Evaluation of Insecticides Targeting Control of <i>Helicoverpa armigera</i> (Hubner) (Lepidoptera: Noctuidae)

Abstract

Insecticides from different chemical groups were tested by laboratory bioassay to verify the percentage mortality of Helicoverpa armigera (Hubner 1808) (Lepidoptera: Noctuidae). The experiment was conducted in the Crop Science laboratory-Prof. CinobelinaElvas Campus-UFPI, Bom Jesus, PI, from January to June, 2013. The populations utilized came from the University's own insect breeding laboratories. Third instar larvae of H. armigera were used to conduct the bioassay. The experimental design was fully randomized, with 13 treatments and four replications. Five larvae were used per replication, with 12 insecticides from 9 different chemical groups and a control. Each treatment consisted of three doses. The methods of application used were topical contact and ingestion in artificial diet. According to the results the percentage mortality of H. armigera larvae varied among the treatments. The results demonstrated that chlorpyrifos and spinosad were effective against third instar H. armigera larvae both on contact and by ingestion. Flubendiamide, acephate, methomyl, Bacillus thuringiensis, dimethoate, chlorantraniliprole and fipronil had good responses to control of H. armigera.

Potential of antranilic diamides applied in seeds of soybeans with and without cry1ac protein for Helicoverpa armigera caterpillar control

“…On the other hand, confirm the efficiency of the active ingredient for the control of this pest, as already seen in spraying of plant leaves (Wakil et al, 2012;Carneiro et al, 2014;Misra, 2015).…”

“…The inability of fipronil in prevent foliar consumption by H. armigera larvae indicates a limitation of this active ingredient, at the dose tested, when applied to soybean seeds. Its toxic effect on caterpillars (Colliot et al, 1992), including H. armigera (Carneiro et al, 2014) has been observed when sprayed in soybean foliage.…”

Evaluation of flubendiamide‐induced mitochondrial dysfunction and metabolic changes in Helicoverpa armigera (Hubner)

“…Mitochondria are more susceptible to pharmacological and pesticides compounds and are the best source to study biomembrane interactions (Chakraborty, Chakraborty, Raha, Mandal, & Sarkar, 2007). Studies were carried out to evaluate the effects of methyl parathion (OP) and carbofuran (carbamate) on H. armigera mitochondrial bioenergetics (Akbar, Sharma, Jayalakshmi, & Sreeramulu, 2012a;Carneiro et al, 2014;Srinivas et al, 2004). Pyrethroids were found to induce mitochondrial dysfunction in rat liver mitochondria (Gassner, Wüthrich, Schooltysik, & Solioz, 1997;Kamboj, Kumar, Kamboj, & Sandhir, 2008;Kumar et al, 2015;Mehta, Verma, & Srivastava, 2009).…”

“…Helicoverpa armigera (Noctuidae: Lepidoptera), commonly known as cotton bollworm/legume pod borer, is a devastating polyphagous pest and a major constraint to crop production in Asia, Africa, Australia, and Mediterranean Europe for the last four to five decades (Han et al., ; Sharma, ). It represents a challenge for agricultural production worldwide because of its feeding on more than 200 different species of economically important crops, such as soybeans, cotton, sorghum, corn, sunflower, peanuts, chickpea, pigeon pea, groundnut, maize, and vegetables like beans, tomatoes, peppers, and even forest trees, causing an average of $10,000 million annual loss globally (Akbar, Sharma, Jayalakshmi, & Sreeramulu, ; Ameta & Bunker, ; Carneiro et al., ). Most of the lepidopteran insects including H. armigera have developed resistance against organophosphates (OPs), carbamates, and pyrethroids (Akbar, Aurade, Sharma, & Sreeramulu, ; Armes, Jadhav, and DeSouza, ; Srinivas, Udikeri, Jayalaxmi, & Sreeramulu, ).…”

Emamectin benzoate: Potential larvicide and antifeedant agent against cotton Boll worm Helicoverpa armigera (Lepidoptera: Noctuidae)

“…Various conventional synthetic insecticides have been used for the control of this pest; such as organochlorines -endosulfan; organophosphates -chlorpyrifos; carbamates -carbaryl; pyrethroids -cypermethrin, lambda-cyhalothrin, deltamethrin; microbialchlorfenapyr, neonicotinoids -imidacloprid; indoxacarb, etc. (Forrester et al, 1993;Ishtiaq et al, 2012;Carneiro et al, 2014). Almost 30% of the pesticides are targeted against H. armigera which results in the consumption of a major proportion of total insecticides in the market just to control this pest (Ahmad, 2007;Lammers and Macleod, 2007).…”
