A wide range of agricultural, horticultural and forest trees are vulnerable to insect borer pests causing serious loss to the economy. Cryptic nature of the borers causes the infestations to be overlooked until sizeable damage has occurred. Employing chemical or biological control has not yielded desirable results in suppressing these, as interventions hardly reach the target site/insect. However, the hazard of pesticides remains. Understanding the ecological interaction mediated by cues, especially odours between borers and their host will aid in the development of clean and green technologies.Full Text

The South American tomato moth Tuta absoluta (Meyrick) is a devastating pest of tomato. In the present study Tuta-adapted strains of Trichogramma were evaluated. Amongst the three species, Trichogramma achaeae Nagaraja and Nagarkatti, Trichogramma pretiosum Riley and Trichogrammatoidea bactrae Nagaraja could parasitise T. absoluta eggs and the parasitism rates were 5.0%, 51.1% and 68.2% respectively. Adults emerged from the parasitized T. absoluta eggs (4.8%, 97.5% and 90.0% adult emergence respectively). The F1 generation adults of T. pretiosum could parasitise 29% of Corcyra cephalonica Stainton eggs, while the other two species were not successful in parasitizing. In addition, four 'hymenopteran' parasitoids, viz. T. achaeae, Neochrysocharis formosa (Westwood), Habrobracon sp. and Goniozus sp. were also observed to be associated with T. absoluta in the fields during the surveys undertaken in southern India.Keywords

'Baits' are substances that attract, trap and kill pests. In horticultural practice, baits are used to trap insect pests, thereby diverting them from cultivated crops. An important insect pest that can be managed using baits is the fruit-piercing moth (FPM), Eudocima species. These frugivorous moths are distributed throughout India and inflict serious damage to a wide range of cultivated fruits. In southern India, pomegranate cultivation is escalating and so is the fruit damage caused by FPM. The damage by FPM alone sums up to 40% of the production, thus causing heavy loss to farmers. However, existing control measures are ineffective in reducing damage caused by the moths. In the present communication, we study the feeding preference of FPM to banana, guava, tomato and molasses in multiple and limited-choice field experiments. The results indicate that the moths are attracted to bait fruits, viz. banana, guava compared to the main crop, pomegranate. We conclude that using these aromatic fruits as baits, we can divert the moths from the main crop, which will serve as an economically viable control measure.Keywords

Human-wildlife conflict (HWC) is on the rise globally, and is one of the significant environmental problems in India. In India, HWC manifests itself in several ways, such as wildlife poaching, retaliatory killing of/injury to wildlife species, crop raiding and livestock predation by wildlife species, injury to humans or human mortality, and destruction of property, houses and buildings by wildlife. Of these, wildlife conflict in agro pastoral contexts has been a subject of debate and great concern nationally, not only for its impact on the farmers, but also for the consequences regarding wildlife conflict. In India, HWC involves multiple stakeholders and multitudinous socio-cultural and environmental issues. Hence any study on this topic must encompass a multi-disciplinary effort that provides a holistic understanding of the history of wildlife, crop and livestock raiding, its nature and consequences and discuss various techniques that have been used or recommended to mitigate the effects of this crisis.Full Text

When an animal or a plant species, unknown in a country, gets introduced, it is termed an exotic species often characterized by its prolific breeding, in the absence of any biotic natural enemies. Frequently, such introduced species end up as a pest/weed. These then become invasive alien species (IAS), threatening the economy.Full Text

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.

Reduviid predators are the largest terrestrial bugs considered to be potential biocontrol agents and an integral part of integrated pest management (IPM). Despite the rich fauna of reduviids and their prey records, potential studies on reduviid are relatively meagre. Understanding the biotic and abiotic factors influencing the reduviid population is essential to exploit them as biocontol agents in agriculture. Hence the present study was aimed at determining the abundance of reduviid, Isyndus heros in an organic mango orchard and to determine the impact of abiotic factors on its occurrence. The peak population of reduviids was found during the initial flowering phase (January) and vegetative phase (September–December). Correlation matrix showed that there was a significant positive correlation of between the population of I. heros and relative humidity, and significant negative correlation between maximum and minimum temperatures. Further, the significant variables were regressed and the highest coefficient of determination was found in maximum temperature (R2 = 0.62) with a single weather factor. However, multiple regression analysis revealed that the maximum and minimum temperatures could explain the variability up to 49%. This forms a baseline for the conservation and augmentation of reduviids that can be utilized as potential biocontrol agents in IPM programmes.Keywords
