(54) Title: MITICIDAL, INSECTICIDAL AND NEMATOCIDAL COMPOSITIONS CONTAINING PLANTS EXTRACTS FROM BULNESIA SP AND HUMULUS SP 2 (57) Abstract: The present disclosure relates to biopesticide compositions comprising aBulnesia sp. plant extract (e.g., an extract from —- Bulnesia sarmientoi) and a Humulus sp. plant extract (e.g., an extract from Humulus lupulus). In some aspects, the Bulnesia sp. plant 25 extract and the Humulus sp. plant extract act synergistically as miticides. Also provided are methods of manufacture, formulations, and kits comprising the disclosed compositions. The disclosed compositions can be use control, treat, or prevent pest infestations (e.g., by mites, insects, nematodes, etc.) in plants and in animals, including humans, in need thereof. MITICIDAL, INSECTICIDAL AND NEMATOCIDAL COMPOSITIONS CONTAINING PLANTS EXTRACTS FROM BULNESIA SP AND HUMULUS SP BACKGROUND [0001] Mites are among the most diverse and successful of all the invertebrate groups. Many species live as parasites on plants and animals. It is estimated that 48,200 species of mites have been described. Many mites which have been well studied are parasitic on plants and animals. Dust mites feed mostly on dead skin and hair shed from humans. Insects may also be infested by parasitic mites. For example, Varroadestructor, attaches to the body of the honey bee, and Acarapis woodi (family Tarsonemidae) lives in the tracheae of honey bees. [0002] Some of the plant pests include the so-called spider mites (family Tetranychidae), thread-footed mites (family Tarsonemidae), and the gall mites (family Eriophyidae). Among the species that attack animals are members of the sarcoptic mange mites (family Sarcoptidae), which burrow under the skin. Demodex mites (family Demodicidae) are parasites that live in or near the hair follicles of mammals, including humans. [0003] Some species of mites can colonize humans directly, act as vectors for disease transmission, or cause or contribute to allergenic diseases. Mites which colonize human skin are the cause of several types of skin itchy rashes, such as grain itch, grocer's itch, and scabies. [0004] Dust mites cause several forms of allergic diseases, including hay fever, asthma and eczema, and are known to aggravate atopic dermatitis. House dust mites are usually found in warm and humid locations, including beds. It is thought that inhalation of mites during sleep exposes the human body to some antigens that eventually induce hypersensitivity reaction. [0005] Many chemicals which possess insecticidal properties have been found to possess little or no effect in killing mites, whereas other chemicals are toxic to mites in the adult stage but not in the egg stage and hence must be applied at very short intervals in order to control the mites from cycle to cycle. Accordingly, there is a need to provide effective miticide compositions that will control mites from the egg to the adult stage. [0006] Frequent treatment of plants with many chemicals which are effective as miticides results in most instances in serious damage to the plant foliage. Most of the chemicals which have been found effective for the control of mites in plants, shrubs and trees, tend to burn the plant. In many instances substantial injury to the foliage is not tolerable. For example, in the control of mites on ornamental plants, only minor degrees of leaf burn can be tolerated. In other instances, for example in the case of citrus fruits, the injury to the fruit caused by the treating chemical frequently gives rise to a down-grading of the fruit that is scarcely less serious to the fruit grower than the injury caused by the presence of mites on the fruit. [0007] The use of chemicals in miticides is also limited because of their toxicity to humans, pets, farm animals, non-target vertebrate and invertebrate species, and the environment. Thus, there is a need for miticides effective on plants, shrubs and trees with negligible injury to the foliage and fruit, and with no toxicity to humans, pets, farm animals, non-target vertebrate and invertebrate species, and the environment. BRIEF SUMMARY OF THE DISCLOSURE [0008] The present disclosure provides compositions comprising Bulnesia sp. plant extracts and Humulus sp. plant extracts that can be used as biopesticides, for example, against acari (mite, ticks), nematodes, insects, etc. In some aspects, the compositions disclosed herein comprise a Bulnesia sp. extract and a Humulus sp. plant extract, wherein the Bulnesia sp. extract and the Humulus sp. plant extract act synergistically as miticides. [0009] In some aspects, the Bulnesia sp. plant is selected from the group consisting of Bulnesia arborea, Bulnesia bonariensis, Bulnesia carrapo, Bulnesia chilensis, Bulnesia foliosa, Bulnesia loraniensis, Bulnesia macrocarpa, Bulnesia rivas-martinezii, Bulnesia retama, Bulnesia sarmientoi, Bulnesia schickendantzii, and a combination thereof. In some aspects, the Bulnesia sp. plant is Bulnesia sarmientoi. In some aspects, the Humulus sp. plant is selected from the group consisting of Humulus japonicus, Humulus lupulus, Humulus yunnanensis, and a combination thereof. In some aspects, the Humulus sp. plant is Humulus lupulus. [0010] In some aspects, the Humulus sp. plant extract is obtained from Humulus sp. leaves. In some aspects, the Humulus sp. leaves are fresh leaves or dry leaves. In some aspects, the fresh leaves or dry leaves are, e.g., shredded, fragmented, pulverized, or pelletized. [0011] In some aspects, the Humulus sp. plant extract is obtained from Humulus sp. flowers or buds (hop cones) or other plant parts (e.g., roots, stems, bark, etc.). In some aspects, the Humulus sp. plant extract is a supercritical C0 2 extract. In some aspects, the Humulus sp. plant extract is obtained by solvent extraction (e.g., using water, organic solvents, or any combination thereof), soxhlet, ultrasonic extraction, or any other method known in the art. [0012] In some aspects, the Humulus sp. plant extract consists or consists essentially of a blend of hop acids with a high concentration of iso alpha acids. Such blend of hop acids in in some aspects a plant extract that has been enriched in iso alpha acids (e.g., by conversion of alpha acids to iso alpha acids, removal on non-iso alpha acid components, addition of iso alpha acids, or any combination thereof). In some aspects, the concentration of iso alpha acids is at least 75%. In some aspects, the concentration of iso alpha acids is at least 90%. In some aspects, the iso alpha acids are derived from humulone, adhumulone, cohumulone, posthumulone, prehumulone, or any combination thereof. [0013] In some aspects, the Bulnesia sp. plant extract is obtained from Bulnesia sp. wood, root, stems, leaves, and other plant parts. In a specific aspect, the Bulnesia sp. plant extract is obtained from Bulnesia sp. wood. In some aspects, the Bulnesia sp. plant extract is obtained by steam flow extraction. In some aspects, the Bulnesia sp. plant extract is obtained by solvent extraction (e.g., using water, organic solvents, or any combination thereof), soxhlet, ultrasonic extraction, or any other method known in the art. In some aspects, the Bulnesia sp. plant extract is an essential oil. [0014] In some aspects, the Bulnesia sp. plant extract comprises guaiol, bulnesol, hanamyol, or any combination thereof. In some aspects, the Bulnesia sp.

