Baculoviruses may interact with parasitoids in the same host. A previous study has shown that infection of larvae with Spodoptera litura nucleopolyhedrovirus (SpltNPV) was deleterious to the survival and development of Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae). In this paper, the interactions between M. pulchricornis and Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) ...

One of the biological controls pest and plant disease is use enophytic bacteria. This study aimed to obtain endophytic bacterial from root tissue shallot plant, which potential as entomopathogens against larvae Spodoptera litura. research was arranged in a completely randomized design (CRD) with nine treatments consisting eight bacteria (isolation tissue) one control three replications. Paramet...

Movement, nictation, and infectivity of Steinernema carpocapsae strain All were compared for ensheathed (EnJ) and desheathed (DeJ) infective juveniles exposed to the insecticides acephate, dichlorvos, methomyl, oxamyl, or permethrin. Nematode response to various solutions included normal sinusoidal movement, uncoordinated motion, twitching, convulsion or formation of a pretzel shape, an inactiv...

Aerial traps, using combinations of color and attractive lures, are a critical tool for detecting and managing insect pest populations. Yet, despite improvements in trap efficacy, collection of nontarget species ("bycatch") plagues many insect pest surveys. Bycatch can influence survey effectiveness by reducing the available space for target species and increasing trap screening time, especiall...

Botanicals act not only as insecticides but also function as antifeedants, oviposition deterrents and ovicides. The present investigation reports on the antifeedant property of leaf components of Curculigo orchioides, Evolvulus alsinoides, Phyllanthus deblis, Swertia corymbosa and Zanthoxylum limonella. Solvent residues of these leaf components obtained from different solvent extracts dissolved...

Common mycorrhizal networks (CMNs) link multiple plants together. We hypothesized that CMNs can serve as an underground conduit for transferring herbivore-induced defence signals. We established CMN between two tomato plants in pots with mycorrhizal fungus Funneliformis mosseae, challenged a 'donor' plant with caterpillar Spodoptera litura, and investigated defence responses and insect resistan...

Terpenes are important defensive compounds against herbivores and pathogens. Here, we report the identification of a new monoterpene synthase gene, GmNES, from soybean. The transcription of GmNES was up-regulated in soybean plants that were infested with cotton leafworm (Prodenia litura), mechanically wounded or treated with salicylic acid (SA). Gas chromatography-mass spectrometry (GC-MS) anal...

Susceptibility of different biological stages of Spodoptera litura to various strains of entomopathogenic fungi was evaluated under laboratory conditions at Department of Entomology University of Agriculture, Faisalabad using the insect immersion method. Virulence potential of the entomopathogenic fungi varied with different biological stages of the insect pest. Eggs and larvae were comparative...
