“…Investigating the impact of single and combined climate related drivers onto EPN survival and efficacy revealed no interaction between elevated temperature, CO 2, and decreased precipitation. While temperature is known to be a major driver of EPN survival and infectivity (Pervez et al 2015;Lalramliana & Yadav 2016;Aatif et al 2020), we did not find any impact of warming in our study. This discrepancy may be explained by the low range of temperature used in our study (19.6 -23°C) compared to the described beneficial temperature range (25 -30 °C) (Pervez et al 2015).…”

Climate change will profoundly alter the physiology and ecology of plants, insect herbivores and their natural enemies, resulting in strong effects on multitrophic interactions. Yet, manipulative studies that investigate the direct combined impacts of changes in CO2, temperature, and precipitation on this group of organisms remain rare. Here, we assessed how three day exposure to elevated CO2, increased temperature, and decreased precipitation affect the performance and predation success on species from four major groups of natural enemies of insect herbivores: an entomopathogenic nematode, a wolf spider, a ladybug and a parasitoid wasp. Future climatic conditions (RCP 8.5), entailing a 28% decrease in precipitation, a 3.4°C raise in temperature and a 400 ppm increase in CO2 levels, slightly reduced the survival of entomopathogenic nematodes, but had no effect on the survival of other species. Predation success was not negatively affected in any of the tested species, but was even increased for wolf spiders and entomopathogenic nematodes. Factorial manipulation of climate variables revealed a positive effect of reduced soil moisture on nematode infectivity, but not of increased temperature or elevated CO2. These results suggest that natural enemies of herbivores are well adapted to short term changes in climatic conditions and may not suffer from direct negative effects of future climates. These findings provide mechanistic insights that will inform future efforts to disentangle the complex interplay of biotic and abiotic factors that drive climate-dependent changes in multitrophic interaction networks.

“…(IISR-EPN 08) and O. gingeri against C. punctiferalis larva, by dose response and time exposure assay and determination of median lethal dose (LD 50 ) and lethal time (LT 50 ) indicated that Steinernema sp. (IISR-EPN 02) and O. gingeri were more promising (Pervez et al 2014c). These four promising isolates were evaluated against C. punctiferalis infesting ginger and turmeric under field conditions at Peruvannamuzhi.…”

Pest control strategies based on relatively non-toxic procedures that preserve the health of the ecosystem and minimizes negative effects on beneficial organisms, and utilize microbial pathogens and their products, plant natural products, semiochemicals, biotechnological strategies and reduced-risk pesticides can be termed as ‘biorational strategies’. This review consolidates the information available on the use of biorational strategies for the management of insect pests of spice crops such as Piper nigrum (black pepper), Elettaria cardamomum (cardamom), Zingiber officinale (ginger), Curcuma longa (turmeric), Coriandrum sativum (coriander), Cuminum cyminum (cumin) and Foeniculum vulgare (fennel). The review also identifies the current gaps in knowledge and the opportunities and challenges in using biorational strategies for the production of clean spices, reflecting the global concern over pesticide misuse.
