HALOPHILA STIPULACEA (HYDROCHARITACEAE) EN LA LAGUNA DE YAPASCUA, PARQUE NACIONAL SAN ESTEBAN, CARABOBO, VENEZUELA Halophila stipulacea (Hydrocharitaceae) in Laguna de Yapascua, San Esteban National Park, Carabobo, Venezuela
ABSTRACTThe species Halophila stipulacea, considered invasive on the coasts of theCaribbean, was reported for the first time in Venezuela in 2014, in Vargas state.In this study, the distribution of this species in the country is extended to the coast of Carabobo state. Sampling was conducted in a seagrass bed in Laguna Yapascua(San Esteban National Park). …

Transcriptome differential co‐expression reveals distinct molecular response of fall‐armyworm strains to DIMBOA
Taking advantage of the recent publication from our group applying network analyses, I would like to present a last year publication in the Pest Management Science journal. We evaluated differential expression in the transcriptome of both midgut and fat body larval tissues of the two strains of the FAW reared on either DIMBOA‐enriched artificial diet …

Mechanisms behind polyphagia in a pest insect: Responses of Spodoptera frugiperda (J.E. Smith) strains to preferential and alternative larval host plants assessed with gene regulatory networks
This publication in Biochimica et Biophysica Acta (BBA) – Gene Regulatory Mechanisms is part of Natália Murad’s PhD in Universidade Estadual de Campinas, in Brazil, under mine and Dr. Marcelo Brandão’s supervision. A dataset of gene expression from FAW was used to understand how gene regulation is related to larval host plant preference. Transcriptomic data …

Comparisons of fall armyworm haplotypes between the Galápagos Islands and mainland Ecuador indicate limited migration to and between islands
The migration of the fall armyworm (Spodoptera frugiperda) is of topical interest because of its recent introduction and rapid dissemination throughout the Eastern Hemisphere. This study compares fall armyworm from island and mainland locations in Ecuador to estimate migration behavior. The Galápagos Islands is a province of Ecuador whose mainland coast lies approximately 1000 km …

Synergism and antagonism between Bacillus thuringiensis Vip3A and Cry1 proteins in Heliothis virescens, Diatraea saccharalis and Spodoptera frugiperda
Second generation Bt crops (insect resistant crops carrying Bacillus thuringiensis genes) combine more than one gene coding for insecticidal proteins in the same plant to provide a better control of agricultural pests. Some of the new combinations involve co-expression of cry and vip genes. Since Cry and Vip proteins have different midgut targets and possibly …

Spraying sugar solution in maize field attract natural enemies and increase parasitism on fall armyworm.
Cultural method of pest control make a less favourable environment to the pest and make a more favourable for their natural enemies. This method is the most widely adopted approaches in integrated pest management. As a part of cultural control, spraying sugar solution (10-20%) increases the population of certain parasitoids such as Campoletis flavicincta (Hymenoptera:Ichneumonidae), …

The effect of relative humidity on the development of the FAW egg parasitoid Telenomus remus Nixon
By: Alice dos Reis Fortes; Aloisio Coelho Jr.; José Roberto Postali Parra A possible natural enemy for biological control of the Fall Armyworm, Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae), is the wasp Telenomus remus Nixon, 1937 (Hymenoptera: Platygastridae), an egg parasite used …

Quality control is the key to rear efficient natural enemies for FAW
By: Pedro Holtz de Paula, Aloisio Coelho Jr., José Roberto P. Parra   The parasitoid wasp Telenomus remus is well known in the field of biological control. It is a potential agent to control Spodoptera frugiperda, with a few important examples of its use in South American countries (Colombia and Venezuela). In recent decades, several …

The influence of temperature on the development of FAW’s eggs parasitoid, Telenomus remus Nixon.
By: Marilia Corrêa Melo, Aloisio Coelho Jr., José R. P. Parra   The main hosts of Teleomus remus Nixon, 1937 (Hymenoptera: Plastygastridae) are eggs of lepidopterans of the family Noctuidae, especially species of Spodoptera. Eggs of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) and Spodoptera litura (Fabricius, 1775) (Lepidoptera: Noctuidae) are the most frequently …
