Background: Cultivation of cotton, the staple fiber crop, is expanding in Bangladesh. The crop suffers from the infestation of the sucking insect pests i.e., aphid and jassid. This study investigated the physiomorphic traits, yield and quality of cotton plants regarding the abundance of aphid and jassid.Methods: The study was conducted in Gazipur, Bangladesh with the cotton varieties namely CB12, CB13, CB14, CB15 and HC1. Abundance of the insect pests was recorded through weekly inspection of the field.Result: The tested cotton varieties showed differences in physiomorphic traits, yield and quality attributes. Statistically, aphid and jassid showed the lowest abundance on CB14 and HC1 varieties, respectively and the variety CB14 revealed the lowest plant deformities and resulted the highest yield and quality attributes. Aphid and jassid populations revealed a negative correlation with leaf trichomes and phytochemical contents but showed a positive correlation with the number of leaves plant-1.

Amin et al (2017) showed that weather parameters had insignificant effect on the population abundance of aphid on cotton plant in Bangladesh. They also reported that the aphid population started to build up at the end of October when the maximum and minimum temperatures decreased, the relative humidity slightly declined, and there was little rainfall.…”

Mustard (Brassica juncea) variety BARI Shorisha-11 was cultivated during September 2016 to March 2017 in Gazipur, Bangladesh to find out the population dynamics of aphid and its infestation level on mustard. The aphid Lipaphis erysimi (Homoptera: Aphididae) was abundant in the field and caused infestation. The population of aphid in the mustard field showed fluctuation and reached to the peak at 22 December which was 289 per plant. Inflorescence had significantly higher level of infestation compared to individual siliqua and leaf. The daily mean temperature had significant negative, light intensity had insignificant negative and relative humidity had insignificant positive correlation with the abundance of aphid. The multiple linear regression analysis showed that the weather parameters namely temperature, light intensity and relative humidity individually as well as combindly contributed on the abundance of aphid, but the temperature had greater effect than other factors.Bangladesh J. Agril. Res. 43(4): 611-618, December 2018

“…The abundance and infestation of herbivore pest species vary with geographical location, climatic conditions, and host plant availability (Hidalgo et al 2013;Razdoburdin et al 2014). The host plant's growth stage, physiomorphic traits, and prevalent natural enemies also affect pest population dynamics (Amin et al 2011(Amin et al , 2015(Amin et al , 2017. Abiotic factors such as temperature, humidity, and rainfall can interrupt the growth, development, reproduction, foraging, distribution, and feeding behavior of herbivore pests, in turn impacting the frequency and intensity of pest infestations (Amin et al 2017(Amin et al , 2019.…”

to investigate the effects of temperature, relative humidity, and rainfall on the incidence of sucking pests (thrips, aphids, and red spider mites) on roses. The results showed that the thrips population started to increase in the first week of January, gradually increasing and reaching its maximum (2.6 ± 0.2 individuals/flower) in the first week of February, and then declining. The aphid population started to increase in the second week of November, reached its peak (8.4 ± 0.6 individuals/shoot) in the last week of December, and then declining. The mite population started increasing in the second week of December, increased continuously until its peak (8.4 ± 0.4 individuals/shoot) in the first week of March, and then declining. The populations of thrips, aphids, and mites persisted until the third week of April, the third week of May, and the first week of April, respectively. Daily mean temperature and rainfall were negatively correlated with the increase in the thrips and aphid populations, while relative humidity was positively correlated with it; however, these correlations were not significant. The mite population had a significant positive correlation with temperature and a non-significant negative correlation with relative humidity and rainfall. Multiple linear regression analysis showed that weather variables together predicted 34%, 53.1%, and 41.7% of thrips, aphid, and mite abundance on rose plants.