  • Antimycobacterial Activity of the Ethanolic Extract of the Wood of Bulnesia Sarmientoi Lorentz Ex
    ANTIMYCOBACTERIAL ACTIVITY OF THE ETHANOLIC EXTRACT OF THE WOOD OF BULNESIA SARMIENTOI LORENTZ EX. GRISEB MICKEL R. HIEBERT,A MARÍA EUGENIA FLORES-GIUBI,A JAVIER E. BARUA,A GLORIA M. MOLINA-SALINAS,B ESTEBAN A. FERRO,A NELSON L. ALVARENGAA* (Received June 2012; Accepted August 2012) ABSTRACT In this work the in vitro antimycobacterial activity of the ethanolic extract obtained from the wood of Bulnesia sarmientoi Lorentz ex. Griseb and its chemical compo- sition were studied. The preliminary phytochemical analysis of the extract showed the presence of steroids and/or triterpenes and tannins, and a GC/MS fingerprint analysis identified guaiol and bulnesol as main volatile components of the extract, based on their retention index and the comparison of their mass spectra with those contained in NIST libraries. The extract showed activity against Mycobacterium tu- berculosis H37Rv strain with a minimal inhibitory concentration (MIC) of 50 µg/mL, using the microplate Alamar Blue assay. These results suggest that the extract could be a source of antimicrobial substances against M. tuberculosis. www.relaquim.com Keywords: Bulnesia sarmientoi, antimycobacterial, Alamar Blue, Mycobacterium tuberculosis H37Rv, GC/MS.

