“…Host plant resistance (HPR) offers an opportunity for effective control of sucking insect pests as an economically and environmentally safe strategy in the GM cotton system (Khan et al 2003). Khalil et al (2017) studied the role of some morphological plant traits against sucking insect pest complex in six genotypes of cotton. They identified the negative response of whitefly to gossypol glands on leaf lamina, midrib and vein.…”

Background Sucking insect pests cause severe damage to cotton crop production. The development of insect resistant cotton cultivars is one of the most effective measures in curtailing the yield losses. Considering the role of morphological and biochemical host plant resistance (HPR) traits in plant defense, 12 cotton genotypes/varieties were evaluated for leaf area, leaf glanding, total soluble sugars, total soluble proteins, total phenolics, tannin and total flavonoids against fluctuating populations of whitefly, thrips and jassid under field conditions. Results The population of these insects fluctuated during the growing season and remained above threshold level (whitefly > 5, thrips > (8–10), or jassid > 1 per leaf) during late June and early July. Strong and negative association of whitefly (r = − 0.825) and jassid (r = − 0.929) with seed cotton yield was observed. Mean population of insects were the highest in Glandless-1 followed by NIA-82 and NIA-M30. NIAB-Kiran followed by NIAB-878 and Sadori were the most resistant, with the mean population of 1.41, 1.60, 1.66 (whitefly); 2.24, 2.32, 2.53 (thrips) and 0.37, 0.31, 0.36 (jassid), respectively. The resistant variety NIAB-Kiran showed less soluble sugars (8.54 mg·g− 1), soluble proteins (27.11 mg·g− 1) and more phenolic (36.56 mg·g− 1) and flavonoids (13.10 mg·g− 1) as compared with the susceptible check Glandless-1. Moreover, all insect populations were positively correlated with total soluble sugars and proteins. Whitefly populations exhibited negative response to leaf gossypol glands, total phenolics, tannins and flavonoids. The thrips and jassid populations had a significant and negative correlation with these four biochemical HPR traits. Conclusion The identified resistant resources and HPR traits can be deployed against sucking insect pests’ complex in future breeding programs of developing insect resistant cotton varieties.

“…Low leaf area is associated with an increased likelihood of disappearance of eggs and nymphs due to increased exposure (Sippell et al, 1987;Katono et al, unpubl. ) while relatively tall plants are not preferred by adults (Murugesan & Kavitha, 2010;Khalil et al, 2015;Katono et al, unpubl. ), thus reducing B. tabaci numbers that farmers desire.…”

In Sub-Saharan Africa, cassava is considered a staple crop that is highly resilient to climate change (Nweke et al., 2002; Jarvis et al., 2012; Maruthi et al., 2017).Though many mortality factors are known to impact B. tabaci fi eld populations (Gerling et al., 2001; Naranjo & Ellsworth, 2005), there is limited information on the rates of mortality associated with specifi c causes of death, especially in light of the different B. tabaci species currently described. Age-specifi c life tables for insects under fi eld conditions provide critical information for a given cohort of individuals thus helps to identify mortality factors responsible for population regulation (Choudhury et al., 2013). Life tables have previously been used to study the

“…It added a remarkable value about 8.2% in agriculture and round about 3.2% in gross domestic product (GDP). Two thirds of Pakistan's earnings depends upon the export of cotton products, mostly through textiles that adds round $2.5 billion in the country earning; while hundreds of textile mills and ginning factories are hugely depending upon cotton cultivation [2]. There are many factors responsible for low cotton yield but insects are ranked at the top of biotic agents that not only deteriorate the quality of cotton but also reduce the yield [3].…”

Cotton is one of the major cash crops of Pakistan. A collaborative study was conducted by Sangtani Women Development Organization, Ghazi University Dera Ghazi Khan and Women University Multan under Better Cotton Initiative project to provide an eco-friendly and economical control of white fly, aphid, jassid and thrips. For this purpose, ten locally available leaves of the plant trees were selected and their extracts were made with the help of methanol. White fly population is studied and when it's reached at Economic Threshold Level, the extract of plant leaves were sprayed at 2%, 4% and 6% concentration. The data was taken after 24, 48 and 72 hours of spray to check the efficiency of different plant extracts at different concentration. After data analysis result were incorporated and our results shows that And when the data of these tested plants were analysis, it is clear from our data that at 2% concentration all tested plants extract showed good potential as an insecticide against Bemasia tabaci but among these Delbergia sissoo showed excellent mortality rate of B. tabaci When these plants were tested at 4% concentration then our results reflect that Melia azedarach and Eculypatus camaldulensis are most effective against B. tabaci and at 6% concentration Calotropis gigantean, Melia azedarach and E. camaldulensis have the most effective insecticidal effect against adult population of the white fly of cotton crop followed by Accaia nilotica and Black serruss. Plant extract have the potential to become an integral part of Integrated Pest management (IPM) as a repellent and as well as an insecticide.
