Development and feeding potential of the green lacewingChrysoperla carnea Steph. (Neur. Chrysopidae) on different insect pests of cotton

Results of laboratory experiments revealed that the total development period (egg to adult emergence) of the common green lacewing Chrysoperla carnea lasted for 19.15, 19.35, 19.95, 20.15, 20.60 and 22.50 days when the larvae were fed with Bemisia tabaci, eggs of Corcyra cephalonica, Heliothis armigera, Aphis gossypii, Amrasca biguttula and neonates of Heliothis armigera respectively. Larval development was rapid on eggs of C. cephalonica (8.20 days) and prolonged on neonates of H. armigera (11.10 days). Pupal development period was quicker on B. tabaci and A. biguttula (7.40 days) and prolonged on neonates of H. armigera (8.40 days).During development each larva of C. carnea consumed an average of 732.35 eggs of C. cephalonica, 662.53 eggs of H. armigera, 419,18 A. gossypii, 409.55 neonates of H. armigera 329.70 pupae of B. tabaci and 288.45 nymphs of A. biguttula. In all the cases, the third instar larvae consumed the major portion of the total number consumed (60–80%). The most suitable preys, resulting in rapid development, for C. carnea were pupae of B. tabaci and eggs of C. cephalonica.With 2 tables

Development of ITS sequence based molecular marker to distinguish, Tribulus terrestris L. (Zygophyllaceae) from its adulterants

Tribulus terrestris L. (Zygophyllaceae) is one of the highly traded raw drugs and also used as a stimulative food additive in Europe and USA. While, Ayurvedic Pharmacopoeia of India recognizes T. terrestris as Goksura, Tribulus lanuginosus and T. subramanyamii are also traded by the same name raising issues of quality control. The nuclear ribosomal RNA genes and ITS (internal transcribed spacer) sequence were used to develop species-specific DNA markers. The species-specific markers efficiently amplified 295 bp for T. terrestris (TT1F and TT1R), 300 bp for T. lanuginosus (TL1F and TL1R) and 214 bp for T. subramanyamii (TS1F and TS1R). These DNA markers can be used to distinguish T. terrestris from its adulterants.     

基于分子标记的野生棉遗传关系研究

利用RAPD技术研究了野生棉种间遗传关系。采用45条随机引物获得758个条带,根据UP GMA聚类分析将16个野生棉种分为5组。第1组包括B组染色体的4个棉种,其中异形棉(G.anomalum)与三叶棉(G.triphyllum)相似系数高达0.96。第2组包括瑟伯氏棉(G.thurberi)等7种,长萼棉(G.longicalyx)、比克氏棉(G.bickii)分别单独构成第4,5组,斯特提棉(G.sturtianum)、澳洲棉(G.australe)和细毛棉(G.pilosum)组成第3组。
