Pengelompokan Biotipe Wereng Cokelat Berdasarkan Hasil PCR-RAPD

open access: yesHayati Journal of Biosciences, 2005
Random amplified polymorphic DNA (RAPD) technique was used to differentiate two brown planthopper biotypes, that were multiplied in the greenhouse. Ten selected random decamer RAPD primers produced unique DNA band patterns for each individual brown ...

Levels of genetic polymorphism: marker loci versus quantitative traits [PDF]

open access: yes, 1998
Species are the units used to measure ecological diversity and alleles are the units of genetic diversity. Genetic variation within and among species has been documented most extensively using allozyme electrophoresis.

Dynamical modeling of the control of brown planthoppers by Beauveria bassiana and Cyrtorhinus lividipennis

open access: yesAdvances in Difference Equations, 2019
In this work, the control of brown planthopper, a major pest of rice, when a biological control agent (Cyrtorhinus lividipennis) and a pathogen (Beauveria bassiana) are utilized is investigated mathematically.

Oxalic Acid Inhibits Feeding Behavior of the Brown Planthopper via Binding to Gustatory Receptor Gr23a

open access: yesCells, 2023
Plants produce diverse secondary compounds as natural protection against microbial and insect attack. Most of these compounds, including bitters and acids, are sensed by insect gustatory receptors (Grs).
