“…All the germplasms revealed high abundance of jassid in the late growing period of the study which might be associated with the increased temperature at the end of the season. The result is in agreement with that of Shipa et al (2021), who found the abundance of jassid on the tested cotton varieties as having significant positive correlation with temperature. The mean abundances of jassid on the germplasm differed significantly and the highest (11.7 ± 1.3 jassids/leaf) and the lowest (3.7 ± 0.8 jassids/leaf) results were found on BARI Begun-5 and BARI Begun-6, respectively (Figure 1).…”

The tropical vegetable, brinjal is cultivated throughout the year in Bangladesh but the crop is infested by a number of insects including jassid. This study investigated the effects of different biophysical and biochemical characteristics of twelve brinjal germplasms on the abundance and infestation of jassid. The experiment was conducted during September 2018 to March 2019 in Gazipur, Bangladesh with twelve brinjal germplasms namely BD-7320, BD-7328, BD-9952, BD-10154, BD-10158, BARI Begun-1, BARI Begun-4, BARI Begun-5, BARI Begun- 6, BARI Begun-7, BARI Begun-8 and BARI Begun-9. The incidence of jassid was recorded from 3rd December to 26th March, and the lowest population was found on BARI Begun- 6. Among the biophysical traits, plant height, number of branch and leaf per plant, and leaf area exerted significant positive correlation; whereas trichome on lower and upper surfaces of leaf, spine per stem and leaf showed significant negative correlation with the abundance of jassid. On the other hand, moisture, reducing sugar, total sugar and protein content of the leaves and fruits, chlorophyll content of the leaves exerts significant positive correlation but ash and pH contents of the leaves and fruits were negatively correlated with the abundance of jassid. Jassids showed the lowest level of leaf infestation on BARI Begun-6, which could be for further analysis to develop jassid resistant brinjal. SAARC J. Agric., 19(1): 81-91 (2021)

“…This consistency underscores the importance of temperature regulation in shaping pest populations and aligns with previous research highlighting the sensitivity of aphid species to temperature fluctuations. However, the current study expands upon these findings by elucidating the nuanced impacts of additional weather parameters, such as maximum temperature, minimum temperature, total rainfall, and relative humidity, which collectively account for a substantial portion of the variance in Brachycaudus helichrysi [48], cotton aphid [49], Lipaphis erysimi [50], Myzus persicae [17], and wheat aphid [51]. The pivotal year of 2022, marked by the absence of A. fabae, contrasts with previous studies that consistently reported the presence of aphids in faba bean fields.…”

Faba beans (Vicia faba L.) face threats from pests like the black bean aphid (Aphis fabae S.). By understanding the intricate interactions between environmental factors and pest dynamics, we aim to enhance pest management practices in leguminous crop production for improved efficiency and sustainability. A field experiment spanning three growing seasons (2021–2023) explored the link between meteorological parameters and A. fabae abundance in V. faba. Weekly field inspections documented aphid levels alongside concurrent meteorological data. Correlation and multiple linear regression were used to evaluate these relationships. Aphid infestation varied annually, appearing in 2021 and 2023 but not in 2022. Peak density aligned with specific growth stages, indicating temporal variability. In 2023, a significant surge of 1157.4% to 2126.0% compared to 2021 levels highlighted population dynamics in response to environmental factors. Negative correlations with total rainfall were consistent in both years, while positive correlations with maximum temperature and relative humidity were observed. Multiple linear regression attributed 67.1% to 99.9% of aphid abundance variance to the meteorological parameters, emphasizing their role in predicting aphid populations. Our study sheds light on the complex relationship between meteorological parameters and A. fabae dynamics, offering valuable insights into factors impacting aphid abundance in V. faba.
