As tawny crazy ants (Nylanderia fulva) invade the southern United States, they often displace
imported fire ants (Solenopsis invicta). After exposure to S. invicta venom, N. fulva applies
abdominal exocrine gland secretions to its cuticle. Bioassays reveal that detoxify S. these invicta
venom. Further, formic acid from N. fulva venom is the detoxifying agent. N. fulva exhibits this
detoxification behavior after conflict with a variety of ant species; however, it expresses it most
intensely after interactions with S. invicta. This behavior may have evolved in their shared South
American native range. The capacity to detoxify a major competitors venom probably
contributes substantially to its ability to displace s. invicta populations, making this behavior a
causative agent in the ecological transformation of regional arthropod assemblages.
Solution
Explanation:-
1. The scientific name of tawny crazy ants is Nylanderia fulva (N.fulva).
2. The N. fulva invade the Southern united states, and they have displaced Solenopsis invicta
(Fire ants).
3. When the S. invicta venom comes in contact with N. fulva, it secretes certain secretions form
the abdominal(relating to stomach) exocrine gland to its S.invicta cuticle(outer covering).
Bioassay (measurement of the concentration) reveals that the secretion from N.fulva detoxify
(removes toxin) from the S.invicta.
4. Usually, the formic acid is present in the secretion which acts as detoxifying agent.
5. N.fulva exhibits this detoxification behaviour with other ants as well but the intensity is most
with S. invicta. This may be due to their same habitat i.e. American native range.
6. The capacity of N.fulva to detoxify S.invicta shows its ability to displace S.invicta population..
