  • SEASONAL OCCURRENCE OF HONEY BEES IN CORIANDER
    Mandar Vijay Thakur, Neeraj Kumar, Gouri Shankar Giri, Raj Dev Verma, Sujal Suhas Munj
    Indian Journal of Entomology, 2025
    A multi-location trail was carried out at the Beekeeping Unit, TCA, Dholi (Muzaffarpur District, India) and University Apiary, RPCAU, Pusa (Samastipur District, India) during Rabi 2021-22 on Rajendra Dhania-2 variety of coriander. Spatial distribution of bee species in Pusa and Dholi showed that occurance of Italian bee Apis mellifera (F) was comparatively higher at Pusa (19.03± 6.29/ m2 / 10 min) as compared to Dholi (16.56± 5.47/ m2 / 10 min). Other species of honey bees viz. Indian hive bee, Apis cerana (F), rock bee Apis dorsata (F) and little bee Apis florea (F) were more abundant in Dholi as compared to Pusa. Maximum (number of bee/ m2 / 10 min) of Apis mellifera (24.02, 27.60), Apis dorsata (16.88, 14.89), Apis cerana (14.55, 11.64) and Apis florea (10.47, 8.63) were observed at 13:00, 15:00, 11:00 and 09:00 at Dholi and Pusa, respectively. The underlying factors of this distribution were identified as body size and dietary overlap. This study highlights the complexity of interactions between Apis spp. genus and shows how factors like body size and diet influence their distribution patterns.
  • Foraging behaviour of domestic bee species on coriander
    Mandar Vijay Thakur, Neeraj Kumar, Gouri Shankar Giri, Raj Dev Verma, Sujal Suhas Munj
    Journal of Entomological Research, 2024
    AbstractThe research aimed to assess the distribution, foraging behavior of honey bee species, and their impact on yield. Duration of foraging was maximum in Apis mellifera than Apis cerana. Initiation time of foraging for Apis mellifera was 6:49 AM which was earlier than Apis cerana (07:01 PM) and activity ceased at 17:12 PM. Foraging speed was maximum in Apis mellifera (6.04 sec.) followed by Apis cerana (4.30 sec.). Foraging rate was higher in Apis cerana (10.92 flowers) than Apis mellifera (8.52 flowers). Application of insecticide (Imidacloprid 17.8 % SL) completely ceased the activity of honey bee species on flowers of coriander for 3 days. Effect of insecticide on foraging behaviour was observed for 7-8 days in domestic bee species.
  • Population dynamics of insect pest associated with Barnyard millet in Bihar
    Gouri Shankar Giri, Kaushal Kishor, Sweta Mishra, Neeraj Kumar
    Journal of Entomological Research, 2024
    AbstractDuring the period of investigation, the crop at its early growth period was found to be infested by shoot fly whereas the infestation of ear head bug and stem borer was recorded in late vegetative stage to maturity stage. The infestation of grasshopper was initiated during early vegetative stage and continued up to maturity stage. It was observed that per cent dead heart caused by shoot fly and stem borer had a negative and significant relation with the morning relative humidity whereas per cent dead heart caused by stem borer had a negative and significant relation with minimum temperature and evening relative humidity. The population of grass hopper had a negative and significant relation with the morning relative humidity.
  • Spatial and temporal distribution of domestic and wild bee species in mustard with special concern of competitive displacement
    Raj Dev Verma, Gouri Shankar Giri, Neeraj Kumar, Mandar Vijay Thakur, Lohit Tudu
    Journal of Entomological Research, 2024
    AbstractMean population of Apis mellifera was slightly higher in Pusa as compared to Dholi, whereas population of Apis cerana, Apis florea and Apis dorsata were slightly higher in Dholi. Wild bee species were more abundant in Dholi due to the diverse cropping pattern and availability of forest trees. The population change was non-significant between these two places at different interval of the day and different dates. Same climatic condition was the main reason behind non-significant difference. Slight fluctuation in population of species was due to the diverse forage at both places. Population of Apis mellifera and Apis dorsata was higher during afternoon and late afternoon, respectively. Apis florea and Apis cerana were abundant during morning and late morning, respectively. Due to smaller size, Apis florea and Apis cerana got easy entry in partial opened flowers in morning which was main reason behind their abundance in morning. Population peak of bee species at different dates and time intervals was due to competitive displacement between the bee species at both the places. Influence of weather parameters on population of Apis mellifera and Apis dorsata was significant. Population of these two species increased with increase in temperature while population reduced with increasing relative humidity, whereas Apis florea and Apis cerana showed exactly opposite pattern.
  • Influence of weather parameters on the incidence of insect pests and natural enemies associated with lentil and field pea in Bihar
    Gouri Shankar Giri, Neeraj Kumar, Kaushal Kishore, R. Prasad
    Journal of Entomological Research, 2023
    AbstractDuring the period of investigation, aphids and pod borer complex were found to be the major pests causing economic losses during both the vegetative and reproductive stages, respectively. Temperature, evaporation and sunshine hours played an important role in the population fluctuation of aphids in lentil whereas temperature and wind speed had impact on the population fluctuation of aphids in field pea. Weather parameters such as wind speed and sunshine hours had a significant relation with the population of pod borer in both the crops. The population of natural enemies were found to be fluctuating within certain upper and lower limits throughout the cropping periods. The population of lady bird beetle showed positive and significant relation with the larval population of pod borer.
  • Seasonal incidence of insect pests associated with yam bean ecosystem in Dholi, Bihar
    Gouri Shankar Gin, Ashish Narayan, R.S. Singh, Neeraj Kumar, P.P. Singh, R. Prasad
    Journal of Entomological Research, 2022
    AbstractDuring the period of investigation, a number of insect fauna were found to be associated with the yam bean. Among them, pod borer (Maruca vitrata), Leaf hopper (Emposca spp.) and pod sucking bug (Clavigralla gibbosa) were dominant species. The incidence of pod borer and leaf hopper were started during the early growth period where as that of pod sucking bug was stated during the late growth period. It was observed that, temperature had a positive and significant relation with the population of leaf hopper and per cent flower infestation caused by pod borer whereas a negative and significant relation with the population of adult moth, pod sucking bug and per cent pod infestation. The population of adult moth had a positive and significant relation with morning RH whereas the population of leaf hopper had a negative and significant relation with the same. Per cent flower and pod infestation had a negative and significant relation with the evening RH. Rainfall was found to be influenced the activity of adult moth and pod sucking bug.
