Os gastrópodes terrestres enfrentam um grave problema, além das alterações nos ambientes naturais, sofrem a competição direta com espécies exóticas e pela introdução demasiada dessas espécies. Nesse sentido, este estudo teve como objetivo realizar um inventário das espécies de gastrópodes terrestres em União da Vitória, extremo sul do Paraná, com a finalidade de fornecer informações para análises ecológicas e taxonômicas em uma área urbana. Na zona urbana central foram amostradas 20 áreas domiciliares, durante os meses de junho, setembro e dezembro de 2019 e março de 2020. Em cada local, os gastrópodes foram coletados usando três quadrantes com área amostral de 5 m2. As amostragens envolveram padronização de esforço amostral através do método de coleta ativa manual. Um total de 10 famílias, 15 espécies e 1.835 espécimes foram registrados na biocenose estudada. As espécies Leptinaria sp., Happia insularis, Belocaulus angustipes e Succinea aff. burmeisteri foram encontradas em apenas uma coleta. As espécies dominantes foram Bradybaena similaris (70,3%, n = 1.290), Phyllocaulis soleiformis (10,7%, n = 196) e Achatina fulica (7,85%, n = 144) totalizando 88,85 % dos espécimes coletados. As espécies constantes foram Bradybaena similaris, Achatina fulica, Cornu aspersum, Limax maximus, Limacus flavus, Phyllocaulis soleiformis e Meghimatium pictum. Entre as espécies encontradas, sete são espécies exóticas introduzidas. A utilização de uma metodologia de coleta adequada para ambiente urbano possibilitou a amostragem de espécimes que apresentam preferência por hortas, jardins, plantações, terrenos baldios e solo. De uma maneira geral, a fauna de moluscos foi subrepresentada, entretanto, a riqueza tanto das espécies exóticas quanto as espécies nativas foi equivalente, o que é esperado em centros urbanos.

Tanaman dalugha (Cyrtosperma merkusii (Hassk.) Schott) merupakan tanaman endemik di Propinsi Sulawesi Utara yang perlu dilindungi dari serangan organisme pengganggu tumbuhan. Karakter morfologi dan Identifikasi hama sangat perlu untuk kajian ilmiah tentang budidaya tanaman endemik dalugha sebagai sumber pangan lokal di Sulawesi Utara. Penelitian ini bertujuan untuk mengetahui karakter morfologi dan identifikasi hama pada tanaman dalugha. Lokasi penelitian di desa Moronge, Kecamatan Moronge, Kabupaten Kepulauan Talaud. Penelitian ini menggunakan metode deskriptif kualitatif, pengambilan sampel hama ditentukan dengan teknik purposive sampling. Karakter morfologi dan identifikasi hama dilakukan dengan menggunakan buku kunci determinasi serangga hama dan aplikasi google lens dengan tingkat akurasi pengenalan spesies hewan yang tepat.

Schott) in Talaud Islands District, North Sulawesi Province ABSTRACTDalugha plants (Cyrtosperma merkusii (Hassk.) Schott) are endemic plants in North Sulawesi Province which need to be protected from attack by plant-disturbing organisms. Morphological characters and identification of pests are very necessary for scientific studies on the cultivation of endemic plants of dalugha as a local food source in North Sulawesi. This study aims to determine the morphological characters and identification of pests in dalugha plants. The research location is in Moronge Village, Moronge District, Talaud Islands Regency. This study used a qualitative descriptive method, the sampling of pests was determined by purposive sampling technique. Morphological characters and identification of pests were carried out using the key book for insect pest determination and the Google Lens application with an accurate level of recognition of animal species. The results showed that there was a diversity of pests in Dalugha plants which were divided into three classes: Gastropod class namely Bekicot (Achatina fulica), Keong semak (Bradybaena similaris), Siput hijau (Rhinocochlis nasuta), Siput pita (Caracolus marginella), Siput kebun (Cornu aspersum), and Sumpil (Subulina octona); Class Insects are Belalang hijau (Oxya servile), Jangkrik semak (Tettigonia caudate), Kumbang daun (Asphaera lustrans), Kepik kaki daun tumbuhan (Leptoglossus australis), Kutu kebul (Bemisia tabaci), Semut kebun hitam (Lasius niger), Ulat tanduk (Theretra oldenlandiae), Kecoa (Periplaneta americana L.), and Kecoa surinam (Pycnoscelus surinamensis) and Oligochaeta class namely Cacing tanah (Lumbricus rubellus).Keywords: dalugha; identification; morphology; North Sulawesi; pest

The cells which are described in this study surround the salivary nerve of the terrestrial mollusc, Limax maximus. The salivary system of Limax consists of bilateral glands, ducts, and nerves. The salivary nerves originate at the buccal ganglia, which are situated on the posterior face of the buccal mass, and run along the salivary duct to the gland. The salivary nerve branches several times near the gland, and eventually sends processes into the gland.The pore cells begin to appear at the first large branch point of the salivary nerve, near the gland (Figure 1). They follow the nerve distally and eventually accompany the nerve branches into the gland tissue. The cells are 20-50 microns in diameter and contain very small nuclei (1-5 microns) (Figure 2).The cytoplasm of the pore cells is segregated into a storage area of glycogen and an organelle region located in a band around the cell periphery (Figure 3).

Abstract Background Metastrongyloid parasites Angiostrongylus vasorum and Crenosoma vulpis infect wild and domestic canids and are important pathogens in dogs. Recent studies indicate that gastropod intermediate hosts infected with various metastrongyloids spontaneously shed infective third-stage larvae (L3) into the environment via feces and mucus under laboratory conditions. Shed L3 retain motility up to 120 days, but whether they retain infectivity was unknown. Methods To assess the infectivity of shed L3, the heart/lungs of six red foxes (Vulpes vulpes) were obtained from trappers in Newfoundland, Canada. Lungs were examined for first-stage larvae (L1) by the Baermann technique. A high number of viable A. vasorum L1 and a low number of C. vulpis L1 were recovered from one fox; these were used to infect naïve laboratory-raised Limax maximus. L3 recovered from slugs by artificial digestion were fed to two naïve purpose-bred research beagles (100 L3/dog). L1 shed by these two dogs was used to infect 546 L. maximus (2000–10,000 L1/slug). L3 shedding was induced by anesthetizing slugs in soda water and transferring them into warm (45 °C) tap water for at least 8 h. Shed L3 recovered from slugs were aliquoted on romaine lettuce in six-well tissue culture plates (80–500 L3/well) and stored at 16 °C/75% relative humidity. Four naïve research beagles were then exposed to 100 L3/dog from larvae stored for 0, 2, 4, or 8 weeks, respectively, after shedding. Results All four dogs began shedding C. vulpis L1 by 26–36 days post-infection (PI). All four dogs began shedding A. vasorum L1 by 50 days PI. Conclusions L3 infectivity for the definitive host was retained in both metastrongyloids, indicating the potential for natural infection in dogs through exposure from environmental contamination. As an additional exposure route, eating or licking plant or other material(s) contaminated with metastrongyloid L3 could dramatically increase the number of dogs at risk of infection from these parasites.
