Leptoglossus occidentalis Heidemann 1910 is known as the western conifer seed bug and is an impor- tant pest species in North America feeding on seeds of conifers. The overwintering adults enter households and factories and cause nuisance to people. This pest species has been introduced in Europe through trans- portation and spread rapidly over the continent after its first appearance in northern Italy in 1999. In Turkey it has been found in Edirne and Kırklareli (Lüleburgaz) in Turkish Thrace in October 2009 and in Novomber 2010, respectively, representing the first record of this alien Nearctic genus and species in the country. This study reports identification characters of the species, its host plants, details about its biology and a map of its most recent distribution throughout Europe. Key words: Leptoglossus occidentalis, Coreidae, distribution, invasion, first record, Turkey.

  • Nuisance Home Invader Pests
    NUISANCE HOME INVADER PESTS Ann Hazelrigg, Ph.D. and Gabriella Maia, M.S. - UVM Plant Diagnostic Clinic February 2018 Every winter and spring we receive many calls, emails and samples in the Plant Diagnostic Clinic regarding insects that have invaded homes. There are typically four different insect home invaders we see in Vermont and none of them breed in the house or cause any damage to humans, pets, food items or structures. These nuisance pests commonly invade warm homes in the late fall looking for a protected place to overwinter and hibernate. WESTERN CONIFER SEED BUG (Leptoglossus occidentalis) BugGuide.Net https://bugguide.net/user/view/28 Tony DiTerlizzi http://www.diterlizzi.com/ The largest of the four pests is the western conifer seed bug (WCSB). This insect feeds primarily on the seeds and developing cones of several species of conifers and their respective hybrids. These true bugs in the order Hemiptera have been expanding their range eastward and it currently extends across the northern US into Canada. Adults are about 3/4 inch long, brownish in color with alternating light and dark bands running along the outer wing edges on the sides of their abdomen. The lower hind leg is widened on each side of the leg and looks like a tiny leaf has been attached. The insects move slowly but can fly and often make buzzing sounds when airborne. WCSB will give off a pungent odor if you handle them. With cold weather, adult western conifer seed bugs search for protected sites to overwinter and therefore become annoyances in and around houses.

  • Western Conifer Seed Bug an Unwanted House Guest
    Western Conifer Seed Bug: An Unwanted House Guest The Western conifer seed bug (Leptoglossus occidentalis Heidemann) has become a nuisance pest to some New York residents. The bug has the habit of entering buildings at the onset of cold weather in the late summer or early fall as it seeks a protected site to spend the winter. These bugs do not bite or sting, nor do they cause damage to the home. They will, however, give off a pungent odor if you handle them, which is part of the insect's defensive strategy. They also may make a buzzing sound when flying. Description: The western conifer seed bug belongs to the family Coreidae, commonly called leaf-footed bugs, and like many members of this family, it has a flattened, leaf- like expansion on the hind legs. The adult is about 3/4 inch (16-20 mm) in length and is dull brownish. There is a faint white zigzag stripe across the midpoint of its upper surface. When the insect takes flight, it lifts the wings to reveal bright yellowish orange areas on its back. These bugs use piercing-sucking mouthparts to pierce the scales of conifer seeds and suck out the seed pulp. The list of host plants includes white pine, red pine, Scotch pine, Austrian pine, mugo pine, white spruce, Douglas fir and hemlock. Often these trees are planted or are growing near homes, and if that is the case, the bugs may seek the Fig. 1. An adult western conifer seed bug.

Car- retera México-Texcoco km 36.5, Montecillo, Texcoco, Estado de México, C.P. 56230 Abstract The metathoracic scent gland of 25-day-old adults of both sexes of the leaf-footed bug, Leptoglossus zonatus (Dallas) (Heteroptera: Coreidae), are described based on optical microscopy analysis. No sexual dimorphism was observed in the glandular composition of this species. The gland is located in the anteroventral corner of the metathoracic pleura between the middle and posterior coxal pits. The opening to the outside of the gland is very wide and permanently open as it lacks a protective membrane. In the internal part, there is a pair of metathoracic glands that consist of piles of intertwined and occasionally bifurcated cellular tubes or columns. These glands discharge their pheromonal contents into the reservoir through a narrow cuticular tube. The reservoir connects with the vestibule via two opposite and assembled cuticular folds that can separate muscularly in order to allow the flow of liquid away from the insect. The external part consists of an ostiole from which the pheromone is emitted.

