Tick Infestation, Distribution, Identification, And Risk Factors On Large Ruminants In Southern Regions Of Pakistan, Muhammad Jamil, Muhammad Imran, Mukhtar Ahmad, Fawad Ahmad, Mubarik Ali, Abdul Basit, Atta Ur Rehman, Gul Muhammad, Norina Jabeen

Journal of Bioresource Management

The livestock sector plays fundamental role in Pakistan's economy, and a variety of ruminants (cattle and buffaloes) are raised to meet the rising demand for milk, meat, and hide goods. Ticks are the most common vectors for the transmission of tick-borne disease and several pathogens to animals and people. Ticks are widespread in Pakistan due to the country's favorable subtropical climate, and they parasitize large and small ruminants, causing infestation and mortality, as well as economic losses to herdsmen. Therefore, the study aimed to investigate the tick’s epidemiology in large animals in the selected Southern regions of Pakistan, during the …

Journal of Bioresource Management

Animal production is highly affected due to ticks and diseases caused by ticks. Tick control is critical for the economic well-being of the animal industry. This study focused on anti-tick properties of the Neem, Azadirachta indica extracts against Rhipicephalus sanguineus in vitro conditions. R. sanguineus exhibited a high (P < 0.05) dose revolting reaction to A. indica. There were no significant differences in reaction magnanimity between both sexes. The essence also prominently (p < 0.05) retarded the shedding of 60 % of R. sanguineus engorged nymphs. It resulted in that mortality percentage increasing with an increase in the dose of A. indica. At 20 % of A. indica, 87.76 % of tick …

Taxonomic Placement And Nomenclatural Revisions For Five Species Of Neotropical Buprestidae (Coleoptera), Norman E. Woodley

Insecta Mundi

Autarcontes lopezi Fisher, 1925 (Coleoptera: Buprestidae), is transferred to the genus Agrilus Curtis, 1825 (new combination). Colobogaster bella Kirsch, 1873, is transferred to the genus Chrysobothris Eschscholtz, 1829 (new combination). Ectinogonia isamarae Moore, 1994, is resurrected as the valid name for the species previously called E. obscuripennis Cobos, 1954, as the latter is unavailable as infrasubspecific. Conognatha jakobsoni Obenberger, 1928, is resurrected over C. germaini Théry in Hoscheck, 1934, as the for­mer name has priority. Callimicra lucida Waterhouse, 1889, is resurrected as the valid name over C. hoscheki Obenberger, 1922, which has been used due to …

Nesting Behavior Of The Spider Wasp Calopompilus Pyrrhomelas (Walker) (Hymenoptera: Pompilidae), Frank E. Kurczewski, Marshal Hedin, Rick C. West

Insecta Mundi

The nesting behavior of the spider wasp Calopompilus pyrrhomelas (Hymenoptera: Pompilidae: Pepsini) is described for the first time based on independent observations and photographic series from Oak­land, Alameda County, CA; Denio, Humboldt County, NV; and Tamalpais-Homestead Valley, Marin County, CA, respectively. The three wasps captured, immobilized, and provisioned the spider’s own burrows with Cal­isoga longitarsis (Simon) (Nemesiidae) and Antrodiaetus montanus (Chamberlin and Ivie) (Antrodiaetidae).

The genus Calopompilus Ashmead is one of the “most primitive” genera in the family Pompilidae as evidenced by its broad hind wings and anal lobe, lack of specialization in wing venation, stout “scolioid” body structure, and …

The Effects Of Prescribed Fire On Ant Community Composition In A Temperate Deciduous Forest, Emma Jones

2023 Midwest Ecology & Evolution Conference

Prescribed fire is a tool commonly used in land management to decrease wildfire frequency and promote plant diversity. However, the effects of prescribed fire on invertebrate communities, especially those within temperate deciduous forest, are poorly understood. We measured the response of epigeic ant communities in mixed mesophytic forest in Berea, Kentucky following prescribed burning. We used pitfall traps to repeatedly sample epigeic ants in replicate burned and unburned plots for up to 21 months postburn following two separate (2021 and 2022) prescribed fires. Ant species richness was similar between treatments (burn vs. control) and by burn year. Ant community composition …

Evolution Of A Genus Of Gall Wasp Kleptoparasites, Guerin E. Brown

2023 Midwest Ecology & Evolution Conference

Kleptoparasites do not directly parasitize their hosts but instead steal food and resources, reducing host fitness. Like direct parasites, kleptoparasites can be highly dependent on their hosts such that their evolutionary histories may be linked. Here, we study the evolution of a kleptoparasitic wasp genus, Synergus (Hymenoptera: Cynipidae: Synergini), in relation to their hosts, oak gall wasps (Hymenoptera: Cynipidae: Cynipini). Ovipositing oak gall wasps induce the formation of galls on oaks (Fagaceae) that provide food and shelter to one or more developing gall wasps. Galls induced by different gall wasp species are diverse in size, shape, color, and location …

Environmental Factors Shaping A Sawfly-Associated Community Of Parasitoids, Carson Kephart, Robin K. Bagely

2023 Midwest Ecology & Evolution Conference

A major goal of evolutionary biology is to understand the mechanisms that shape biodiversity, especially amongst highly speciose lineages such as parasitic wasps. However, most of these lineages are poorly described, with very little available natural history information. This lack of information limits our ability to uncover the environmental factors that contribute to their patterns of divergence, distribution, and abundance. To that end, here we take advantage of a community of hymenopteran parasites that has an unusually large amount of available information since they attack an economically important pine sawfly species, Neodiprion lecontei. We build upon a set of …

Efficacy Of Biocontrol Against Chrysomelid Pests In Lab Vs Field Studies: Potential Biases Of Setting And Phylogenetic Subgroups, Blake Hudson

2023 Midwest Ecology & Evolution Conference

The beetle family Chrysomelidae is a speciose group of voracious herbivores with a wide number of ecological implications. While some Chrysomelid species have been introduced or augmented as biological control agents of invasive plants, many other species have found success as economically important pests of field crops and stored grains, leading to severe yield losses in cucurbits, legumes, and other systems. Controlling such pests, especially in the field, is particularly difficult due to the timing of their complex life cycles, the fossorial nature of many species’ larvae, and ability to produce multiple generations in a single growing season. This study …

Myzus Fataunae Shinji (Hemiptera: Aphididae), Pilea Aphid, New To North America, Susan E. Halbert, Jade S. Allen, Matthew R. Moore, Katherine E.O. Fairbanks, Masakazu Sano, Gary L. Miller

Insecta Mundi

Minute aphids belonging to the species Myzus fataunae Shinji (Hemiptera: Aphididae) were found at a nursery in Seminole County, Florida. Morphological and molecular data support this determination. The Florida population only colonized species of Pilea Lindl. in our host range experiments. It did not colonize Fatoua villosa. Nakai. Likewise, it did not colonize tested common Florida species of Urticaceae other than Pilea spp. Myzus fataunae is adventive, and it appears to be established in the United States.
