Biology of Brachymeria kamijoi Habu (Hymenoptera: Chalcididae), a pupal parasitoid of the coconut black-headed caterpillar, Opisina arenosella Walker (Lepidoptera: Xyloryctidae)
The coconut black-headed caterpillar, Opisina arenosella Walker (Lepidoptera: Xyloryctidae) has been one of the most serious defoliators of coconut plants in Vietnam. Brachymeria kamijoi Habu (Hymenoptera: Chalcididae) is a pupal parasitoid of O. arenosella with high percent parasitism and abundance in the coconut fields and appears to be a good biological control agent against the coconut black-headed caterpillar in Vietnam. This study was carried out at Entomology Laboratory, Faculty of Agronomy, Nong Lam University, Vietnam during 2020 – 2021 to determine some biological characteristics of B. kamijoi on O. arenosella at a constant temperature of 28 oC and a photoperiod of 12L: 8D. Total developmental time from egg to adult emergence was 13.8 days. The females laid a mean of 98.1 eggs during an average lifespan of 30.7 days. Fecundity peaked at a large range of age 7 -29 days. The results would contribute to the knowledge of the biology of B. kamijoi to optimize a mass-rearing system for a biological control programme against O. arenosella.
期刊介绍：
The Research on Crops is a peer-reviewed journal publishing original research papers, review articles and short communications in English on all basic and applied aspects of crop sciences, agricultural water management, agro-climatology, agroforestry, agronomy, crop production, crop protection, cropping systems, food science & technology, genetics & plant breeding, horticulture, plant & soil science, plant biotechnology, plant nutrition, post-harvest management of crops, seed science, soil management & tillage, vegetables, weed science, agricultural engineering, agri-business, agricultural economics and extension, etc. The aim of the journal is to provide a forum for the scientific community to publish their latest research findings.
The manuscripts submitted for publication should not contain data older than 4 years on the date of submission.
The articles submitted for publication in this journal should not be submitted elsewhere simultaneously for publication in another journal. These should not carry any copyright material without prior permission of copyright holder.
The articles should present a complete picture of the investigation made and should not be split into parts.
There is no prescribed limit regarding the number of pages in case of full-length articles. However, the authors are advised to keep the length of their articles from 4 to 10 full printed pages of the journal.
The articles should be divided into the sub-sections: ABSTRACT, INTRODUCTION, MATERIALS AND METHODS, RESULTS AND DISCUSSION, CONCLUSIONS, and REFERENCES. Tables and figures should be appended separately at the end.
