Research Notes
The fall armyworm (FAW) Spodoptera frugiperda (Smith) is a major agricultural pest in Americas, Africa and Asia. Egg masses are covered with scale layers and the various scale layer thicknesses of these masses can affect parasitoids efficiency. The present study aimed to determine dynamics of the scale thickness on egg masses and its effect on Trichogramma parasitoid …

Trap cropping is a promising, environmentally sound approach to manage pests in agricultural and forest systems through exploiting insect preferences for certain host plants. In a wide range of cropping systems, trap cropping greatly reduces damage, disease and insecticide use on the main crops, and thus increases the yield of the main crop. In a …

Spodoptera frugiperda is a major worldwide migratory agricultural pest, ranking first in the list of crop pests and diseases of China. It invaded China in 2019 and was first discovered in Liaoning Province in 2020. A large number of studies have shown that reduced target sensitivity is the main mechanism of the insect pest’s high-level …

In July 2019, we found a species of egg parasitoid wasp emerged from Spodoptera frugiperda eggs collected in southeast of Guizhou province. This parasitoid species was identified by molecular method as Telenomus remus. To test the parasitic efficacy of T. remus against S. frugiperda and S. litura eggs, we investigated the parasitic rates, offspring number per host eggs, body size, …

Research Notes
Telenomus remus has been viewed as an effective biological control agent against Spodoptera frugiperda eggs. The investigation of basic biological characteristics of T. remus will supply the reference for the mass rearing and application of T. remus. In this study, we described the characteristics of parasitic behavior of T. remus females and the morphological characteristics of T. remus females and …

Fall armyworm Spodoptera frugiperda ( Smith) is a new invasive pest causing serious damages in China. Among egg parasitoids，Trichogramma are the dominant biological control agents that has been applied to control lepidopteran pests of crops，vegetables and forests worldwide. To evaluate the possibility and efficiency of local Trichogramma species of northeastern China on S. frugiperda eggs，we …

Research Notes
Trichogramma species make up one of the most commonly used groups of natural enemies for biological control programs worldwide, and have been the best natural enemies suitable for mass production with low cost. Since the 1960s, improved mass production of Trichogramma and better augmentative release methods to suppress agricultural pests have been achieved. We review …
