New Pest Response Guidelines United States Department of New Pest Response Agriculture Animal and Plant Health Guidelines Inspection Service Tropical Terrestrial Gastropods Cooperating State Departments of Agriculture The U.S. Department of Agriculture (USDA) prohibits discrimination in all its programs and activities on the basis of race, color, national origin, age, disability, and where applicable, sex, marital status, familial status, parental status, religion, sexual orientation, genetic information, political beliefs, reprisal, or because all or part of any individuals income is derived from any public assistance program. (Not all prohibited bases apply to all programs). Persons with disabilities who require alternative means for communication o program information (Braille, large print, audiotape, etc.) should contact USDA TARGET Center at (202) 720-2600 (voice and TDD). To file a complaint of discrimination, write to USDA, Director, Office of Civil Rights, 1400 Independence Avenue, SW., Washington, DC 20250-9410, or call (800) 795-3272 (voice) or (202) 720-6382 (TDD). USDA is an equal opportunity provider and employer. This document is not intended to be complete and exhaustive. It provides a foundation based upon available literature to assist in the development of appropriate and relevant regulatory activities. Some key publications were not available at the time of writing, and not all specialists and members of the research community were consulted in the preparation of this document. References to commercial suppliers or products should not be construed as an endorsement of the company or product by the USDA. All uses of pesticides must be registered or approved by appropriate Federal, State, and/or Tribal agencies before they can be applied. The information provided on pesticide labels may not reflect all of the actual information, including precautions and instructions for use, which you are required to follow in your specific State or locality. It is the responsibility of persons intending to use a pesticide to read and abide by the label, including labeling approved for the particular State or locality in which the chemical is to be used, and to comply with all Federal, State, Tribal, and local laws and regulations relating to the use of the pesticide. APHIS program staffs are responsible for their compliance with applicable environmental regulations. CAUTION: Pesticides can be injurious to humans, domestic animals, desirable plants, and fish or other wildlife—if they are not handled or applied properly. Use all pesticides selectively and carefully. Follow recommended practices for the disposal of surplus pesticides and pesticide containers.

Krishi Mandi, New Palsi Road, Jodhpur-342 005, Rajasthan, India INTRODUctION More than 1500 species of land mollusc are recorded from India. Out of these, twelve species viz. Achatina fulica Bowdich, Ariophanla bajadera (Pfeiffer), Ariophanta ligulata Ferrussac, Ariophanta solata (Benson), Bensonia monticola Hutton, Cryptozona belangiri Deshayes, Cryptozona (Nilgiria) semiru~ata (Seck.), Cryptozona (Xestina) bistrialis Beck., Macrochlamys indica (Godwin-Austen), Opeas gracile (Hutton), Zootecus insularis (Ehrenberg) and Mariaella dussumieri (Gray) are known to cause damage to agricultural, horticultural and plantation crops in India (Raut & Ghosh, 1984; Srivastava, 1992 and Subba Rao, 1975). So far, only two pestiferous land moliusc Opeas gracile (Hutton) and Zootecus insularis (Ehrenberg) are reported from Rajasthan (Subba Rao & Mitra, 1979 and Raut & Ghosh, 1984). Laevicaulis alte (Ferussac) is reported from Udaipur, Rajasthan but not as a pest (Ray & Mukherjee, 1963). The present paper reports for the first time, two more pestiferous land mollusc - Laevicaulis alte (Ferussac) and Macrochlamys indica (Godwin-Austen), as severe pests of neem seedlings in forest nurseries of Rajasthan along with new distributional records.

    Veronicella spp.* *In April 2013, the family Veronicellidae, a target on the 2013 and 2014 AHP Prioritized Pest Lists, was broken down into six genera of concern, including Veronicella spp. Information in the datasheet may be at the family, genus, or species level. Information for specific species within the genus is included when known and relevant; other species may occur in the genus and are still reportable at the genus level. Portions of this document were taken Figure 1.

Pest Description Veronicellidae are anatomically distinct from many other terrestrial slugs in that they have a posterior anus, eyes on contractile tentacles, and no pulmonate lung. The sensory tentacles are bilobed. This family also lacks a mantel cavity (Runham and Hunter, 1970). Although this family is fairly easy to tell apart from others, species within this family can be difficult to distinguish due to similar morphology between species and multiple color variations within a single species.

    EENY-494 Terrestrial Slugs of Florida (Gastropoda: Stylommatophora)1 John L. Capinera2 Introduction Florida has only a few terrestrial slug species that are native (indigenous), but some non-native (nonindigenous) species have successfully established here. Many interceptions of slugs are made by quarantine inspectors (Robinson 1999), including species not yet found in the United States or restricted to areas of North America other than Florida. In addition to the many potential invasive slugs originating in temperate climates such as Europe, the traditional source of invasive molluscs for the US, Florida is also quite susceptible to invasion by slugs from warmer climates. Indeed, most of the invaders that have established here are warm-weather or tropical species. Following is a discus- sion of the situation in Florida, including problems with Figure 1. Lateral view of slug showing the breathing pore (pneumostome) open. When closed, the pore can be difficult to locate. slug identification and taxonomy, as well as the behavior, Note that there are two pairs of tentacles, with the larger, upper pair ecology, and management of slugs. bearing visual organs.

Slugs also reduce water loss by opening their internal shell and a few have a greatly reduced external breathing pore (pneumostome) only periodically instead of shell). The slug life-form (with a reduced or invisible shell) having it open continuously. Slugs produce mucus (slime), has evolved a number of times in different snail families, which allows them to adhere to the substrate and provides but this shell-free body form has imparted similar behavior some protection against abrasion, but some mucus also and physiology in all species of slugs.

    Sarasinula spp.* *In April 2013, the family Veronicellidae, a target on the 2013 and 2014 AHP Prioritized Pest Lists, was broken down into six genera of concern, including Sarasinula spp. Information in the datasheet may be at the family, genus, or species level. Information for specific species within the genus is included when known and relevant; other species may occur in the genus and are still reportable at the genus level. Portions of this document were taken directly from the New Pest Response Guidelines for Tropical Terrestrial Gastropods (USDA-APHIS, 2010a). *Information for specific species within the genus is included when known and relevant. Other species may occur in the genus and are still reportable at the genus level. Figure 1.
