AN OVERVIEW ON THE SUBFAMILY CREMASTINAE FÖRSTER, 1869 (HYMENOPTERA: ICHNEUMONIDAE) FROM TURKEY

Saliha Çoruh — 2022-03-07

Fauna of the subfamily Cremastinae Förster, 1869 (Ichneumonidae: Hymenoptera) on the territory of Turkey was investigated. The survey was conducted during the period 1995-2020. A total of 54 species belonging to eight genera have been listed. Among the material collected in the past 25 years, the species Cremastus brevicornis Kolarov & Beyarslan, 1999; C. kasparyani Kolarov Gürbüz & Birol, 2014; C. petiolaris Kolarov & Beyarslan; 1999; C. tristator Aubert, 1970; Nothocremastus beyarslani Kolarov, 1997 and Temelucha turcata Kolarov & Beyarslan, 1999 were listed as endemic to the investigated teritorry. Additionally, a male of Eucreamastus priebei Kolarov, 1999 is recorded for the first time from Turkey. Turkish species of the subfamily Cremastinae have been analyzed according to biogeographical and zoоgeographical features.

LARVICIDAL EFFECT OF SELECTED SALTS AGAINST THE DENGUE VECTOR MOSQUITO AEDES AEGYPTI (DIPTERA: CULICIDAE) IN BANGLADESH

Mohammad Zaglul Haider Iqbal — 2022-03-07

The container breeding mosquito Aedes aegypti (Linnaeus) is the major universal vector of dengue viruses that cause dengue fever (DF), dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Vector control has an important role in reducing human cases of DHF/DSS. The purpose of this work was to evaluate the larvicidal effect of salt solutions against the larvae of Ae. aegypti. Freshly collected larvae were transferred to the laboratory and reared using rainwater as the rearing medium, with yeast granules as larval food. Five salts, AgNO₃, HgCl₂, CdCl₂, CuSO_4,and CuCl₂, were tested to assess the larvicidal effect on both the 1^st and 3^rd instar larvae of Ae. aegypti. Serial concentrations (0, 1, 3, 5, 7 and 10 ppm) of each salt were prepared using distilled water as the solvent. Silver nitrate (AgNO₃) was noted as the most effective larvicide, followed by HgCl₂, CdCl₂, CuSO_4,and CuCl₂. The LC₅₀ values of AgNO₃ against 1^st and 3^rd instar larvae were 0.118 and 1.659 ppm, and the LC₉₀ values were 2 and 3.347 ppm, respectively. The LT₅₀ values of AgNO₃(1 ppm) against 1^st and 3^rd instar larvae were 0.575 and 30.42 h, and the LT₉₀ values were 6.00 and 67.49 h, respectively. All 1^st instar larvae died, failing to pupate in every salt concentration (1-10 ppm) within 7 days. Third instar larvae were also unable to pupate entirely in AgNO₃ and HgCl₂ solutions but a very few (5.00-36.66%) pupations were found at 7 ppm, with higher concentrations of CdCl₂, CuSo₄ and CuCl₂ salts. In addition, CdCl₂, CuSo₄ and CuCl₂ prevented 66.66%, 57.14% and 50% of adult emergences from pupae at 5 ppm concentration, respectively. The order of decrease of toxicity for larval mortality was AgNO₃>HgCl₂>CdCl₂>CuSO₄>CuCl₂, and in preventing pupation and adult emergence it was AgNO₃≥HgCl₂>CdCl₂>CuSO₄>CuCl₂. AgNO₃ was found to have very good potential in the killing of Aedes aegypti larvae, prevention of pupae formation and adult emergence. Therefore, the results obtained could be considered a contribution to the search for eco-friendly larvicides of natural origin. Further studies are needed to understand the residual aquatic toxicity of this salt in the field.

FIRST RECORD OF DISEPYRIS KIEFFER (HYMENOPTERA: BETHYLIDAE) FROM IRAN

Nahid Khajeh — 2022-03-17

Disepyris Kieffer, a small genus of Bethylidae (Hymenoptera), is recorded for the first time from Iran, represented by D. niveus Lim & Azevedo. Members of this genus can be easily recognized by the protarsi of females with delicate long spines and forewing with short 2r-rs&Rs vein. The diagnostic characters of species are briefly presented according to the newly collected specimens with reference to the respective illustrations.

THE FIRST RECORD OF THE WEB-SPINNING SAWFLY CAENOLYDA RETICULATA (LINNAEUS, 1758) (HYMENOPTERA: SYMPHYTA: PAMPHILIIDAE) FROM THE BALKANS

Mihailo D. Vujić — 2022-03-23

During project field activities conducted in May 2021 in the territory of the Landscape of Outstanding Features “Dolina Pčinje” at the locality Vogance, one dead and trampled specimen of the web-spinning sawfly Caenolyda reticulata (Linnaeus, 1758) was found. The new finding is the first report of the species from Serbia, as well as from the Balkans, and significantly expands its known distribution into southeast Europe. The host plants of this species are pines (Pinus spp.), of which black pine (Pinus nigra subsp. nigra) occurs in the Pčinja River valley.

NEW RECORDS OF THE BAT HAWKMOTH, HYLES VESPERTILIO (ESPER, 1780) (LEPIDOPTERA: SPHINGIDAE) IN CROATIA, BOSNIA AND HERZEGOVINA AND SERBIA

Toni Koren — 2022-03-28

New records of Hyles vespertilio (Esper, 1780) are reported from Croatia, Bosnia and Herzegovina and Serbia. In Croatia, a single specimen was recorded on Mt. Biokovo, within the Biokovo Nature Park, southern Croatia. This is the first record in the country in 44 years. In Bosnia and Herzegovina, the species was recorded at 11 localities within or in the near surroundings of the Blidinje Nature Park. This species is new to the fauna of Bosnia and Herzegovina and is the 20^th Sphingidae species recorded in the country. In Serbia, the species was recorded in Krajinoviće, Mt. Giljeva. This is the third known record and the first observation for this country in 32 years. The preferred host plant, Epilobium dodonaei, is present at all the studied localities in Croatia and Bosnia and Herzegovina, but the caterpillars were not surveyed during this work. These findings could be treated as resident populations of the bat hawkmoth, since the species is considered nonmigratory, and the host plant is present in the study areas.

NEW RECORDS FOR THE FAUNA AND ZOOGEOGRAPHY OF CUCKOO WASPS (HYMENOPTERA: CHRYSIDIDAE) IN THE LOWER VOLGA REGION

Alexey N. Volodchenko — 2022-04-25

The fauna and zoogeography of chrysidids in the steppe and forest biocenoses of the Lower Volga region in the Saratov region were studied, which include 92 species and 2 subspecies from 17 genera: Cleptes – 2 species; Colpopyga – 1; Elampus – 8; Haba – 1; Hedychridium – 6; Hedychrum – 5; Holopyga – 11; Omalus – 2; Philoctetes – 3; Pseudomalus – 5; Chrysidea – 1; Chrysis – 41; Chrysura – 3; Spinolia – 1; Stilbum – 2; Trichrysis – 1 and Parnopes – 1, among which 69 species are presented for the Saratov region for the first time. Two species, Chrysis corusca Valkeila, 1971 and Chrysis vanlithi Linsenmaier, 1959, and one subspecies Chrysis frivaldszkyi sparsepunctata du Buysson, 1895, are new records for the Russian fauna. The obtained data broaden the understanding of the fauna and diversity of Chrysididae in the Saratov region and the Lower Volga region and supplement the fauna list of the Chrysididae of Russian fauna.
