“…, Reddy et al. ). Although our time series are generally not long enough to detect temporal changes in periodic behavior—such time series are rare in ecology—we gain insight into how global change can affect periodic insect outbreaks by separating cycles arising via density dependence from those driven or altered by environmental forcing.…”

Population dynamic responses to global change have varied widely among taxa. Most studies of population dynamics of insect pests focus on one or a few species, leaving open the question of whether changes in outbreak patterns are species‐specific or reveal predictable responses to global change, and what factors explain differences among populations. We analyzed 64 multi‐decadal time series of agricultural and forest pest insect populations in the United States. We first characterized populations according to long‐term trends, strength of population regulation, and cycle presence and length. We then asked whether these attributes could be predicted by geography, taxonomy, and life‐history traits. Roughly half of time series exhibited a long‐term trend, and agricultural pests were more likely to be declining, while forest pests were more likely to be increasing. Approximately one quarter of records exhibited periodic oscillations, and we used their statistical properties to infer whether the oscillations were environmentally forced or arose from density dependence. Insects hatching in early spring may be more strongly influenced by environmental forcing, for example, early springs or late spring frosts, than species hatching later. Our findings suggest roles of climate change, forest compositional change, and agricultural practices in driving long‐term change in pest populations.

“…High winter temperatures can affect and also influence the presence and outbreaks of insect pest (Reddy et al, 2015). Warmer winters can result to reduction in mortality rates of insect pests and this often leads to high infestations on crops thus increasing the damage and yield loss (Harrington et al, 2001).…”

“…The African bollworm (Herlicoverpa amigera) is regarded as one of the major insect pest in agricultural production. This insect has the ability to overwinter due to increased temperatures in winter season (Reddy et al, 2015). The southern green stink bug (Nezara viridula): heteroptra: pentatomidae) showed a high survival rate in winter season due to increased warmer conditions (Musolin et al, 2009).…”

Constraints to Vegetable Production Resulting from Pest and Diseases Induced by Climate Change and Globalization: A Review

Vegetable production worldwide is constrained by pests and diseases which effects are exacerbated by climate change and variability. Greenhouse gas emissions are also increasing due to poor agricultural practices and other human activities. This will continue to have a negative impact on the prevalence of insect pests and diseases. This review focuses on the climatic factors that impact on insect pests and diseases of vegetable crops. High atmospheric temperatures and elevated carbon dioxide increases pest development, survival of pests and distribution of pest to new areas. The distribution of insect pests and diseases are not due to climate changes only but are also a result of globalisation and poor biosecurity measures at country borders. There is limited information on the distribution of pests and diseases due to globalisation in African countries. New exotic pests will continue to be introduced to countries if biosecurity measures are not improved. Future research must focus on how to manage emerging pests and diseases influenced by high temperatures and carbon dioxide and other climatic conditions which influence pest severity under smallholder farmers in the southern African regions.

“…implies that when the environment varies among years or changes directionally, e.g. in terms of a warming climate, the phenology of different species can be influenced to different extents, leading to changes in the relative timing of interacting species (Both et al 2009, Singer and Parmesan 2010, Thomson 2010, Gienapp et al 2014, Reddy et al 2015, Kharouba et al 2018. The effects of environmentally induced changes in synchrony on interaction intensities and trait preferences are likely to be most pronounced for species interactions that depend strongly on synchrony, e.g.…”

Variation in the degree of synchrony among host plants and herbivores can disrupt or intensify species interactions, alter the strength of natural selection on traits associated with phenological timing, and drive novel host plant associations. We used field observations from three regions during four seasons to examine how timing of the butterfly herbivore Anthocharis cardamines relative to six host plant species (Arabis hirsuta, Cardamine pratensis, Arabis glabra, Arabidopsis thaliana, Thlaspi caerulescens and Capsella bursa‐pastoris) influenced host species use and the choice of host plant individuals within populations. Butterflies laid a larger fraction of their eggs on species that were closer to the butterfly's preferred stage of development than on other host species. Within host plant populations, butterflies showed a stronger preference for individuals with a late phenology when plants within the population were on average more developed at the time of butterfly flight. Our results suggest that changes in synchrony between herbivores and their host plants are associated with changes in both host species use and the choice of host plant individuals differing in phenology within populations. This is likely to be an important mechanism generating variation in interaction intensities and trait selection in the wild, and therefore also relevant for understanding how anthropogenic induced changes, such as global warming, will influence natural communities.
