This laboratory study evaluate the morphometrics of fall army worm Spodoptera frugiperda (J E Smith) influenced by four cereal host plants. In maize, larval head capsule width was 0.22, 0.42, 0.71, 1.13, 1.29 and 2.94 mm for I to VI instars, respectively in sorghum was 0.20, 0.41, 0.67, 1.06, 1.24 and 3.05 mm for I to VI instars, respectively. In pearl millet, larval head capsule width was 0.19, 0.29, 0.52, 0.83, 1.23 and 2.80 mm, for I to VI instars, respectively. In sugarcane, head capsule width was 0.22, 0.43, 0.67, 0.94, 1.22 and 2.70 mm for I to VI instars, respectively. The mean pupal length varied significantly when reared on different cereal host plants, it was significantly maximum on maize (15.10 mm) followed by sorghum (14.20 mm), sugarcane (13.10) and lowest on pearl millet (12.30 mm). The significantly maximum pupal weight was noticed on maize (185.90 mg) followed by sorghum (144.40 mg), sugarcane (124.80 mg) and lowest on pearl millet (104.70 mg).

The foraging activity of Apis cerana indica F with specific to their floral handling time on sunflower has been investigated at MSSSoA, Centurion University of Technology and Management in Gajapati district of Odisha in two cropping seasons. Floral handling time was to be maximum during mid flowering stages and the least during late flowering. The mean time spent on flowers was higher during 10:00-11:00 AM in the second season whereas it was during 01:00-02:00 PM in the first season.

The production and productivity of rice is constrained by various insect pests but very meagre information is available on the seasonal incidence of the Crambidae pests of rice in the subtropical region of Madhya Pradesh. The present study was undertaken on the seasonal incidence of Crambidae pests at the Regional Agricultural Research Station, College of Agriculture, Balaghat, Madhya Pradesh during January -May, 2022. Rice variety JRB-1 was sown in a 300 m2 plot, damage of pests were recorded and correlated with the weather data. Stem borer damage manifested in the form of deadhearts and white ears, started from second fortnight of February and gradually increased till late April. Leaf folder incidence was observed from early March to early April. Incidence of these were found to be correlated positively with temperature and wind velocity whereas, negatively with relative humidity and rainfall. The pattern of incidence of these pests of rice in the subtropical region of central India (Balaghat, MP) were more or less similar to those of the tropics.

Field experiments were conducted in Fayoum Governorate to evaluate the impact of weeds growing in cucumber fields on the incidence of sucking pests viz., Aphis gossypii (Glover), Bemisia tabaci (Gennadius), Nezara viridula (L.), Phenacoccus solenopsis (Tinsley), Thrips tabaci (Lindeman), Myzus persicae (Sulzer), Empoasca decedens (Paoli) and Empoasca decipiens (Paoli) during 2018 and 2019 Neglected cucumber fields, with a high density of weeds, were observed to harbour more pests 57.7 and 55.9%, respectively. Meanwhile, the cucumber free-weedy field hosted the lowest rate of occurrence for all insect pests represented by 42.3 and 44.1%, respectively. Neglected fields with abundant weeds provide a favourable habitat, leading to increased incidence. Understanding the relationship between weeds and pests is crucial for developing effective IPM strategies in cucumber.

The rice leaf folder Cnaphalocrocis medinalis Guenee has become a major concern, causing outbreaks in various parts of India. A lifetable study was conducted to analyze the growth, survival, reproduction, and mortality of C. medinalis, aiming to determine the weakest lifestages and unravel its population dynamics. The study observed the highest survival rate at the fourth-instar larval stage and the lowest during the egg and first-instar larval stages. A population trend index of 5.9 was observed, indicating significant population growth.

Social insects are arthropods that lives in a community with other members of the same species. Eusocial insects frequently lose colony members as a result of living in big groupings. They perform cooperative corpse management to maintain the hygiene of the nest, exhibiting behavioural and physiological responses that promote disease resistance, nutrient reallocating and colony protection. Undertaking behaviour is most common in social insects belonging to Hymenoptera and Isoptera which adopts various mechanisms of death recognition, convergent and divergent behavioural responses towards dead items. Corpse removal, burial, cannibalism and avoidance are different solutions evolved by social insects, independently towards the problem of corpse management. Genetic studies and gene expression analysis related to social immune systems gives a better knowledge on behavioural and physiological disease defense in insects which could be considered a novel access to biological pest control. This article provides a comprehensive understanding of corpse management in social insects.

In this study, intensive screening for mosquitocidal bacteria from different agricultural soils of Vellore district of Tamil Nadu was carried out to isolate potential mosquitocidal bacteria. From a total of 315 soil samples, 945 bacterial isolates were cultured, out of which three isolates showed mosquitocidal activity. One most potential mosquitocidal isolate was selected out of these and studied further. The isolate was identified by ilvD primer and phylogenetic tree as Bacillus thuringiensis israelensis. This new isolate exhibited effective toxicity against Aed. aegypti, An. stephensi, and Cx. quinquefasciatus. The LC50 values were 0.757, 0.52 and 0.165 mg/ l respectively. Similarly, the LC90 values were 0.963, 0.794 and 0.355 mg/l, respectively. These results depict that the new isolate (Bti) VEVP-60 is a good candidate for mosquito control.
