Egg parasitoids
-
Ebook "Egg parasitoids in agroecosystems with emphasis on Trichogramma" with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations.

Differences in the expression of genes present in both sexes are assumed to contribute to sex differences including behavioural, physiological and morphological dimorphisms. For enriching our knowledge of gender differences in an important egg parasitoid wasp, Anastatus disparis (Hymenoptera: Eupelmidae), sex-biased differences in gene expression were investigated using Illumina-based transcriptomic analysis.

Rice, (Oryza sativa L.), is liable to infestation with several insect pests, from which the rice stem borer, Scirpophaga incertulas (Walker) (Lepidoptera: Pyralidae) is one of the most destructive and widely distributed throughout the india. To determine the extent of parasitization of yellow stemborer egg masses, the egg masses were randomly collected at weekly intervals depending on the availability from rice fields, and brought to the laboratory for collection of emerging parasites.

This survey was conducted in rice field during kharif season of year 2017 at Pusa farm of Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar. The important egg parasitoids of major insect pest of rice were observed for stem borer egg mass and leaf folder egg mass. The dominant egg parasitoid actively present throughout the kharif season on stem borer eggs was Trichogramma japonicum, it was found most active during the 33rd standard week of August 51.42% and least active in the 30th standard week of July 3.03%.

A field experiment was conducted during the Kharif seasons 2012 and 2013 at Students Instructional Farm and Vegetable Research Farm, NDUA&T, Kumarganj, Faizabad (UP) to find out the natural enemies of shoot and fruit borer in okra. The eggs parasitoids Trichogramma chilonis, parasitized 6.25 and 7.40% egg of Earias spp Kharif, 2012 and Kharif, 2012 respectively. Among predators, maximum population of Coccinellids 4.36 and 4.05 adult per 5 plants was recorded in third week of August.

An extensive survey for the diversity of mymarid fauna, internal solitary egg parasitoid was conducted in different agroecosystems of Tamil Nadu, during August 2018 – April, 2019. A total number of 1901 mymarid specimens were collected by using yellow pan traps in different cropping ecosystems viz., mango, sapota, grapes, brinjal, red gram, cotton, coffee, medicinal plants, and marigold. The mymarids were identified upto generic level.

Of the total nine hymenopteran parasitic wasps revealed from rice paddy in Sisophon, Northwest Cambodia, there are six larval braconid parasitoids: Apanteles cypris Nixon, Bracon onukii Watanabe, Dolochogenidea agilis Ashmead, Pentatermus striatus (Szepligeti), Taiwanhormius sp., Tropobracon luteus Cameron (Braconidae); two pupal ichneumonid species: Casinaria colacae Sonan, Xanthopimla flavolineata Cameron (Ichneumonidae), and one egg scelionid parasitoid: Telenomus rowani Gahan (Scelionidae). Additionally, all the species were recorded for the first time for Cambodia’s fauna.

In this study we evaluated the dispersal ability of Trichogramma evanescens in field and storage conditions. In field studies we tested the effects of plant structure on the dispersal ability of T. evanescens from release points. Both in a corn field and on grapevines the level of parasitism was negatively correlated with distance when the host eggs were located away from the release point.

The egg-larval parasitoid Chelonus oculator Panzer (Hymenoptera: Braconidae) is a solitary endoparasitoid. The effect of superparasitism on the development of C. oculator was investigated on a host, Cadra cautella Walker (Lepidoptera: Pyralidae) at 25 °C, 60%-70% R.H., and 16:8 h (L:D) photoperiod.
