Abstract

A new family, Acephalidae n. fam. and a new genus Acephalus n. gen. are proposed in this communication to accommodate a new septate gregarine (Apicomplexa : Conoidasida) Acephalus sundarbanensis n. sp. collected from the midgut of an orthopteran insect host, Euconocephalus incertus from Sundarban region of West Bengal, India. The characteristics of this new family and its affinity with the closely related families are discussed.

Abstract

The paddy plants attacked by yellow stem boier at flowering stage produce ears devoid of grain, known as the 'white ears'. The 'white ears" may also be caused by the neck blast, a fungal disease. During the Boro season of paddy (varieties : I. R. - 36, I. E. T. - 4786) surveys were conducted at Basanti Block of Sundarban region of West Bengal, India from December 2004 to April 2005 to find out the differences between two similar symptoms of white ears, caused by yellow stem bores and by neck blasts for facilitating their control measures. Data were collected at an interval of 7 days. Nature of damage was recorded during each survey trip. During investigation, it has been observed that about 20% of white ears were caused by yellow stem borer and about 80% of white ears by neck blast.

Abstract

During the Aman season of paddy from July, 2005 to December, 2005 surveys were conducted at Basanti Block of Sundarban region of West Bengal, India. Data were collected at an interval of 7 days and the nature of damage was recorded during each survey trip. It has been observed that Patnai and Diidhsar varieties of paddy are mostly affected with false smut due to heavy rainfall from 18.10.05 to 24.10.05. Other varieties like Rupshal, Ruglmshal are less affected. These varieties are local and photo sensitive. Their flowering stage is usually from 3rd week of October to 1st week of November.
