“…The percent fruit infestation and larval density were significantly lower in resistant varieties/ genotypes and higher in susceptible varieties/ genotypes of muskmelon. Numerous studies have shown that varieties/ genotypes of the same species could differ significantly in their resistance to insect pests (Dhillon et al 2005a;Gogi et al 2009;Sarfraz et al 2006;Weems & Heppner 2001) and it is caused by biochemical traits of plants.…”

“…The Japanese liqueur Midori is flavored with muskmelon. Plants are generally exposed to a variety of biotic and abiotic factors that may alter their genotypic and/or phenotypic properties resulting in different mechanisms of resistance which enable plants to avoid, tolerate or recover from the effects of pest attacks (Gogi et al 2010b;Pedigo 1996;Sarfraz et al 2006). Such mechanisms of plant resistance have been effectively used against insect pests in many field and horticultural crops (Dhillon et al 2005b;Gogi et al 2010a;Kogan 1982;Sarfraz et al 2007).…”

“…Mechanisms of resistance in plants are either constitutive or induced (Karban & Agrawal 2002;Painter 1951;Traw & Dawson 2002) and are grouped into three main categories: antixenosis, antibiosis and tolerance (Painter 1951). Plants responsible for antibiosis resistance may cause reduced insect survival, prolonged developmental time, decreased size and reduced fitness of new generation adults (Gogi et al 2010b;Painter 1951;Sarfraz et al 2006Sarfraz et al , 2007.…”

Host plant resistance is an important component for management of the melon fruit fly, Bactrocera cucurbitae (Coquillett), owing to difficulties associated with its chemical and biological control. Various biochemical traits including total sugar, reducing sugar, non-reducing sugar, tannins, phenols, alkaloids, flavinoid and pH contents of fruit were studied on 11varieties/ genotypes of muskmelon, Cucumis melo L., in relation to resistance against B. cucurbitae under field conditions. Significant differences were found in tested varieties/ genotypes for fruit infestation and larval density per fruit. AHMM/BR-1, RM-50 and AHMM/BR-8 were the most resistant; MHY-5, Durgapura Madhu and Pusa Sarabati were moderately resistant; AHMM/BR-13, Pusa Madhuras and Arka Jeet were susceptible; whereas Arka Rajhans and GMM-3 were the highly susceptible varieties/ genotypes to fruit fly in both seasons, 2011 and 2012. The larval density per fruit increased with an increase in percent fruit infestation and there was a significant positive correlation (r = 0.97) between percent fruit infestation and larval density per fruit. Total sugar, reducing sugar, non-reducing sugar and pH were lowest in resistant and highest in susceptible varieties/ genotypes, whereas tannins, phenols, alkaloids and flavinoid contents were highest in resistant and lowest in susceptible varieties/ genotypes. Total alkaloid and pH contents explained 97.96% of the total variation in fruit fly infestation and 92.83% of the total variation in larval density per fruit due to alkaloids and total sugar contents.

“…Las hembras eligen sitios de ovoposición adecuados y asociados a condiciones de temperatura y humedad favorables, y a estímulos visuales, físicos y químicos provenientes de las plantas (Sarfraz, Dosdall y Keddie, 2006;Dosdall, 2014). Entre las etapas del ciclo de vida, el primer estadio larval de la P. xylostella es el que produce el mayor impacto sobre las plantas crucíferas.…”

La Plutella xylostella (L.) es un insecto plaga que afecta principalmente los cultivos de brasicáceas o crucíferas como el repollo, coliflor, brócoli y rábano, entre otros. Las limitaciones del rendimiento y calidad de estos cultivos se deben principalmente al difícil manejo de esta plaga. En la actualidad, para controlar la P. xylostella se utilizan insecticidas de síntesis química, como piretroides, carbamatos u organofosforados, los cuales tienen acción inmediata pero causan efectos adversos en la salud y en el ambiente. Adicionalmente, la ausencia de enemigos naturales capaces de controlar a sus poblaciones, y su resistencia a numerosos insecticidas convencionales hacen que este insecto se establezca rápidamente en áreas productoras de brasicáceas. Se calcula que los costos mundiales asociados al control de la P. xylostella, sumados a las pérdidas en la producción agrícola, están entre cuatro y cinco billones de dólares anuales.Se han propuesto alternativas seguras, efectivas y de menor impacto ambiental, como el control biológico, que permite la producción sostenible de los cultivos de brasicáceas. La industria agrícola y forestal reconoce a la bacteria entomopatógena Bacillus thuringiensis (Bt) como una buena alternativa biológica a los insecticidas químicos, puesto que es inocua sobre el ambiente y su toxicidad es altamente selectiva, ligada a su estrecho rango de especificidad sobre diferentes insectos plaga de los órdenes Lepidóptera, Coleóptera y Díptera. En esta revisión se presentan las posibilidades actuales que se pueden emplear para el control de la P. xylostella utilizando modelos investigativos basados en ensayos biológicos con Bt. Dichas posibilidades buscan superar las desventajas existentes en relación con la plaga P. xylostella y los cultivos de brasicáceas, además de entender la fisiología de Bt bajo condiciones que permitan incrementar la eficacia en el control biológico.

“…Diamondback moth, Plutella xylostella (L.) (Lepidoptera, Plutellidae), is a serious and important pest of cruciferous plants worldwide (Talekar and Shelton 1993;Sarfraz et al 2006;Li et al 2016). Plutella xylostella occurs annually throughout different regions of Iran wherever cruciferous crops are grown and can cause substantial crop losses during outbreak years (Keyhanian et al 2005).…”

Bacillus thuringiensis is a Gram-positive, aerobic, facultative anaerobic and endosporeforming bacterium. Different strains of this species have the ability to produce parasporal crystalline inclusions which are toxic to larvae of different insect orders and other invertebrates and cause rapid death of the host. To determine the importance of this species in microbial control, we collected native strains and studied their virulence on the diamondback moth, Plutella xylostella. More than 148 samples were collected from Alborz, Guilan and Mazandaran Provinces. Experimental samples, including soil samples from forests, fruit gardens, agricultural fields, diseased and dead larvae, were transferred to a laboratory in sterile plastic containers. For evaluating B. thuringiensis isolates virulence, a cabbage leaf dip method with 10 6 cell ⋅ ml -1 concentration of various Bt isolates was applied to diamondback moths. Larval mortality was recorded 72 h after treatment. Based on bioassay results, all isolates were classified into three high, medium and low virulence groups. Protein level characterization based on the SDS-PAGE gel analysis showed that two isolates from a high virulence group have proteins of high molecular masses of 121 and 109 kDa. Results revealed that there is a positive correlation between protein masses and virulence of isolates. In addition, this research introduced nine strains that are highly toxic to P. xylostella and would be valuable as insecticidal agents for controlling lepidopteran pests.
