“…The sugar esters are contact insecticides with rapid knock-down ability, and are believed to kill their target insects by causing changes in the insect cuticle that interfere with the cuticle's desiccation protection properties and/or by suffocation, i.e., blocking the spiracles (Puterka et al 2003). Inhibition of feeding and oviposition in mites and whiteflies has also been documented (Neal et al 1994;Liu and Stansly 1995;Slocombe et al 2008). …”

“…Results further demonstrated that reducing sugars had positive interaction with mortality percentage of cotton mealybug. From the results it was clear that inhibition in attractiveness of P. solenopsis was also due to increased reducing sugar contents that serve as olfactory and gustatory stimuli and imbalanced nutrition for insect pest (Neal et al, 1994;Liu and Stansly, 1995;Hu et al, 2010).…”

“…Sucking insect pests including CMB are commonly attracted toward succulent plants that are enriched with chlorophyll (Tucker, 2004). Researchers demonstrated that herbivorous insectpest preference is due to imbalanced nutrition (Neal et al, 1994;Liu and Stansly, 1995). Although several researchers worked on the host range of P. solenopsis in Pakistan (Arif et al, 2009;Abbas et al, 2010) but the information regarding host-plants-preference (HPR) regulating biochemical factors (nutrients) in various host plants for P. solenopsis is quit lacking.…”

Dietary requirement and fitness of phytophagous insect pest depend upon the nutrient chemistry of host plant. The present research was carried out to investigate the association of host-plant-preference and mortality of Phenacoccus solenopsis first instar influenced by chemical characteristics of plant species. The experiment was carried out at (25 + 5ºC and 60 + 5% RH) in Integrated Pest Management Laboratory, University of Agriculture, Faisalabad, Pakistan during 2012. First instar exhibited maximum (attractiveness index = 0.75) toward Gossypium hirsutum followed by Trianthema portulacastrum (0.34) as compared Hibiscus rosa-chinensis (1.00) kept as standard. Mortality percentage of 1 st instar of CMB among 25 tested plant species ranged from 10% in cotton to 80% in Conyza bonariensis. Cluster analysis for biochemical traits showed that cluster-1 comprised of Lantana camara, H. rosa-sinensis, Helianthus annuus, Parthenium hysterophorus, Withania somnifera, Euphorbia prostrate, Portulaca oleracea, Solamum melongena, T. portulacastrum, G. hirsutum, Abelmoschus esculentus andCapsicum frutescens that had maximum attractiveness and less mortality. Cluster-2 Convolvulus arvensis, Eclipta prostrate, Amaranthus spinosus, Clerodendron inerme and Tribulus terrestris had medium whereas cluster-3 Launea nudicaulis, Chinopodium morale, C. album, Achyranthes aspera, C. bonariensis and Digera arvensis least attractiveness index but highest mortality. Principal component analysis (PCA) depicted that first three PCs expressed 83% of the total variability. Mortality of pest was negatively correlated with nitrogen and but positively with potassium, phosphorus, sodium, reducing sugar and total sugar. In conclusion, chemical contents affected attractiveness index and mortality of P. solenopsis; however there is need to explore allelochemicals imparting resistance against P. solenopsis.

“…This type of compounds are known to desiccate the insects, apparently by disrupting the cuticle function. Contact toxicity of these compounds has been demonstrated against soft‐bodied insects like aphids, mites, whiteflies, psyllids and also few lepidopteran larvae (Neal et al. 1994; Puterka and Severson 1995; Liu et al.…”

We report the toxicological effects of new series of biorational glycol esters and compare the efficacy with the known commercial sugar ester, sucrose octanoate. Ethylene glycol diesters were easy to prepare without any isomeric constraints and very safe compounds that were applied as sprays or as residues. The compounds were equally toxic to mustard aphid, Lipaphis erysimi nymphs and adults and the activity was significantly comparable with sucrose octanoate activity. In spray assays LC50 of various compounds ranged from 1.32 to 11.5 mg/ml and in residual assay the range was 20.3–51.4 μg/cm2. In residual assay, ethylene glycol di‐2‐ethylhexanoate (5) and dioctanoate (6) were as effective as sucrose octanoate. Structure activity relationship suggested that higher number of carbon chains in these two compounds may be playing a role in the stability of compounds under residual operation of the insecticide. Based on these results, glycol esters would be useful and easy to prepare biorational compounds in integrated pest management.
