Opis:
Ant-aphid mutualism is considered as a beneficial, reciprocal and myrmecophilous association. Ants farm aphids, harvesting honeydew or flesh, in return protect the aphids from their natural foe i.e. predators and parasites and perhaps for other benefits like acceleration of aphid’s growth and reproductive rate and in the establishment of aphid colony. And finally aphid could get a pest status. Some of the aphid species are better adapted to profit from the presence of ants than others and benefits are more marked in small populations than in large ones (Saha & Raychaudhuri, 1998). Therefore, it seems essential to know about the interacting ants, their relationship with aphids in any agroecosystem for a better management strategy. The present paper attempts to document the aphids and aphidocolous ants against different host plants. Our investigation during August, 2017 – July, 2018 results a total of 40 aphid infested host plants along with 7 species of aphidocolous ants. Out of 10 aphid species recorded Aphis gossypii (Glover) is tended by more no. of ant species (5) followed by Rhopalosiphum maidis (Fitch) by four (4) species of ants. Aphidocolous ants demand serious attention as their attendance promotes aphids to reach pest status as well as ant populations need a check so that they may take care of fewer aphid individuals.

Opis:
Our study on ant diversity of Bibhutibhusan Wildlife Sanctuary, N-24 Parganas, West Bengal during the period, August 2017-July 2018, unfolded wonderful Batesian and Wasmannian mimicry (chemical mimicry) between model ants Tetraponera rufonigra (Jerdon) and its sibling T. allaborans (Walker), Oceophylla smaragdina (Fabricius) and salticid spiders of the genus Myrmarachne Macleay. Siblings of Myrmarachne encountered are M. plataleoides O. P. Cambridge, M. maratha Tikader and M. orientales Tikader. It is supposed that chemical or Wasmannian mimicry enables species with ant-like pheromones to live in close contact with ants. The members of spider Myrmarachne that resemble the aggresive weaver ant Oceophylla smaragdina, with which they live in close contact, also show chemical resemblance. Further, by mimicking the ants they gain protection from predators. Since weaver ants have a painful bite and also taste bad, this strategy appears to be successful. Though these spiders mimic the weaver ants very well, they are known to stay away from them. They weave a thin web on the leaves, hide under their webbing and ambush their prey. Present communication attempts to discuss the morphological and structural similarities between the mimics and their models. It is worthwhile to mention that such a mimicry is reported for the first time from this part of the country.

Opis:
Presented work is aimed at investigating potential correlations between remote sensing vegetation indices and local ant populations. Research was conducted in summer of 2017 in Wigry National Park in two types of forest habitats: coniferous (Serratulo-Pinetum) and deciduous (Tilio-Carpinetum). NDVI and MCARI2 vegetation indices were measured with the use of a drone and yielded comparable correlations with ant-related quantities. We determined that the presence of ants from Formica group is positively correlated with vegetation indices, while the correlation between Myrmica and Lasius ants and vegetation indices is more complex.

Opis:
Autonomic computing promises computer systems capable of self-management, which augurs great promise for unmanned spacecraft. Such spacecraft are extremely appropriate for deep space exploration missions because the former bring onboard intelligence and less reliance on control links. The Autonomic System Specification Language (ASSL) is a framework for developing autonomic systems. As part of our research on ASSL, we have successfully specified autonomic properties, verified their consistency, and generated implementation for both the NASA ANTS (Autonomous Nano-Technology Swarm) concept mission and the NASA Voyager mission. This paper presents concrete results on the use of ASSL to develop a self-healing behavior model for NASA ANTS swarm-based exploration missions. Here, we present specification and implementation results. Moreover, we experiment with the ASSL-generated code to demonstrate that the implemented ANTS system is capable of self-management in respect of the specified self-healing model.
