Womersley) (Mesostigmata: Laelapidae), are essential biocontrol agents of small soil arthropod pests. To understand the population characteristics of these two predatory mites, we investigated their development, survival, and fecundity under laboratory conditions. We used Tyrophagus putrescentiae (Schrank) as a food source and analyzed the data using the age-stage, two-sex life table. The duration from egg to adult for G. aculeifer was longer than that for S. scimitus, but larval duration was similar Citation: Park, J.; Mostafiz, M.M.; between the two species.

Preliminary Notes on the Use of the Predatory Soil Mite Stratiolaelaps Scimitus (Acari: Laelapidae) As a Biological Control Agent for Acariasis in Lizards Robert W
Preliminary Notes on the Use of the Predatory Soil Mite Stratiolaelaps scimitus (Acari: Laelapidae) as a Biological Control Agent for Acariasis in Lizards Robert W. Mendyk, BS, MA Department of Herpetology, Smithsonian National Zoological Park, 3001 Connecticut Ave. NW, Washington, DC 20008, USA Current address: Department of Herpetology, Jacksonville Zoo and Gardens, 307 Zoo Parkway, Jacksonville, FL 32218, USA ABSTRaCT: While commonly employed by the agricultural and horticultural industries, biological control has rarely been utilized in herpetological husbandry to treat infectious or parasitic diseases. This case study describes the use of the predatory soil mite Stratiolaelaps scimitus to treat parasitic mite infestations in two adult inland bearded dragons (Pogona vitticeps). Stratiolaelaps scimitus applied directly to the existing terrarium substrate appeared to have eliminated all traces of parasitic mite infestation in both lizards within 5 days. These results, although preliminary, highlight the potential utility of predatory mites and other biological control agents in the husbandry and veterinary management of reptiles in captivity. KEY WORDS: Acariasis, biological control, Hypoaspis miles, lizards, predatory mites, Stratiolaelaps scimitus. INTRODUCTiON CaSE REPORT Hematophagic and lymphophagic mites are common A sexual pair of adult inland bearded dragons (Pogona parasites of reptiles in captivity, where they can spread vitticeps) was acquired by a private keeper in 2007.

Compatibility Conflict: Is the Use of Biological Control Agents with Pesiticides a Viable Management Strategy?
Cloyd _______________________________________________________________________________________ COMPATIBILITY CONFLICT: IS THE USE OF BIOLOGICAL CONTROL AGENTS WITH PESITICIDES A VIABLE MANAGEMENT STRATEGY? Raymond CLOYD Department of Natural Resources and Environmental Sciences 384 National Soybean Research Laboratory 1101 West Peabody Drive Urbana, IL 61801, U.S.A. [email protected] ABSTRACT Biological control or the use of natural enemies is an alternative pest management strategy for dealing with arthropods. However, natural enemies may not always provide adequate con- trol of plant-feeding insects and mites in greenhouses. As a result, research has assessed the concept of using natural enemies in conjunction with pesticides and the potential compatibil- ity when both pest management strategies are implemented together. There are a variety of 546 factors that influence the ability of using natural enemies with pesticides, these include whether the natural enemy is a parasitoid or predator, natural enemy species, life stage sensitivity, rate of application, timing of application, and mode of action of a particular insecticide or miti- cide. Pesticides may impact natural enemies by affecting longevity (survival), host acceptance, sex ratio, reproduction (fecundity), foraging behavior, percent emergence, and development time. In our studies, we have found a number of pesticides to be compatible with the natural enemies of the citrus mealybug, Planococcus citri and fungus gnats, Bradysia spp. For ex- ample, we have demonstrated that foliar and drench applications of the insecticides novaluron and pyriproxyfen, and the fungicides fosetyl-Al and mefenoxam to be compatible with the predatory mite, Stratiolaelaps scimitus. We have also shown that the insecticides azadirachtin and pyriproxyfen are compatible with the citrus mealybug parasitoid, Leptomastix dactylopii. -
New Records of Springtail Fauna (Hexapoda: Collembola: Entomobryomorpha) from Ordu Province in Turkey
Turkish Journal of Zoology Turk J Zool (2017) 41: 24-32 http://journals.tubitak.gov.tr/zoology/ © TÜBİTAK Research Article doi:10.3906/zoo-1509-28 New records of springtail fauna (Hexapoda: Collembola: Entomobryomorpha) from Ordu Province in Turkey 1 2, 3 Muhammet Ali ÖZATA , Hasan SEVGİLİ *, Igor J. KAPRUS 1 Demir Karamancı Anatolian High School, Melikgazi, Kayseri, Turkey 2 Department of Biology, Faculty of Arts and Sciences, Ordu University, Ordu, Turkey 3 State Museum of Natural History, Ukrainian National Academy of Sciences, L’viv, Ukraine Received: 14.09.2015 Accepted/Published Online: 27.04.2016 Final Version: 25.01.2017 Abstract: This study aims to elucidate the Collembola fauna of the province of Ordu, which is situated between the Middle and Eastern Black Sea regions of Turkey. Although a large number of Collembolan specimens had been collected, only Entomobryomorpha species were given emphasis. From 44 different sampled localities of the province of Ordu, we recorded 6 families, 14 genera, and 28 species. Six of these species were previously recorded and 20 of them are new records for Turkey. The results were not surprising, considering that the sampled region had not been studied previously, quite like many habitats in Turkey. With our 20 new records (Entomobryomorpha), the grand total of the springtail fauna of Turkey is increased to 73 species. This represents an increase of almost 40% of the current list of known species. These numbers show us that the diversity of Collembola in Turkey is not thoroughly known and it is clear that numerous species remain undiscovered or undescribed. -

For Controlling the Root-Knot Nematode, Meloidogyne Incognita (Tylenchida: Heteroderidae) Si-Hua Yang1,2, Dan Wang1,2, Chun Chen1, Chun-Ling Xu1 & Hui Xie1*
www.nature.com/scientificreports There are amendments to this paper OPEN Evaluation of Stratiolaelaps scimitus (Acari: Laelapidae) for controlling the root-knot nematode, Meloidogyne incognita (Tylenchida: Heteroderidae) Si-Hua Yang1,2, Dan Wang1,2, Chun Chen1, Chun-Ling Xu1 & Hui Xie1* Root-knot nematodes are one of the most harmful plant-parasitic nematodes (PPNs). In this paper, the predation of Stratiolaelaps scimitus against Meloidogyne incognita was tested in an individual arena, and the control efciency of the mite on the nematode in the water spinach (Ipomoea aquatica) rhizosphere was studied with a pot experiment. The results showed that S. scimitus could develop normally and complete its life cycle by feeding on second-stage juveniles of M. incognita (Mi-J2). The consumption rate of a 24 h starving female mite on Mi-J2 increased with the increase of prey density at 25 °C. Among the starvation treatments, the nematode consumption rate of a female mite starved for 96 h at 25 °C was highest; and among temperature treatments, the maximum consumption rate of a 24 h starving female mite on Mi-J2 was at 28 °C. The number of M. incognita in the spinach rhizosphere could be reduced efectively by releasing S. scimitus into rhizosphere soil, and 400 mites per pot was the optimum releasing density in which the numbers of root knots and egg masses decreased by 50.9% and 62.8%, respectively. Though we have gained a greater understanding of S. scimitus as a predator of M. incognita, the biocontrol of M. incognita using S. scimitus under feld conditions remains unknown and requires further study. -
