Incidence of Aggressive Territoriality between Two Ant Species: Camponotus compressus Fab. and Oecophylla smaragdina Fab. (Hymenoptera:Formicidae)

Interspecific rivalry among higher animals is not uncommon. However, it is less noticed among invertebrates, which function at micro ecological levels. One such incident was encountered by the authors in an old, neglected mango orchard on the outskirts of Bengaluru, India, between two species of ants, Camponotus compressus Fabricius and Oecophylla smaragdina Fabricius. While these two spatially co-existed and foraged in the orchard, rivalry was found on three trees which harboured arboreal O. smaragdina nests, where C. compressus (a ground nester) also began nesting at the base of the tree.Foragers of O. smaragdina while descending the tree trunks found C. compressus at the base of the tree an intrusion (or vice versa?) and interspecific rivalry ensued for nearly seven weeks leading to mortality in both species. Overall, O. smaragdina suffered six times more loss in terms of number and biomass, but prevailed over C. compressus. The latter was forced to abandon nesting. It is important to record such interspecific processes, in insects at a micro ecological level.

“…1), whereas the predator was present throughout the period of observation, thus allowing the predator to perform without any interference by the ant. Verghese and Tandon (1987) reported on the total exclusion of the ant Camponotus compressus (Fab.) in the predation of the aphid A. gossypii by the coccinellid predator, C. sexmaculata.…”

“…This was also reflected in the overlapping index (γ) and as evidenced by spatial correlation coefficient values where the degree of association between pest and predator was high at all the strata of the plant (Table 7). The coefficients were positive and the values were within the range of 0 to 1 and not close to 0, indicating partial overlap between the pest and predator, with (Verghese and Tandon 1987).…”

The information on biological activity and species interaction in an ecosystem is essential to understand the mutualism and resource acquisition. A study was taken up to understand the interspecific association among whitefly, its predator and the associated ant species in Capsicum ecosystem. The whitefly was identified as invasive solanum whitefly, Aleurothrixus trachoides (Back), the coccinellid, which was predating on the whitefly as Axinoscymnus puttarudriahi Kapur and Munshi and the associated ant as Tapinoma melanocephalum (Fabricius). Studies on spatial distribution of the pest, predator and ant revealed that the pest and the predator followed aggregate distribution in upper and middle leaves of the plant. A highly significant positive correlation was exhibited between the predator grub and the immature stages of the whitefly as confirmed by Chi-square test, which was evident throughout the plant. Tapinoma melanocephalum exhibited positive association with the pest only in the lower leaves of Capsicum. The non-significant association of T. melanocephalum with the coccinellid predator, indicated that the ant did not interfere with the performance of the predator. The significant positive association of the coccinellid predator larvae and adults with the immature stages of the pest throughout the plant indicated the predatory efficiency of A. puttarudriahi, which needs to be conserved.

“…They revealed the reason to be due to the migration of the pests' species and predators from the guava trees to attack other fruit orchards or other crops (representing the period of fall of the guava leaves in the year). However, Verghese and Tandon (1987) stated that there was a positive association between the cotton aphid A. gossypii and the coccinellid predator Menochilus sexmaculatus in an unsprayed guava ecosystem. Therefore, it is very important to recognize both the positive and the negative interactions that occur between the two primary components of a management system, plant cultivars, and natural enemies when planning Integrated Pest Management (I.P.M.)…”

The journal of Toxicology and pest control is one of the series issued twice by the Egyptian Academic Journal of Biological Sciences, and is devoted to publication of original papers related to the interaction between insects and their environment. The goal of the journal is to advance the scientific understanding of mechanisms of toxicity. Emphasis will be placed on toxic effects observed at relevant exposures, which have direct impact on safety evaluation and risk assessment. The journal therefore welcomes papers on biology ranging from molecular and cell biology, biochemistry and physiology to ecology and environment, also systematics, microbiology, toxicology, hydrobiology, radiobiology and biotechnology. www.eajbs.eg.net Provided for non-commercial research and education use.Not for reproduction, distribution or commercial use. ABSTRACT Article HistoryBahy El-Din, I.A. and El-Khawas, M.A.M 98 other recorded predators. For this reason, a biological control experiment was performed by laboratory mass-rearing and releasing the predator H. convergens adults (pairs of males & females), for controlling the cotton aphid A. gossypii on the guava trees during season, 2019 (in a guava orchard near the orchard used in comparing the seven parameters). The percentages of reduction in the experimental area (in which the predator H. convergens were released) were; 17.19%, 53.98%, 73.85%, 76.26%, 72.65% and 55.16% in comparing with the control area (in which the predator H. convergens was not released at all) in case of the following features: the mean of infested trees/10 trees, the mean of infested leaves/500 leaves, the mean number of cotton aphid A. gossypii/one guava leaf, the total number individuals of winged aphid adults, the total number of wingless aphid individuals and the total number of the aphid species/season 2019, respectively. So, the predator H. convergens is a useful biocontrol agent for the cotton aphid A. gossypii and could be laboratory mass-reared and field released on a large scale against the pest on the guava trees or other fruit trees, side by side with other available safe control methods in the frame of Integrated Pest Management (I.P.M.) programs, for protecting man heath and the surrounding environment from pollution.
