The genus Lasinus Sharp, 1874 of the Pselaphodes complex of genera (Pselaphitae: Tyrini: Tyrina) is revised. The three so far known species, Lasinus mandarinus Raffray, 1890, Lasinus monticola Sawada, 1961 and Lasinus spinosus Sharp, 1874 are redescribed. Eight new species, Lasinus sinicus sp. n. from China, Lasinus mikado sp. n., Lasinus yamamotoi sp. n., Lasinus inexpectatus sp. n., Lasinus y...

Eight species of the genera Pselaphodes Westwood and Labomimus Sharp described from 1870 to 1925 are reviewed, six of them are redescribed, with their major diagnostic characters illustrated. Lectotypes are designated for the following names: Pselaphodes antennatus Bryant, 1915, Pselaphodes simplicicornis Champion, 1925, Pselaphodes spinosus Champion, 1925, and Pselaphodes villosus Westwood, 18...

Abstrak. Penghambatan yang disebabkan oleh gulma bisa mengganggu pertumbuhan serta perkembangan tanaman budidaya. Aplikasi herbisida kimia sintetik dalam waktu berkepanjangan cenderung menimbulkan efek negatif, sehingga perlu dicari cara aman bagi lingkungan dengan memanfaatkan senyawa turunan tumbuhan (alelokimia) sebagai bioherbisida. Babadotan adalah berpotensi Penelitian ini memiliki tujuan...

Abstrak : Penggunaan herbisida umumnya dilakukan sebagai langkah praktis dalam mengendalikan gulma. Namun, penggunaan secara terus menerus dapat menyebabkan efek negatif terhadap lingkungan. Adapun tujuan dari penelitian ini untuk menguji efektivitas senyawa bioherbisida ekstrak n-heksana babadotan (Ageratum conyzoides L.) subfraksi B pada beberapa konsentrasi pertumbuhan gulma bayam duri (Amar...

The objective of this investigation was to evaluate the possibility of substituting Amaranthus pigments for nitrates in the of manufacture pork sausage. Five treatments of pork sausages (5% fat) with two levels of sodium nitrite (0 and 0.015%), or three levels (0.1%, 0.2% and 0.3%) of pigments extracted from red Amaranthus were produced. The addition of Amaranthus pigments resulted in the signi...

Seed of Amaranthus alus L. develop an enhanced sensitivity to the farred absorbing form of phytochrome after prolonged imbibition at temperatures >32 degrees C. The enhanced sensitivity developed at 40 degrees C could be reversed by subsequent treatment at 20 degrees C and similarly reestablished by repeating a 40 degrees C treatment. It is concluded that relative sensitivity to the far-red abs...

Thermostable direct hemolysin-producing strain of Vibrio parahaemolyticus was not detected from the alimentary tract of 7 neritid gastropods including Clithon retropictus at 9 estuaries of Southwest Islands in Japan in the present study. The strain has been detected from C. retropictus at 2 estuaries facing The Sea of Japan but not at 2 estuaries facing The Seto Inland Sea and The Pacific Ocean...

East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compar...
