Get PDFWith an acetic acid trap, ten new Diptera species for the fauna of Albania were caught in the Valbona Valley National Park
HEYNEA TRIJUGA: POTENTIAL INSECTICIDAL & GROWTH AND DEVELOPMENT ACTIVITY AGAINST SPILARCTIA OBLIQUA (LEPIDOPTERA: ARCTIIDAE)
Get PDFPlants are recognized as an important natural source of pesticides. They have a diverse range of chemicals to protect themselves against various pests/diseases. Extracts of the fruit pericarp of Heynea trijuga were evaluated for pesticidal and insect growth regulator (IGR) activity against Spilarctia obliqua under laboratory conditions. For three generations castor leaves treated with hexane and acetone extracts of Heynea trijuga (1-10%) were fed to 3rd instar larvae for five days and then untreated fresh leaves were given till pupation. An adverse morphogenic effect on various biological parameters (larval duration, pupal duration, adult emergence and fecundity) was observed in treated insects. The growth and development of insects were significantly affected in a dose-dependent manner. Larval duration, larval mortality, prepupal mortality, postpupal mortality and pupal duration increased with increase in concentration while, larval weight, adult emergence, fecundity and egg fertility decreased with increase in concentrations of extracts. The acetone extract showed better growth regulating activity than the hexane extract. The bioactive substances in H. trijuga extracts could be responsible for behavioral effects and post-ingestive toxicity and have good potential to be developed as insecticide/growth regulators
THE FIG BARK BEETLE HYPOBORUS FICUS ERICHSON, 1836 (COLEOPTERA: CURCULIONIDAE: SCOLYTINAE) IN SERBIA: FIRST RECORDS FOR MORE THAN A CENTURY
Get PDFThe fig bark beetle (Hypoborus ficus Erichson, 1836) was recorded under the bark and in the wood of frost-damaged top branches of fig (Ficus carica L.) in two locations in Vrčin, in the vicinity of Belgrade, as well as in the "Jevremovac" Botanical Garden in Belgrade. Numerous specimens were found, and a total of 39 adults, as well as several larvae and pupae, were collected. The findings presented here are new data on the presence of the mentioned species of bark beetle on the territory of Serbia (the first precise data), after more than a century. This is another Mediterranean species that has been confirmed to have established populations in Serbia
NEW RECORDS OF THE BAT HAWKMOTH, HYLES VESPERTILIO (ESPER, 1780) (LEPIDOPTERA: SPHINGIDAE) IN CROATIA, BOSNIA AND HERZEGOVINA AND SERBIA
Get PDFNew 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 20th 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
ANNOTATED CHECKLIST OF THE SEED BEETLES (COLEOPTERA: CHRYSOMELIDAE: BRUCHINAE) OF TURKEY
Get PDFThe Bruchinae (Coleoptera: Chrysomelidae) fauna of Turkey is reviewed and an annotated checklist is presented, along with the taxa distribution by the country's provinces. In total, 122 species arranged in 14 genera are listed as the seed beetle fauna of Turkey, which constitutes approximately 25% of the Palaearctic Bruchinae fauna. Additionally, the questionable or problematic records of 11 species are evaluated separately
NEW RECORDS FOR THE FAUNA AND ZOOGEOGRAPHY OF CUCKOO WASPS (HYMENOPTERA: CHRYSIDIDAE) IN THE LOWER VOLGA REGION
Get PDFThe 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
CONTRIBUTION TO THE KNOWLEDGE OF APHROPHORID SPITTLEBUGS (HEMIPTERA: APHROPHORIDAE) FROM MOROCCO
Get PDFThis paper lists the current fauna of Aphrophoridae family in Morocco. Distribution data of their occurrence in the country are provided. Nine species of aphrophorid spittlebugs found in Morocco are listed, five of them identified and described for the first time in the country and four other species reported in the literature. An identification key of aphrophorid genera and species is given. The Mediterranean spittlebug Philaenus tesselatus Melichar, 1899 (Moroccan specimen) is described and differentiated from the European meadow spittlebug Philaenus spumarius Linnaeus, 1758 (Italian specimen). The newly reported Philaenus sp. specimen found in Morocco is described
FIRST RECORD OF DISEPYRIS KIEFFER (HYMENOPTERA: BETHYLIDAE) FROM IRAN
Get PDFDisepyris 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
FIRST RECORD OF ALIEN BULB-AND-POTATO APHID RHOPALOSIPHONINUS LATYSIPHON (HEMIPTERA: APHIDIDAE) IN SERBIA
Get PDFThe North American aphid Rhopalosiphoninus latysiphon (Davidson, 1912) (Hemiptera: Aphididae) was found in Serbia for the first time. It is a polyphagous species, mainly feeding on roots, bulbs and tubers. This cryptic living species was detected in yellow water traps on fields of the Institute of Field and Vegetable Crops, Novi Sad (Rimski Šančevi) during the monitoring of aphid flight activity in sugar beet. In total, three specimens were trapped in 2019 and 2020. The main morphological and biological characteristics of the species are given in the text
