Item Metadata only Spermatogenesis and chromatin condensation in the male germ cells of the giant african snail, achatina fulica bowdich(Mahidol University. Mahidol University Library and Knowledge Center, 2000) Viriya Pankao; Chaitip Wanichanon; Prasert Sobhon; Maleeya Kruatrachue; Prapee SretarugsaItem Metadata only Assessing the efficacy of soapberry (Sapindus rarak) crude extract for controlling giant African land snail (Lissachatina fulica)(2022-01-01) Koysap L.; Ruangsittichai J.; Ampawong S.; Kongkiatpaiboon S.; Worakhunpiset S.; Thaenkham U.; Chusongsang Y.; Lv Z.; Mongkolthanawat S.; Limpanont Y.; Mahidol UniversityThe giant African land snail (Lissachatina fulica) is a major pest that damages agricultural products and the environment, along with raising public health concerns. Although various methods have been applied to control these invasive snails... extract and to develop a molluscicide from it to control the giant African land snail. The soapberry (Sapindus rarak) crude extract exerted molluscicidal effects against L. fulica within 4 h. Soapberry concentration of 30% caused snail mortality of nearlyPublication Metadata only Effects of parasitism and stress on hemolymph protein of the African giant snail, Achatina fulica(1978-06-01) Chariya Ratanarat Brockelman; Mahidol UniversityEffects of parasitism and stress on the protein concentration of hemolymph have been investigated using the rat lungworm Angiostrongylus cantonensis in the snail host Achatina fulica. The normal hemolymph protein concentration, averaging 1.77 g/100... ml in noninfected snails, did not show any reduction when the hosts were infected with third stage larvae. When the infected snails were bled repeatedly, protein concentration showed a significant decrease by 0.6 g/100 ml. Starved, infected snailsPublication Metadata only Carbohydrate reserves and hemolymph sugars of the African giant snail, Achatina fulica in relation to parasitic infection and starvation(1980-10-01) Chariya R. Brockelman; Paiboon Sithithavorn; Mahidol UniversityIn the snail, Achatina fulica, parasitized by the rat lungworm Angiostrongylus cantonensis, levels of carbohydrate in hemolymph and digestive glands were determined. The normal level of hemolymph glucose of 11.7 mg% dropped to 4.25 mg...% in the infected snails, a significant difference after only one week of infection. The level of total reducing sugar in the hemolymph also decreased significantly (12.3 mg% to 3.6 mg%) in this period. Later on, the snails were capable of adapting themselvesItem Metadata only Study on the structure and function of neuroendocrine organs in giant African snail, Achatina fulica(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Viyada Seehabutr; Jittipan Chavadej; Suchart Upatham; Prapee Sretarugsa; Prasert Sobhon; Maleeya Kruatrachueshape. The numbers of giant cells in each ganglion vary; there are 16, 14, 8, 6, 4 and 4 giant cells in the pedal, parietal, cerebral, visceral, pleural and buccal ganglia of adult snail, respectively. The ultrastructures of the ordinary neurons... organized occurred in the newly-hatched snails. During development, all the ganglia and the number of nerve cells in the ganglia increase with increasing age of snails. In addition, the number and size of large cells and giant cells are also increasedPublication Metadata only Genetic characterization of Angiostrongylus larvae and their intermediate host, Achatina fulica, in Thailand(2019-01-01) Abdulhakam Dumidae; Pichamon Janthu; Chanakan Subkrasae; Paron Dekumyoy; Aunchalee Thanwisai; Apichat Vitta; Naresuan University; Mahidol Universityare credited. Angiostrongyliasis is a parasitic disease caused by nematodes of the genus Angiostrongylus. Distribution of this worm corresponds to the dispersal of its main intermediate host, the giant African land snail Achatina fulica. Genetic... characterization can help identify parasitic pathogens and control the spreading of disease. The present study describes infection of A. fulica by Angiostrongylus, and provides a genetic outlook based on sequencing of specific regions. We collected 343 land snails
