Histology Basics and Cell Death Detection in Honeybee Tissue
Published on: July 7, 2022
Summary
The social bee Trigona hypogea uniquely consumes carrion for protein, lacking stored pollen. Glandular secretions provide essential nutrients, showcasing an evolutionary adaptation to necrophagy in this bee species.
Area of Science:
- Entomology
- Evolutionary Biology
- Animal Behavior
Background:
- Social bees typically rely on pollen for protein.
- Trigona hypogea, a social bee, exhibits unusual dietary habits.
- Understanding dietary adaptations in social insects is crucial for evolutionary studies.
Purpose of the Study:
- To investigate the protein source of the social bee Trigona hypogea.
- To determine if Trigona hypogea utilizes carrion as a protein substitute for pollen.
- To explore the evolutionary implications of necrophagy in Trigona hypogea.
Main Methods:
- Observation of foraging behavior and nest provisioning.
- Analysis of larval provisions for pollen content.
- Assessment of glandular secretions for protein content.
Main Results:
- Trigona hypogea nests and larval provisions lack pollen.
- Worker bees show reduced corbiculae, structures for pollen transport.
- Glandular secretions contain approximately 20 percent protein, suggesting a pollen substitute.
Conclusions:
- Trigona hypogea has evolved necrophagy, using carrion as its primary protein source.
- Specialized adaptations, including toothed mandibles and recruitment behaviors, support this unique feeding strategy.
- This represents a significant divergence from typical bee nutritional strategies.

01:03Altruism
Altruistic behaviors are “unselfish” behaviors—those that help another individual at the expense of the individual carrying out the behavior. Despite the negative consequences for the altruistic animal, these behaviors are thought to have evolved for several reasons.
01:26Microbial Interactions: Cooperation
Microbial cooperation involves beneficial interactions in which different species work together for individual or mutual advantage. These interactions can profoundly influence ecological dynamics and evolutionary processes, and they are essential to many pathogenic and symbiotic relationships.Nematode–Bacteria CooperationA striking example is the relationship between the Gram-negative bacterium Xenorhabdus nematophila and the parasitic nematode Steinernema carpocapsae. Juvenile nematodes...
01:28Microbial Interactions: Predation
Microbial predation refers to the process by which one microorganism kills and consumes another to obtain nutrients and energy. It encompasses both bacterial and protozoan predators. This interaction plays a crucial role in shaping microbial communities and regulating nutrient cycling.Bacterial Predators: Epibiotic vs. EndobioticBacterial predators are classified based on their mode of attack as either epibiotic or endobiotic. Epibiotic predators, such as Vampirococcus, attach to the surface of...
01:16Necrosis
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...

00:41Phagocytosis
Cells pull particles inward and engulf them in spherical vesicles in an energy-requiring process called endocytosis. Phagocytosis (“cellular eating”) is one of three major types of endocytosis. Cells use phagocytosis to take in large objects—such as other cells (or their debris), bacteria, and even viruses.The objective of phagocytosis is often destruction. Cells use phagocytosis to eliminate unwelcome visitors, like pathogens (e.g., viruses and bacteria). It is perhaps unsurprising, that many...
