Background: Considering the disadvantages of chemical insecticides, we aimed to evaluate parasites for control of mosquito larvae of and at different larval stages.
Methods: sp infected mosquito larvae were crushed in the 0.85% saline and homogenized well to get in suspension. The effects of sp infections on larval development were investigated by inoculating protozoan on different larval instars of and and observed under light microscope. Lethal time of the infected larvae at different stages was calculated.
Results: First and 2 larval instars of both and did not show signs of infection by sp., whereas 3 instars of showed more infection than those of . However, 4 larval instars of both mosquitoes were heavily infected with parasite which was responsible for sluggish movements of larvae and eventually death. Moreover, parasites ( spp) were responsible for more than 90% reduction in adult emergence for both infected and .
Conclusion: This study provides insights for mosquito larvicidal action of surface parasite on different larval stages of and . It could be suggested as a potential candidate in mosquito biocontrol programs.

N-Nitrosodimethylamine (NDMA) is a known water disinfection byproduct (DBP) characterized as a potent hepatotoxin, promutagen, and probable human carcinogen; this is because of the metabolites associated with its biotransformation. The metabolism of NDMA produces formaldehyde, another alkylating agent and DBP. Both compounds are generated from natural and anthropogenic sources, but the safety restrictions applied to NDMA do not extend to the uses of formaldehyde.

Chironomidae have a wide distribution in Neotropical aquatic ecosystems and are predominant in the macroinvertebrate biota of these ecosystems, such as shallow lakes and swamps. In recent years, there has been a notable increase in research efforts aimed at understanding the biology of chironomid, and research on the bionomy of this group is still limited. Therefore, the objective of this study was to describe the growth and development of Chironomus calligraphus and Goeldichironomus holoprasinus, maintained under controlled laboratory conditions.

Parasitoids employ diverse oviposition strategies to enhance offspring survival and maximise fitness gains from hosts. Ladybird parasitoids, significant natural enemies of ladybirds, have the potential to disrupt biocontrol efforts, yet their biology and ecology remain poorly understood. This study investigated the host-parasitoid interaction among three sympatric larval endoparasitoids of (Coleoptera: Coccinellidae): (Hymenoptera: Encyrtidae), (Hymenoptera: Proctotrupidae) and (Hymenoptera: Eulophidae).

The bipartite GAL4/UAS system is the most widely used method for targeted gene expression in and facilitates rapid genetic experimentation. Defining precise gene expression patterns for tissues and/or cell types under GAL4 control will continue to evolve to suit experimental needs. However, the precise spatial and temporal expression patterns for some commonly used muscle tissue promoters are still unclear.

Long-horned beetles are among the major insect pests that can cause significant economic and ecological damage globally. The control of long-horned beetles is crucial to sustain the forest ecosystem. , an economically important ectoparasitoid of long-horned beetles, is widely utilized in biological control strategies.
