BACKGROUND Trypsin Modulating Oostatic Factor (TMOF) terminates trypsin biosynthesis in adult and larval mosquito gut. It will inhibit the growth and development of mosquito larvae feeding on it resulting in death by starvation. The objective of this study is to determine the effective dose of Pichia-TMOF and the combination of Pichia-TMOF with Bacillus thuringiensis (Bt) as larvicide on Ae. ae...

For organisms with complex life cycles, processes occurring at the interface between life stages can disproportionately impact survival and population dynamics. Temperature is an important factor influencing growth in poikilotherms, and growth-related processes are frequently correlated with survival. We examined the influence of water temperature on growth-related early life history traits (EL...

For many marine fish, intense larval mortality may provide considerable opportunity for selection, yet much less is known about the evolutionary potential of larval traits. We combined field demographic studies and manipulative experiments to estimate quantitative genetic parameters for both larval size and swimming performance for a natural population of a common coral-reef fish, the bicolor d...

We tested empirically whether microclimate and relative timing of oviposition affected prediapause larval survival and development rates in the federally threatened Bay checkerspot butterfly, Euphydryas editha bayensis (Nymphalidae). Most mortality in Bay checkerspot butterflies occurs among prediapause larvae. Because phenology of the butterfly’s larval hostplant, Plantago erecta, has been tho...

Crocidolomia pavonana is an important pest of broccoli plants. Pest control currently still using chemical pesticides that negatively impact the environment. It hoped Beauveria bassiana will become one environmentally friendly bioinsecticides. The research aimed to study virulence level conidia density B. as a bioinsecticide against C. pests on This experiment used completely randomized design ...

The extensive use of chemical insecticides to control mosquitoes led the development insecticide resistance and environmental health hazards. This caused a surge in interest eco-friendly biocontrol agents. present study aimed explore susceptibility different instar larvae common mosquito, Culex pipiens Linnaeus, 1758, mermithid nematode, Romanomermis iyengari Welch, 1964. Moreover, effects R. o...

The goals of this study were to explore and identify entomopathogenic fungi, as well determine the most effective application techniques control S. frugiperda from exploration infected Spodoptera larvae in Purbalingga Regency. research was carried out at Plant Protection Laboratory, Faculty Agriculture, Jenderal Soedirman University, January May 2022. Samples collected by purposive random metho...

Drosophila is a suitable model organism to test phytochemicals. The objective of our study was to explore the potential of Achyranthes aspera on reproductive fitness of Drosophila melanogaster using larval and adult feeding methods. The decrease in the fecundity, fertility, developmental time, ovarioles number, hatchability and viability was observed in adult feeding than larval feeding methods...
