1. The storage of food is an
obvious strategy against
future shortages
2. Food storages occurs
sporadically among animals
3. Among social insects, long-
term, internal storage of
liquid foods has evolved
among ants, giving rise in
the extreme case to
honeypot ants such as the
desert-dwelling species of
the genus Myrmecocystus
in which a replete caste
stores liquid food in the crop
for months.
To see how the fire ants in the
food store that will be used for the future
To ask whether the ants similarly
stockpile dried insect prey pieces in their
natural nest.
Cultivation of beetle larvae
(Zophobus atratus)
Dyed in a solution of 0.5%
Rhodamin B is mixed with the
water
Fire ant colonies in the field and
in the laboratory
Beetle larva was
cut with half
elongated
Given in wet
condition
Given 10 gr of dye
Zophobus atratus on
fire ant colonies in the
field
Petri dishes were
closed on both
sides
Measured the reduction in
weight of larvae that had
been collected by fire ants
After 24 hors
Excavated nest of fire
ants to seen the storage
of food by using
ultraviolet light
For one day of feeding,
the chloroform was
sprinkled on the top of a
fire ant nest
Photographic trays used
as a fire ant colony nest
in the laboratory
fed with sugar water and beetle larvae
maintained in damp
conditions at a temperature
of 280 C
The researcher was observed evolution from the
behavior of fire ants maybe associated with the different
manner in which ants collect and transport liquid and
solid food
Liquids are taken into the distensible crop and shared by
trophallaxis, whereas solids are transported in the
mandibles.
The larva covers the pellet with salivary secretion,
which partly converts it into a liquefied product, which
is then collected and distributed around the colony by
worker trophallaxis
This tendency to separate the liquid food stream from
the solid may underlie the evolution of the preparation
of jerky.
The storage of food is an obvious strategy againstfuture shortages.
The result of insect prey obtained will be broughtto their nest and transformed into small pieces(Insect jerky)
The form of the result prey that is solid food andliquid food.
The worker ants transported the solid food in themandible whereas the liquid food are taken intothe distensible crop and shared by trophallaxis
