Temporal and spatial gene expression analyses have a crucial role in functional genomics. Whole-mount hybridization in situ is useful for determining the localization of transcripts within tissues and subcellular compartments. Here we outline a hybridization in situ protocol with modifications for specific target tissues in mosquitoes.

How niches and stem cells form during development is an important question with practical implications. In the Drosophila ovary, germ line stem cells and their somatic niches form during larval development. This video demonstrates how to dissect, stain and mount female gonads from late third instar (LL3) Drosophila larvae.

This protocol describes the primary culture/co-culture of mouse ovarian tissue, using ovaries from neonatal mice and individual ovarian follicles from prepubertal mice. The culture techniques support development in a highly physiological manner, allowing investigation of the effect of extrinsic agents on the ovary, and of interactions between ovarian follicles.
FAQs
Juvenile hormone and ecdysteroids act as regulatory signals after a blood meal. They influence vitellogenin synthesis, secretion, and uptake by developing oocytes, linking endocrine regulation to yolk accumulation. This makes each stage of maturation chemically connected: signals control production of a yolk precursor, its release, and delivery into the cells that will form eggs.
Amino acids, lipids, and carbohydrates play complementary chemical roles in maturation. They supply materials for yolk formation and cellular growth rather than serving as interchangeable inputs. Following how these nutrient classes support developing oocytes helps connect metabolism with reproductive output and clarifies why ovarian maturation depends on both hormonal regulation and the availability of biochemical building materials.
The blood meal provides the physiological context for the hormonal and nutrient changes associated with maturation. After feeding, juvenile hormone and ecdysteroids regulate the sequence connecting vitellogenin production, secretion, and uptake. Examining this sequence helps distinguish failures in signaling from failures in supplying or incorporating the materials needed for yolk and cellular growth.
A biochemical study can examine three linked events: vitellogenin synthesis, its secretion, and its uptake by developing oocytes. It can also relate those events to the availability or use of amino acids, lipids, and carbohydrates. Keeping these stages distinct allows researchers to ask whether a change affects production, release, cellular incorporation, or general growth.
Potential control strategies can focus on molecular targets within the pathways that support egg maturation. Disrupting hormonal regulation, vitellogenin handling, or the use of nutrient materials could reduce successful maturation and mosquito fertility. This relevance makes ovarian biochemistry useful for exploring approaches that may lower populations of mosquitoes capable of sustaining disease transmission.
The immediate outcome of these pathways is successful or impaired egg maturation, while the broader consequence is a change in mosquito fertility. At the population level, altered reproductive success can influence mosquito numbers. In chemistry-focused research, these outcomes provide a biological context for evaluating how hormone signaling, vitellogenin handling, and nutrient use affect vector-control goals.
