“…In contrast, despite variations in barometric pressure, immature and adult D. luteipes exhibit similar foraging behaviour. Earwigs, which are hemimetabolous insects, typically do not undergo drastic variations in morphological and ecological characteristics throughout life (Cruz, 2009 ; Reis et al, 1988 ; Truman, 2019 ). In maize fields, earwigs at all stages utilize the same strategy to shelter and protect themselves from environmental stressors such as desiccation, high temperatures, rain and solar radiation (Cruz, 2007 ; Sauphanor & Sureau, 1993 ).…”

Abiotic factors strongly influence ecological interactions and the spatial distribution of organisms. Despite the essential role of barometric pressure, its influence on insect behaviour remains poorly understood, particularly in predators. The effect of barometric pressure variation can significantly impact biological control programs involving entomophagous insects, as they must efficiently allocate time and energy to search for prey in challenging environments. We investigated how predatory insects from different taxonomic groups (Coleoptera, Dermaptera and Neuroptera) adapt their foraging behaviour in response to variations in barometric pressure (low, medium and high). We also examined the response of different life stages to changes in pressure regimes during foraging activities. Our results showed that the searching time of Doru luteipes (Dermaptera: Forficulidae) was faster in a favourable high‐pressure regime, whereas Chrysoperla externa (Neuroptera: Chrysopidae) and Eriopis connexa (Coleoptera: Coccinellidae) had similar searching times under varying pressure regimes. Although no differences in prey feeding time were observed among the studied species, the consumption rate was influenced by low barometric pressure leading to a decrease in the number of preyed eggs. Moreover, we provide novel insights into how hemimetabolous (D. luteipes) and holometabolous (E. connexa) species at different life stages respond to barometric pressure. Doru luteipes nymphs and adults had similar consumption rates across all pressure regimes tested, whereas E. connexa larvae consumed fewer eggs under low barometric pressure, but adults were unaffected. This highlights the importance of investigating how abiotic factors affect insects foraging efficiency and predator–prey interactions. Such studies are especially relevant in the current context of climate change, as even subtle changes in abiotic factors can have strong effects on insect behaviour. Barometric pressure is a key meteorological variable that serve as a warning signal for insects to seek shelter and avoid exposure to weather events that could potentially increase their mortality. Understanding the effects of barometric pressure on predatory insects' behaviour can help us develop more effective pest management strategies and promote the resilience of agroecosystems. We provide new insights into the complex relationship between barometric pressure and predator–prey interactions.

There are also species that parasitise the larval stage of the pest, but only cause mortality of the insect host in its pupal stage, such as Archytas marmoratus (Townsend, 1915) (Diptera: Tachinidae) (Gross and Young, 1984).…”

In the context of the modern agriculture, pest control is important in order to increase productivity in maize (Zea mays L.). However, this control should be done rationally, prioritising environmentally safer methods such as biological control. This paper aims to report the occurrence of Dolichozele koebelei Viereck, 1911 (Hymenoptera: Braconidae) in Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) larvae collected in maize subjected to different cropping systems. The experiment was conducted at the Centro Nacional de Pesquisa de Milho e Sorgo (CNPMS) in Sete Lagoas, Minas Gerais State, Brazil, using organic and conventional production. Ten plants were sampled from each of the 24 plots and for each production system, three times a week during the entire cycle of maize (variety BR 106). In the laboratory, larvae were distributed in individual rearing containers with artificial diet until the end of the biological cycle. An increased number of S. frugiperda larvae was observed in organic single crop maize; hence a higher percentage of S. frugiperda larvae parasitised by Hymenoptera and Diptera also occurred in the maize under this production system. Dolichozele koebelei had not yet been described in association with larvae of S. frugiperda. The percentage of parasitism of S. frugiperda larvae was high in both experiments, indicating the importance of natural control agents in reducing the population density of S. frugiperda, and especially the importance of an appropriate crop management.Keywords: agroecosystem, biological control, fall armyworm, parasitoid, Macrocentrinae.

Fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a polyphagous pest which is arising as one of the major threats to agricultural crop production. It has around 80 host species that cause severe damage to cereals and vegetable crops. This pest was first discovered in Africa (2016) and first collected and reported in Madhya Pradesh at Research Farm RVSKVV, Gwalior of the August Month in2019-20. The S. frugiperda larval are found in newly leaves, leaves whorls, tasseling or cobs according to their growth stages. Scrape leaves, pin hole symptoms due to early larval stage and pane window symptoms whereas in the later vegetative stages due to larval of fall armyworm, damage results in skeletonized leaves and seriously windows whorls. Whereas weather condition for insects firm is good for pest could cause about 100% losses in maize crop but not control in the time. Normal investigation, push and pull method, light traps are used, common botanical pesticides are available of neem locally available materials of ash and several suggested chemical pesticides with dose can be used for the management of S. frugiperda. In present a vital requirement for development of eco-friendly environment, cost-effectively and collectively adopted IPM strategies to easily the impacts of the S. frugiperda.
