The present study was conducted to determine the comparative resistance of ten genotypes of conventional and transgenic cotton was studied under field conditions. The results revealed that infestation of spotted bollworm was high on squares, flowers and bolls of FH-207. The infestation of pink bollworm was high on CIM-2015 followed by PKR-101, CIM-554, FH-207 and CRSM-07.The infestation on squares and flowers of CIM-554 was significantly high followed by PKR-101, CRSM-07, CIM-2015 and FH-207. Overall infestation of bollworm complex was found to be high in CIM-554, CIM-2015 and FH-207 as compared to other transgenic and conventional cott0n genotypes. However, BT-05, SITARA-08 and FH-133/14 emerged as comparatively resistant varieties.

Water is a major limiting factor affecting plant growth, development and yield mainly in arid and semi-arid region where plants are often exposed to periods of water deficit stress which is also known as drought stress (Foyer et al., 1994). Drought and heat stress can cause oxidative stress through the production of reactive oxygen species such as super oxide radicals and hydrogen peroxide. Also the drought, salinity, extreme temperatures and oxidative stress are often interconnected and may induce similar cellular damage. Plant growth and productivity is adversely affected by nature's wrath in the form of various abiotic and biotic stress factors. (Serrano et al., 1999). The effect of water stress in contrast to roots; leaf growth is severely inhibited at the onset of drought. Leaf cell expansion during water stress is regulated by changes in pH and inhibition of growth is mediated by a rapid decrease in extensibility of expanding leaf cell walls.The study was conducted to determine the effect of drought stress on the growth and development of Gampherena globosa. The data recorded for different growth parameters of the plant.

This book describes the Insecticidal activity of essential oils extracted from different citrus varieties, sweet orange, kinnow, bitter orange and grape fruit, at three different concentrations (3%, 6%,12%) was evaluated in the Grain Research Training and Storage Management Laboratory at Department of Entomology, University of Agriculture Faisalabad Pakistan.The Objective of the study was to evalute the insecticidal activity of citrus oils against percent mortality and population buildup of Lesser Grain Borer.The conclusions were withdrawn from the obtained results, maximum mortality was recorded at high concentration.Maximum population build up was recorded in controlled treatment(36.67%), while in treated sample(5.883%). The percent mortality increases with the increased in concentration and the concentration of oils have significant effect on the mortality of Lesser Grain Borer. Population buildup value was found maximum in control treatment than treated but increased in concentration population buildup value was decreased. The results also show that Multan strain are highly susceptible than Vehari strain of Lesser Grain Borer.
