Abstract

Sap-sucking insect pests have been a severe threat to horticultural and agricultural crops all over the world. Asian citrus psyllid Diaphorina citri Kuwayama (Psyllidae: Hemiptera) and cotton aphid Aphis gossypii Glover (Aphididae: Hemiptera) are destructive sap-sucking pests of citrus and cotton, respectively. Extensive use of persistent synthetic insecticides against these pests poses issues of environmental contaminations and health hazards and suggests looking for alternate biorational plant protection measures such as botanical pesticides. This study evaluated the potential toxicity of acetone extracts of 40 indigenous plant species of Soon valley and surrounding salt range (Punjab, Pakistan) against D. citri and A. gossypii using standard twig-dip and leaf-dip bioassay methods, respectively. Results of initial screening bioassay showed the highest mortality of D. citri by 10% extracts of Mentha longifolia (L.) Huds. (93%), Melilotus officinalis (L.) Pall. (91%), Nerium indicum Mill. (89%), Datura alba L. (88%) and Salvia officinalis L. (81%). Second bioassay conducted against A. gossypii using different concentrations (5, 10, 20 and 40%) of the most effective botanical extracts revealed that the extract of S. officinalis was most toxic (LC50 = 18.59%), followed by N. indicum (LC50 = 20.27%) and M. longifolia (LC50 = 20.73%). Similar trend of effectiveness was observed regarding their LT50 values. Overall study results demonstrated the biocidal potential of the extracts of indigenous plant species of Soon valley against D. citri and A. gossypii, and suggest their further biochemical characterization and practical implication in future IPM programs against these and other sap-feeding insect pests.

Abstract

Leafworm Spodoptera litura Fabricius is a highly polyphagous pest of food, forage, vegetable and horticultural crops. This sporadic species is becoming an emerging threat to the potato crop in central Punjab and is being evidenced infesting potato crop in Sargodha, Faisalabad and Okara districts. This in-vitro study assessed the comparative feeding preference, food consumption and utilization rates and larval development of S. litura on different white and red skinned potato cultivars. Feeding bioassays revealed that all parameters including leaf weight loss, larval weight gain, relative food consumption and growth rates and conversion efficiency of the ingested food were statistically significant (P ≤ 0.05). Exotic potato cultivars Diamant, Desiree and Asterix exhibited maximum leaf consumption and larval weight gain (i.e. 264.61, 259.37 and 233.01 mg and 121.46, 120.17, 120.13 mg, respectively) concomitantly with maximum values of relative growth rate (RGR), relative consumption rate (RCR) and ingested food conversion efficiency (ECI). Cultivars Lady Rosetta, Cardinal, Ajax, Kuroda and Sante exhibited intermediate values. Minimum feeding preference and susceptibility to S. litura was shown by the native potato cultivars Faisalabad Red and Faisalabad White with minimum food consumption, larval weight gain, RGR, RCR and ECI values, and hence are recommended to indigenous potato growers for commercial cultivation in areas where S. litura threatens potato crop.
