Distribution and importance of the pine processionary moth winter nests Thaumetopoea pityocampa (Denis & Schiffermüller) (Lepidoptera: Notodontidae) in the forests cedar of the National Park of Chréa (Algeria).

Genetic variations, if any, in Musa accuminata exposed to Humic acid ; Coal extracted Humic acid (CHA), Biochar Humic acid (BHA) and Commercially available Keradix (KHA) was evaluated using Random amplified polymorphic DNA (RAPD), Simple Sequence Repeat (SSR) and inter simple sequence repeat (ISSR). In this study tissue culture of Musa accuminata enhanced with various concentrations ranging from 0.1 – 0.5% of Humic acid was carried out in MS medium. The isolated DNA amplified with 2 ISSR, 2 SSR and 2 RAPD primers. The PCR based markers such as RAPD and ISSR were useful techniques for detection of variation atgenetic level. The present protocol used for large scale production of Humic acid enhanced Musa accuminata produce genetically stable plants and was proved that it can be used without any problem.