Salih PARLAK Bursa Technical University, Faculty of Forestry, Bursa, TURKEY [email protected] Received Date: 14.02.2017 Accepted Date: 09.06.2017 Abstract Aim of study: Leptoglossus occidentalis which is first identified by Heidemann at North America in 1910 spread quickly after WW II. Although it was first seen in 1999 in Europe has swept the continent in 10 years. First damage observation in Turkey reported in Kozak Basin of Bergama on cones of stone pine trees which has valuable edible seeds. The seed yield loss started in 2005 and reached to a peak in 2009. In addition to high early age conelet loss, rate of emptiness of cones has sometimes reached to 90 %. The bug causes decrement in seed formation and seed germination ability significantly by causing early stage conelet loss and destroying endosperm parts of mature cones. In respect of forestry activities decrement of seed resources caused due to bug damage will have negative impact on natural regeneration activities in Turkey and probably will end in failure. In this study, it was aimed to determine the severity of damage caused by the collecting of cone samples from the stone pine forests in our country. Area of study: Without making any discrimination either planted or natural or any altitude or any aspect, stone pine cones have been collected from 42 localities which are distributed all around Turkey.

Milichiella lacteipennis fue atraída solamente a chinches de Coreidae y Pentatomidae, y en general más fuertemente hacia las hembras que a los machos. Cuando eran atraídas, el tiempo de la llegada del primer milichiido a los chinches aplastados tuvo un rango entre 2 a 34 segundos dependiendo del sexo y de la especie de chinche. Solo las hembras adultas de M. lacteipennis fueron atraídas a los chinches. Palabras clave: experimento de atracción, Milichiella, Coreidae, Pentatomidae, Reduviidae, Rhyparochro- midae. SUMMARY Ten species in four hemipteran families: Coreidae, Pentatomidae, Reduviidae, and Rhyparochromidae were crushed by hand to test their attraction towards Milichiella lacteipennis Loew (Diptera: Milichiidae). Milichiella lacteipennis was attracted only to bugs of the families Coreidae and Pentatomidae, and was generally more strongly attracted to females than males. When attracted, the time of arrival of the first milichiid fly to the crushed bugs ranged from 2 to 34 seconds depending on the species and sex of the bug tested.

  • Diversity and Abundance of Insect Herbivores Foraging on Seedlings in a Rainforest in Guyana
    R Ecological Entomology (1999) 24, 245±259 Diversity and abundance of insect herbivores foraging on seedlings in a rainforest in Guyana YVES BASSET CABI Bioscience: Environment, Ascot, U.K. Abstract. 1. Free-living insect herbivores foraging on 10 000 tagged seedlings representing ®ve species of common rainforest trees were surveyed monthly for more than 1 year in an unlogged forest plot of 1 km2 in Guyana. 2. Overall, 9056 insect specimens were collected. Most were sap-sucking insects, which represented at least 244 species belonging to 25 families. Leaf-chewing insects included at least 101 species belonging to 16 families. Herbivore densities were among the lowest densities reported in tropical rainforests to date: 2.4 individuals per square metre of foliage. 3. Insect host speci®city was assessed by calculating Lloyd's index of patchiness from distributional records and considering feeding records in captivity and in situ. Generalists represented 84 and 78% of sap-sucking species and individuals, and 75 and 42% of leaf-chewing species and individuals. In particular, several species of polyphagous xylem-feeding Cicadellinae were strikingly abundant on all hosts. 4. The high incidence of generalist insects suggests that the Janzen±Connell model, explaining rates of attack on seedlings as a density-dependent process resulting from contagion of specialist insects from parent trees, is unlikely to be valid in this study system. 5. Given the rarity of ¯ushing events for the seedlings during the study period, the low insect densities, and the high proportion of generalists, the data also suggest that seedlings may represent a poor resource for free-living insect herbivores in rainforests.

  • Insect Classification Standards 2020
    RECOMMENDED INSECT CLASSIFICATION FOR UGA ENTOMOLOGY CLASSES (2020) In an effort to standardize the hexapod classification systems being taught to our students by our faculty in multiple courses across three UGA campuses, I recommend that the Entomology Department adopts the basic system presented in the following textbook: Triplehorn, C.A. and N.F. Johnson. 2005. Borror and DeLong’s Introduction to the Study of Insects. 7th ed. Thomson Brooks/Cole, Belmont CA, 864 pp. This book was chosen for a variety of reasons. It is widely used in the U.S. as the textbook for Insect Taxonomy classes, including our class at UGA. It focuses on North American taxa. The authors were cautious, presenting changes only after they have been widely accepted by the taxonomic community. Below is an annotated summary of the T&J (2005) classification. Some of the more familiar taxa above the ordinal level are given in caps. Some of the more important and familiar suborders and families are indented and listed beneath each order. Note that this is neither an exhaustive nor representative list of suborders and families. It was provided simply to clarify which taxa are impacted by some of more important classification changes. Please consult T&J (2005) for information about taxa that are not listed below. Unfortunately, T&J (2005) is now badly outdated with respect to some significant classification changes. Therefore, in the classification standard provided below, some well corroborated and broadly accepted updates have been made to their classification scheme. Feel free to contact me if you have any questions about this classification.
