How does temperature effects the life cycle of Fruit fly?..
Effect of temperature on life cycle of fruit fly

Can we indentify that is there any effect of temperature on the life cycle of fruit flies?..
Since Cubists are working from different places accross the country…

Cubists from Kerala,Mumbai and Kochi can study life cycle in their respective place.
Red box is actually made in order to look for temperature difference…

Red box shows range of temperature in Thrissur kerala
Whereas Voilet box shows range of temperature in Bokaro Jharkhand…

Very simple method has been made Today in order to study life cycle of fruit flies at different places across the country.

Single gravid female will be trapped and will be transferred in Bottle A that will allowed to lay eggs and after egg laying the same mother fly will be transferred in bottle B and again after egg laying flies will be transferred to bottle C

If this experiment is executing in Thrissur kerala so according to that next generation will be seen on 9/01/2021 in bottle A, 10/01/2021 in bottle B
11/01/2021 in bottle C
This is how we can determine the Date of birth of flies in different bottles.

@⁨Rechel Turkey Cube Ranchi Moina⁩ @⁨Lydia cUBe Drosphila⁩ please add your inputs…

Butterfly-plant interaction
How do Butterflies indentify their host plant?

How do they sense or smell?..
Chmeo-receptors are present on the last segment of legs of Butterfly @krishna please quote the reference for the same…

Chemo-receptors of what?..
Chemicals that we can taste like salt and sugar or chemicals that we can smell like Acetic acid(vinegar).

    Drosophila is a genetically tractable system ideal for investigating the mechanisms of aging and developing interventions for promoting healthy aging. Here we describe methods commonly used in Drosophila aging research.

2 . Maximum life span (or, for humans, maximum reported age at death) is a measure of the maximum amount of time one or more members of a population have been observed to survive between birth and death. https://en.wikipedia.org/wiki/Maximum_life_span

3. Maximum life span contrasts with mean life span (average life span, life expectancy), and longevity. Mean life span varies with susceptibility to disease, accident, suicide and homicide, whereas maximum life span is determined by “rate of aging”.

4. Insects possess gustatory hairs or contact chemosensilla derived from mechanosensory bristles, scattered along a variety of appendages [2]–[4]. In adult butterflies and moths, gustatory sensilla are found on the labial palps and proboscis (Figure 1), the legs (Figure 2A) [5], the antennae (Figure 2B) [6], [7], and the ovipositor [8], [9]. In adult Heliconius charithonia legs, the 5 tarsomeres of the male foreleg foretarsus are fused and lack chemosensory sensilla, while female foretarsi bear groups of trichoid sensilla (n = 70–90 sensilla/tarsus) associated with pairs of cuticular spines [10]. Each trichoid sensilla contains five receptor neurons. These sensilla are sensitive to compounds that may be broadly classified as phagostimulants (e.g., sugars and amino acids), which promote feeding behavior, or phagodeterrents (secondary plant compounds), which suppress it [11]; in adult females they may also modulate oviposition https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3732137/
