“…Similarly, Bajia and Singh (2014) found that the coccinellid population was greatly influenced by different weather parameters and reported that the maximum and minimum temperature showed a positive correlation with the coccinellids population, whereas relative humidity had a negative correlation. The present findings are in partial accordance with the findings of Kataria and Kumar (2016) who reported that the ant population on cowpea showed a negative correlation with maximum and minimum temperature.…”

“…The pest population was very low at the time of crop harvesting during 8 th SMW and these were 9.38 and 4.26 per 30 cm apical shoot per plant in variety KPMR 935 and IFPD 122, respectively. The results are in partial agreement with Kataria and Kumar (2016), who found that maximum infestation of A. craccivora occurred in February to March on cowpea in Gujarat. The results are also more or less in agreement with Srikanth and Lakkundi (2014), who stated that the population of A. craccivora on cowpea increased rapidly with crop growth and their peak coincided with peak pod formation which may be due to higher availability of quality proteins in the plant and is very essential for aphid multiplication.…”

Background: Field pea, Pisum sativum L. is an important winter-season pulse crop. It is subjected to damage by both field and storage insect pests and approximately 10-15 per cent reduction in yield was reported due to the infestation of different insect pests. Among these, pulse aphid (Aphis craccivora Koch.) affects plant physiology directly by removal of nutrients or indirectly by dispersal of various viral diseases. The present investigation has been aimed to study the seasonal fluctuations of aphids and their natural enemies as well as their correlation. Another objective was to know the effect of various weather parameters on pulse aphids and their natural enemies which ultimately would be helpful to develop a forewarning model.Methods: The field experiment was conducted at the A-B Block Farm of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal using two varieties of field pea (KPMR 935 and IFPD 122) during rabi seasons of two consecutive years of 2017-18 and 2018-19 following a Randomized Block Design with three replications. After recording the total population of both pests (nymphs and adults) and their natural enemies across the season, the mean population was worked out and used for correlation and regression studies along with the weather parameters. Result: Maximum aphid population was noticed during the peak pod formation stage of the crop irrespective of the varieties. The pest population was very strongly correlated with the incidence of coccinellid and ant population in both test varieties. Among the weather parameters, both maximum and minimum temperature and sunshine hour showed a positive correlation with the pest population and their natural enemies but relative humidity and rainfall showed a negative correlation. Regression studies indicated that temperature and relative humidity were the most influencing factors over the incidence of aphid in both the seasons.

“…The value of coefficient of determination R 2 revealed that the seasonal incidence of bean aphid was influenced by weather parameters to the extent of 86.70 per cent (Table 3). This result is in close conformity with the findings of Kataria and Kumar (2016) who studied the seasonal incidence of A. craccivora on bean crop. They reported that the maximum population of pest was seen in the month of January to March.…”

“…Regarding aphid abundance dynamics, relative humidity had higher explicative power than other climatic indicators (precipitations, temperature) [ 31 , 32 ]. Natural enemy abundance was more predictive of aphid abundance dynamics than aphid density [ 33 ], but less important than crop type [ 34 ] or climatic indicators [ 31 ].…”

(1) Although most past studies are based on static analyses of the pest regulation drivers, evidence shows that a greater focus on the temporal dynamics of these interactions is urgently required to develop more efficient strategies. (2) Focusing on aphids, we systematically reviewed (i) empirical knowledge on the drivers influencing the dynamics of aphid–natural enemy interactions and (ii) models developed to simulate temporal or spatio-temporal aphid dynamics. (3) Reviewed studies mainly focus on the abundance dynamics of aphids and their natural enemies, and on aphid population growth rates. The dynamics of parasitism and predation are rarely measured empirically, although it is often represented in models. Temperature is mostly positively correlated with aphid population growth rates. Plant phenology and landscape effects are poorly represented in models. (4) We propose a research agenda to progress towards models and empirical knowledge usable to design effective CBC strategies. We claim that crossover works between empirical and modeling community will help design new empirical settings based on simulation results and build more accurate and robust models integrating more key drivers of aphid dynamics. Such models, turned into decision support systems, are urgently needed by farmers and advisors in order to design effective integrated pest management.
