Population dynamics of major insect pests and their natural enemies on cabbage under new alluvial zone of West Bengal
...sons with 11.67 and 9.67 coccinellids/ 5plants, respectively. Both maximum and minimum temperature had major role to build up the population of diamond back moth, C. plutellae and coccinellids beetle while aphid population was enhanced only by maximum temperature. Relative humidity and rainfall had negative influence on pests and natural enemies during the study period.

Biodiversity and Species Distribution of Coccinellids (Coccinellidae: Coleoptera) in District Sargodha (Punjab), Pakistan
Kanwer Shahzad Ahmed1, Muhammad Zeeshan Majeed1,*, Muhammad Ather Rafi2, Fatima Sellami3 and Muhammad Afzal1
.... Among 6,000 species of coccinellids described worldwide, only 75 species have been reported from Pakistan so far. 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 coccinellid beetles in seven selected regions (Bhera, Bhalwal, Kot Momin, Sahiwal, S...

...al 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 septempunctata and Coccinella transversalis in the presence and absence of prey and the impact of sublethal concentrations ...

Adverse Effect of Sublethal Concentrations of Insecticides on the Biological Parameters and Functional Response of Predatory Beetle Coccinella septempunctata (Coleoptera: Coccinellidae) of Brassica Aphid
...ignificantly reduced the coccinellids larval weight. Type II response was shown by larvae of C. septempunctata in control treatment. Larval coccinellids showed type II functional response after feeding on the brassica aphids (Brevicoryne brassicae) treated with thiamethoxam, lambda-cyhalothrin and cypermethrin, while imidacloprid, profenophos and chlorpyrifos treated aphids altered the functional response of larval
Multi-gene Phylogenetic Analysis and Genetic Diversity of Discrete Elytral Color Phenotypes in Menochilus sexmaculatus (Coleoptera: Coccinellidae)

...screte color patterns in coccinellids is still poorly known. Here, we present a comprehensive genetic diversity analyses and phylogenetic relationships within seventeen different phenotypes of elytral color patterns in Menochilus sexmaculatus based on two mitochondrial genes, cytochrome oxidase subunit I (COI) and II (COII), and two nuclear genes, carbamoyl phosphate synthetase (CAD) and histone subunit 3 (H3). Results indicated the average genetic distance wa...
Irrigation Stress to Wheat at Sensitive Growth Stages: Tri-trophic Effects and Implications for Aphid Control

Shahbaz Ahmed1, Mubeen Ahmad1, Muhammad Razaq1* and Farhan Mahmood Shah1,2*

...undant aphid species and coccinellids, the most abundant predators. S. graminum was least on unstressed or tillering stressed wheatbut was the most on wheat stressed at booting, heading, and grain formation stages. Irrigation stress reduced chlorophyll contents (5-25%) and wheat yield (kg/ha) (6-31%) when compared with unstressed wheat. The irrigation stress changed coccinellid abundance and predator-prey ratio. Altered plant physiology and a weaken plant defe...

Biodiversity, Seasonal Abundance, and Population Dynamics Assessment of Coccinellidae (Coleoptera) from Maize Crops

Naveed Akhtar, Hafiz Muhammad Tahir*, Azizullah, Aamir Ali

...and seasonal dynamics of coccinellids in two major maize-growing districts of the Punjab province, i.e., Kasur and Lahore, in 2018-2019. The coccinellids were collected from February to June during both cropping seasons. Visual counting, handpicking, sweep nets, sticky traps, and pitfall traps were employed for collection of specimens fortnightly. In aggregate, 10637 specimens representing 21 species, 16 genera, and 3 subfam...
