...f insect pests and their predators in sunflower ecosystem. The data revealed that B. tabaci and Empoasca spp were present throughout the cropping season. Their average maximum populations (5.65 and 3.20 individuals / leaf) were recorded during 3-week of May 2009. Aphis gossypii was recorded during the month of March and its maximum population (28.3 individuals / leaf) was observed during 2-week of March 2009. Likewise, Nysius inconspicuous was observed during ...

Keeping in view the limited work on these important beetles, an extensive faunal survey was conducted in the district Sargodha (32°05’02’’ N and 72°40’18’’ E), Pakistan to assess the species richness and distribution of coccin...

We studied the burrow architecture (length, internal dimensions, fractal dimension of tunnel systems, number of nesting chambers and surface holes) by excavating the tunnels of 24 burrow systems of the plateau pika (Ochotona curzoniae). Pikas have two types of burrow systems, namely temporary and permanent burrows. The num...

...ue natural parasites and predators are used to check pest growth instead of pesticides which reduces ecological and health damage. Pesticides are used at the last resort in IMP method so it reduces the cost of production and increases the farmers’ profit. However, concerns about production may hinder widespread adoption of this technology by farmers. The aim of the study is to evaluate economic feasibility of IPM method in Punjab. The study consisted of ...

Life tables of S. fallax were constructed at 20°C, 24°C, 28°C and rhythmically fluctuating temperature regimes from 16°C to 24°C and 24°C to 32°C. Studies were carried out describing survival, reproduction and development of S fallax. Survival was positively temperature dependent. Sex ratio was not affected by constant temperatures from 20 to 28°C; however this rat...

But the application of insecticides in field to manage aphids cause impairment of several key biological traits of the exposed coccinellids through physiological and behavioral effects. It is crucial to understand the effects of insecticides on the coccinellids. The current research was aimed at determining the intra-guild predation (IGP) of different life stages combinations of Coccinella...

Studies were carried out to evaluate the suitability of three aphid species on the pre-imaginal development of three species of green lacewings. Developmental stages of three different species of green lacewings, Chrysoperla nipponensis, Plesiochrysa ramburi and Apertochrysa sp. were provided with three different prey species, Aphis craccivo...
