Effects of Curcuma longa extracts on mortality and fecundity of Bactrocera zonata (Diptera: Tephritidae)

Abstract

The peach fruit fly, Bactrocera zonata, is a significant pest of fruit and vegetable crops in South East Asia and Pacific region. Ccontrol strategies of fruit flies, relying chiefly on insecticides, have serious environmental consequences, disturbing the agroecosystem as well as eliminating natural enemies. This study was oriented at exploring the potential of turmeric, Curcuma longa, extracts to control the peach fruit fly. Freshly emerged female adults of Bactrocera zonata were continuously fed for 16 days on diet containing 1000, 500 and 250 ppm of acetone extract of Curcuma longa separately in laboratory cages. The extract caused 85.00, 66.67 and 56.67 percent mortality at 1000, 500 and 250 ppm respectively. The surviving females were mated and allowed to reproduce on clean guava fruits in separate cages. The inhibition in pupal progeny was 67.90, 60.74 and 51.96 percent in the flies fed on 1000, 500 and 250 ppm, the inhibition observed in adult progeny was 84.68, 79.03 and 67.74 percent, respectively.Index terms: Turmeric, peach fruit fly, Bactrocera zonata, solvent extracts, mortality. RESUMOA mosca do pêssego, Bactrocera zonata, é uma importante praga das frutas e produtos hortícolas no Sudeste Asiático e Pacífico. As estratégias de controle de moscas-das-frutas, que se baseia principalmente no uso de inseticidas, têm consequências ambientais graves, perturbando o agroecossistema, bem como eliminando os inimigos naturais. Este estudo foi orientado a explorar as potencialidades dos extratos de açafrão Curcuma longa para controle de B. zonata. Após a emergência, adultos de fêmeas de B. zonata foram continuamente alimentados, durante 16 dias, com dieta contendo 1000, 500 e 250 ppm de extrato acetônico de C. longa separadamente em gaiolas no laboratório. O extrato causou 85,00, 66,67 e 56,67 % de mortalidade em 1000, 500 e 250 ppm, respectivamente. As fêmeas foram acasaladas e postas para ovipositar separadamente em goiabas dentro das gaiolas. A inibição na progênie pupal foi 67,90, 60,74 e 51,96 % nos insetos alimentados em 1000, 500 e 250 ppm, a inibição observada na progênie adulta foi 84,68, 79,03 e 67,74%, respectivamente.Termos para indexação: Cúrcuma, Bactrocera zonata, solventes de extracção e de mortalidade.

Turmeric powder and its derivatives from Curcuma longa rhizomes: Insecticidal effects on cabbage looper and the role of synergists

“…An artificial diet treated with acetonic solutions of extracts of C. longa rhizomes fed to the freshly emerged peach fruit flies, Bactrocera zonata (Saunders, 1841) (Diptera: Tephritidae) for 16 days at 1,000, 500 and 250 ppm produced 84.7, 79.0 and 67.7% mortality, respectively. Eggs deposited by the surviving females on clean guava fruits ( Psidium guajava L., Myrtales: Myrtaceae) in separate cages demonstrated 67.9, 60.7 and 51.9% pupal inhibition for the flies fed on 1,000, 500 and 250 ppm of C. longa extracts respectively50.…”

Adulticidal activity of some botanical extracts, commercial insecticides and their binary mixtures against the housefly, Musca domestica L.

“…In this respect, it may be convenient to mention that chloroform extract of Curcuma longa was reported to act as repellent to Tribolium castaneum (Herbst) adults (Abida et al, 2010), and to cause 85% mortality to the peach fruit fly, Bactrocera zonata (Diptera: Tephritidae), fed on diet containing 1000 ppm of acetone extract (Siddiqi et al, 2011). The addition of turmeric to sugar in our experiments didn't repel or kill the house fly adult, and may mask the odour of the tested toxicants.…”

Potential of Turmeric Extract and Its Fractions to Control Peach Fruit Fly (Diptera: Tephritidae)

“…TE has been already studied for multiple effects such as repellence, oviposition deterrence, fecundity suppression and mortality against Peach fruit fly Bactrocera zonata. Flies fed on diet containing TE at concentrations 250 and 500 ppm showed significantly higher mortality than those fed on control (Siddiqi et al, 2011;Siddiqi et al, 2006;Rehman et al, 2009). TE caused significantly high mortality to flies compared to the flies fed on the normal diet, the control.…”

“…Turmeric, (Curcuma longa) a subterranean perennial and tuberous herb widely cultivated in Pakistan and India, has been reported to contain potentially toxic components for different insect pests of stored grains (Siddiqi et al, 2011). Different extracts and their chemical fractions of turmeric have been found to contain strong repellent and toxic effects against different pests of stored rice and wheat (Siddiqi et al, 2011).…”

“…Different extracts and their chemical fractions of turmeric have been found to contain strong repellent and toxic effects against different pests of stored rice and wheat (Siddiqi et al, 2011). Acetone and petroleum ether extract of turmeric have been found to contain turmerones, which comprise of three important compounds, α-turmerone, β-turmerone and ar-turmerone ( Figure 1) (He et al, 1998, Singh et al, 2010.…”
