“…The similar incubation period of Trichogramma shows the eggs of Spodoptera and C. cephalonica being able to provide adequate nutrients to the larva of this parasitoid. Eggs of C. cephalonica (573.5 µm long × 346.1 µm wide, with a volume of 0.036 mm 3 ) and Spodoptera (454.9 µm long and 390.2 µm wide, with a volume of 0.036 mm 3 ), similar in size and volume (Cônsoli et al 1999), are suitable to allow Trichogramma to produce large and vigorous adults, resulting in a standard life cycle period and survival rate (Firake & Khan 2014;Edwin et al 2016). The higher number of females produced with eggs of both host species is beneficial in laboratory rearing for the release of this parasitoid (Brotodjojo & Walter 2006;Oliveira et al 2017).…”

“…Hexane washed eggs and untreated control eggs were considered as negative and positive controls, respectively. Egg card measuring 7 × 2 cm and holding approximately 80–100 eggs of YSB (Edwin, Vasantha‐Srinivasan, Ponsankar, Thanigaivel, & Selin‐Rani, 2016) was subjected to treatment through choice test as suggested by Murali Baskaran, Senthil‐Nathan et al (2018). The 40 egg cards (eight treatments and five replications) were arranged in equidistance in a round plastic container (8.5 cm diam; 5 cm height) by releasing the parasitoids at the centre at 1:6 ratio (parasitoids: treated host eggs).…”

The yellow stem borer (YSB), Scirpophaga incertulas, is a borer pest of low‐land rice in tropical regions of the world, reducing production and productivity. Chemical control of YSB is challenging and often less effective due to its cryptic larval feeding behaviour inside the rice culm. Biological suppression of YSB, using egg parasitoid, Trichogramma japonicum, has been well demonstrated. Kairomones, that are interspecific, play a vital role in deciding biocontrol efficiency of egg parasitoid against lepidopteran pests. However, the mechanisms involved in terms of emission of long‐ and short‐chain volatile chemicals from YSB and its by‐products and YSB damaged rice plants in attraction to T. japonicum to locate eggs of YSB are still poorly understood. In order to trace out the volatile compounds responsible for attraction of egg parasitoid, the hexane extract of YSB female whole body and acetone extract of YSB damaged rice culm were subject to GC‐MS analyses. Out of 20 chemicals, four chemicals belonging to carboxyl, alkane and saturated fatty acid [n‐hexadecanoic acid (palmitic acid), tetradecane, octadecane, n‐octadecanoic acid (stearic acid)] from female YSB hexane extract and three sesquiterpenoids (β pinene, α pinene and caryophyllene) from YSB damaged rice plant extracts were detected in greater concentrations. In laboratory assays with the synthetic form of seven chemicals, three, n‐hexadecanoic acid, n‐octadecanoic acid and octadecane, were promising in enhancing the parasitic activity of T. japonicum on YSB eggs from 26.4% to 92.6% at 200 ppm, 27.3% to 96.5% at 500 ppm and 23.6% to 82.8% at 500 ppm, respectively, in contrast to untreated eggs (87.3% at 7th day after exposure) and hexane washed eggs (16.7% at 7th day after exposure). Evaluation of these compounds revealed the key chemical cues of biocontrol potential (n‐hexadecanoic acid, n‐octadecanoic acid and octadecane) for enhancing egg parasitism activity of T. japonicum on YSB eggs.

“…It can attack the eggs of more than 200 species of insects. Therefore, the large-scale breeding and release of T. chilonis is an economically viable method for the control of a variety of lepidopteran pests (Edwin et al 2016). In China, T. chilonis is widely distributed and is employed in integrated pest management for maize, rice, sugarcane and other crops (Yi et al 2014).…”

Trichogramma chilonis Ishii is an important natural enemy of several lepidopterous pests on crops. In this study, we sequenced the complete mitochondrial genome of T. chilonis (GenBank accession number MW789210). The length of the complete mitochondrial genome was 16,147 bp, containing 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and a non-coding control region. The overall base composition of the genome in descending order was 44.8% T, 41.8% A, 9.0% G and 4.5% C, with a significant AT bias of 86.6%. Phylogenetic analysis indicated that T. chilonis had a close relationship with Trichogramma ostriniae.
