“…On the other hand, changes in frost pattern, are one of the drivers of the spread of the frost-sensitive insect pests [ 91 ]. The frequency of spring frosts decreases with increasing temperature, so longer warm periods extend the period and intensity of insect epizootics [ 92 ]. Crop growers can in theory benefit from earlier seeding, but as a consequence these plants then become available to insect pests sooner, allowing them to begin feeding earlier and cause greater damage, as well as potentially producing additional insect generations during the typical growing season [ 92 ].…”

“…Parmesan and Yohe [ 19 ] found that insect species are spreading at an average rate of 6.1 km per decade due to climate change. This is happening due to the increase in temperature in these areas and is causing insects to survive where they could not previously thrive [ 92 ].…”

“…Potential adaptation strategies have been identified to reduce the risks of spreading new pests and diseases, and to mitigate the negative impacts of existing pests. The most commonly mentioned strategies are modified integrated pest management (IPM) practices, monitoring climate and insect pest populations and the use of modeling predictions tools [ 92 ] ( Figure 4 ).…”

Climate change and global warming are of great concern to agriculture worldwide and are among the most discussed issues in today’s society. Climate parameters such as increased temperatures, rising atmospheric CO2 levels, and changing precipitation patterns have significant impacts on agricultural production and on agricultural insect pests. Changes in climate can affect insect pests in several ways. They can result in an expansion of their geographic distribution, increased survival during overwintering, increased number of generations, altered synchrony between plants and pests, altered interspecific interaction, increased risk of invasion by migratory pests, increased incidence of insect-transmitted plant diseases, and reduced effectiveness of biological control, especially natural enemies. As a result, there is a serious risk of crop economic losses, as well as a challenge to human food security. As a major driver of pest population dynamics, climate change will require adaptive management strategies to deal with the changing status of pests. Several priorities can be identified for future research on the effects of climatic changes on agricultural insect pests. These include modified integrated pest management tactics, monitoring climate and pest populations, and the use of modelling prediction tools.

“…The number of generations per year may increase as the insects tend to grow faster in the warmer climate (Jaworski, Hilszczański, 2013). S. lineatus speeds up the development and extends the period and rate of reproduction, which in turn will increase insect abundance and crop damage (Reddy, 2013;Raza et al, 2015). The As shown in Table 2, adult density in untreated plots at the faba bean growth stage BBCH 12 was quite high (7.5 beetles per m 2 ).…”

This research was carried out at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry during the growing seasons of 1985-1988 and 2017-2018. The aim of this study was to analyse the changes in pea leaf weevil (Sitona lineatus L.) abundance in faba bean as affected by the air temperature and rainfall over the past more than 30 years. To collect adults of S. lineatus, yellow water traps were used during the growing season in both study periods. Larvae were counted in root nodules and in the surrounding soil. To determine the foliar damage, automatic leaf area scanner was used in 1985-1988, while in the second experimental period foliar damage was estimated by counting the number of U-shaped notches on leaves. The results showed that the trend of temperature maximums and minimums increased during three decades, and the amount of rainfall was uneven through the years. The increase in average air temperature was rapid in the recent three decades, which resulted in the change in the day-degrees required for S. lineatus. In the present study, the recorded accumulative thermal units over the two periods from 1985 to 1988 and from 2017 to 2018 showed a rise in day-degrees. The pyrethroid treatment was significantly effective against foliar damage, but it was ineffective in reducing the number of larvae and damaged nodules compared to the untreated. Further research on the bioecology of S. lineatus and on the effective timing of its control is needed in Lithuania. The results obtained in this study supplement the already existing agricultural practices aimed at improvement of pea leaf weevil management in faba bean.
