Mustard (Brassica juncea) variety BARI Shorisha-11 was cultivated during September 2016 to March 2017 in Gazipur, Bangladesh to find out the population dynamics of aphid and its infestation level on mustard. The aphid Lipaphis erysimi (Homoptera: Aphididae) was abundant in the field and caused infestation. The population of aphid in the mustard field showed fluctuation and reached to the peak at 22 December which was 289 per plant. Inflorescence had significantly higher level of infestation compared to individual siliqua and leaf. The daily mean temperature had significant negative, light intensity had insignificant negative and relative humidity had insignificant positive correlation with the abundance of aphid. The multiple linear regression analysis showed that the weather parameters namely temperature, light intensity and relative humidity individually as well as combindly contributed on the abundance of aphid, but the temperature had greater effect than other factors.Bangladesh J.

Perceptual Matching

The study was designed to determine the predictive validity of 5 kinesio-perceptual (KP) items (dynamic equilibrium, reaction time, agility, static equilibrium, and KP matching) contained in a test battery (KPT) administered to 120 institutionalized retarded children, chronological ages (CA) 8 to 20 yr. When multiple linear regression analysis was used to predict scores on the Wechsler Intelligence Scale for Children (IQ) the multiple correlation was .75 ( R2 = .57, p = .001). Knowledge of CA and sex added only 1% to the total amount of IQ variance accounted for. A brief discussion of the conflict between the goals of developmental validation and prediction of intellective criteria was also presented.
