Twinning program between Foldscope teams of The D. G. Ruparel College, Mumbai and Bijni College, Assam.

On third day we dissected four more freshwater fishes namely Epidocephalicthys gunthea, Psilorhyncus balitora, Acanthocobitis botia and Borioa darieo. We learned the taxonomic method of identification through foldscope. We prepared slides of different parts of body of fishes which included Mouth parts, Fins, Gills, and Scales. We observed all the slides through foldscope. We also prepared…

Different parts of Apis dorsata under foldscope

Apis dorsata is a giant honey bee. Tribals use this species for honey and beewax collection. Apis dorsata is also the natural host of the Tropilaelaps mite, a devastating parasite with an expanding distribution.


The eye arrangement can be a key factor when identifying spiders to family, and sometimes to genus, but are almost never useful in identifying to species. For identifying to species, spinnerets and leg details (especially first and 4th legs) are also useful. However, the best thing anyone can do is to get an extreme closeup…

Bryophyta Leaves

Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta. The name is derived from Latin word “funis” meaning a rope. Leaves are arranged on the axis in spiral fashion. The leaves are sessile, simple, green and distinct mid rib. The leaf is single layered thick except…

Ants Observed Under Foldscope

Ants Observed Under Foldscope.Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 140 million years ago, and diversified after the rise of flowering plants.

Trichogramma japonicum under the Foldscope

Trichogramma japonicum is the best biological control agent for the rice stem borer, which causes enormous yield losses year after year in India and several rice-growing countries in Asia. This minute parasitoid impedes the life cycle of the stem borer by attacking the latter’s eggs in the field. [Insects supplied by Dr Y. Lalitha]

Posterior Spircale of Stomoxys species

Stomoxys commonly known as stable fly resembles the house fly (Musca domestica).  Stable flies are obligate blood feeders and primarily attack cattle and horses for a blood meal (, 2018) The Stomoxys larvae was collected from an infected wound and was processed. The steps involved are: The larvae was boiled in 10% NaOH for about 5…

Documentation on the Collection of Cattle ticks

In response to Dr.Manu Prakash’s comment on our previous post, we are presenting the process of tick collection and the surroundings from which the ticks were collected. The ticks were collected from the cow  which had come to Large Animal Clinic (LAC) , Madras Veterinary College  on 27th September 2018 with the following symptoms:  fever,…

Parasitic infections in Cattle (a. Cattle ticks)

Endoparasites live inside the host. The may either be microparasites such as: blood protozoans (Theileria, Babesia, Trypanosomes) or macroparasites like: Helminths (Trematodes, Cestodes, Nematodes) Ectoparasites include ticks, mites, leeches, flies etc . They live on the outer surface of the host. The most common ectoparasites are ticks which causes cattle tick fever, Theileriosis ,Babesiosis etc….

Pollen Grains Observed Under Foldscope

Pollen Grains Observed Under Foldscope. Pollen is a fine to coarse powdery substance comprising pollen grains which are male microgametophytes of seed plants, which produce male gametes (sperm cells).

Observed the head and tail part of zebrafish

In the tail region we can see the vertebral arrangement along with the caudal fin. Eyes are the first thing to be observerd, they are mezmerizing. The fries were of 72 hrs when observed.

Yeast Cells

Yeast is a living organism. It can be used to make bread and alcoholic drinks such as beer and wine. Different species of yeast may cause infections such as thrush. Yeast consists of single cells. They are smaller than animal and plant cells, but slightly larger than bacteria.

Xylem and Phloem of a Monocot Plant

Dicot stems have their vascular bundles in a ring arrangement. Monocot stems have most of their vascular bundles near the outside edge of the stem. … Monocot roots, interestingly, have their vascular bundles arranged in a ring. Dicot roots have their xylem in the center of the root and phloem outside the xylem.

Antennae of male mosquito

Mosquitoes use their antennae as movement receivers that respond to oscillations of air particles within the insects’ surroundings. The brush-like male antennae are sensitive to sound waves, particularly to those of the frequency of the wingbeat of females; so when a male midge ‘hears’ a female with his antennae, he flies towards the source of…

Hair follicle

The base of the hair follicle is called the bulb. The hair bulb contains the actual hair producing part (tissue) known as the Dermal Papilla. The Dermal Papillae connects with the blood vessels to draw the nutrients for hair growth.

Elodea plant cell

This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. It is transparent, but…