Speiser • So¨nke Johnsen Received: 22 October 2012 / Accepted: 28 May 2013 Ó Springer Science+Business Media Dordrecht 2013 Abstract Private communication may benefit signalers by reducing the costs imposed by potential eavesdroppers such as parasites, predators, prey, or rivals. It is likely that private communication channels are influenced by the evolution of signalers, intended receivers, and potential eavesdroppers, but most studies only examine how private communication benefits signalers. Here, we address this shortcoming by examining visual private com- munication from a potential eavesdropper’s perspective. Specifically, we ask if a signaler would face fitness consequences if a potential eavesdropper could detect its signal more clearly. By integrating studies on private communication with those on the evolution of vision, we suggest that published studies find few taxon-based constraints that could keep potential eavesdroppers from detecting most hypothesized forms of visual private com- munication. However, we find that private signals may persist over evolutionary time if the benefits of detecting a particular signal do not outweigh the functional costs a potential eavesdropper would suffer from evolving the ability to detect it. We also suggest that all undetectable signals are not necessarily private signals: potential eavesdroppers may not benefit from detecting a signal if it co-occurs with signals in other more detectable sensory modalities. In future work, we suggest that researchers consider how the evolution of potential eavesdroppers’ sensory systems influences private communication.

  • Changes to CITES Species Listings
    NOTICE TO THE WILDLIFE IMPORT/EXPORT COMMUNITY December 21, 2016 Subject: Changes to CITES Species Listings Background: Party countries of the Convention on International Trade in Endangered Species (CITES) meet approximately every two years for a Conference of the Parties. During these meetings, countries review and vote on amendments to the listings of protected species in CITES Appendix I and Appendix II. Such amendments become effective 90 days after the last day of the meeting unless Party countries agree to delay implementation. The most recent Conference of the Parties (CoP 17) was held in Johannesburg, South Africa, September 24 – October 4, 2016. Action: Except as noted below, the amendments to CITES Appendices I and II that were adopted at CoP 17, will be effective on January 2, 2017. Any specimens of these species imported into, or exported from, the United States on or after January 2, 2017 will require CITES documentation as specified under the amended listings. The import, export, or re-export of shipments of these species that are accompanied by CITES documents reflecting a pre-January 2 listing status or that lack CITES documents because no listing was previously in effect must be completed by midnight (local time at the point of import/export) on January 1, 2017. Importers and exporters can find the official revised CITES appendices on the CITES website. Species Added to Appendix I . Abronia anzuetoi (Alligator lizard) . Abronia campbelli (Alligator lizard) . Abronia fimbriata (Alligator lizard) . Abronia frosti (Alligator lizard) . Abronia meledona (Alligator lizard) . Cnemaspis psychedelica (Psychedelic rock gecko) .

Half a century ago, the state of Hawai’i introduced the Bluestripe Snapper, Lutjanus kasmira, to O’ahu for fisheries enhancement. Today, this species shares an intestinal nematode parasite, Spirocamallanus istiblenni, with native Hawaiian fishes, raising the possibility that the introduced fish carried a parasite that has since spread to naı¨ve local hosts. Here, we employ a multidisciplinary approach, combining molecular, historical, and ecological data to confirm the alien status of S.

Phytomyza linguae Lundqvist, 1947 is recorded as new to Finland. Keywords Checklist, Finland, Diptera, biodiversity, faunistics Introduction The Agromyzidae are called the leaf-miner or leaf-mining flies and not without reason, although a substantial fraction of the species feed as larvae on other parts of living plants. While Agromyzidae is traditionally placed in the superfamily Opomyzoidea, its exact relationships with other acalyptrate Diptera are poorly understood (see for example Winkler et al. 2010). Two subfamilies are recognised within the leaf-mining flies: Agromyzinae and Phytomyzinae. Both are now recognised as natural groups (Dempewolf 2005, Scheffer et al. 2007). Unfortunately the genera are not as well defined: at least Ophiomyia, Phy- toliriomyza and Aulagromyza are paraphyletic in DNA sequence analyses (see Scheffer et al.
