“…An early distribution record is that in Pierce's (1909) revision of Strepsiptera in which he reported H. australensis from Queensland, Australia, hence the specific name. Halictophagus spectrus Yang 1964, commonly reported as a parasite of Cofana spectra in Asia, and H. helleri Kinzelbach 1971, are both synonyms of H. australensis (Kathirithamby, 1992).…”

Three tests were conducted over a 2-year period in lowland irrigated rice fields on the WARDA Research Station at Bouaké, Côte d'Ivoire, to obtain information on the strepsipteran parasitism of white leafhoppers, Cofana spectra and C. unimaculata. Rice cultivars were sampled with a sweep net to collect leafhoppers for determination of the relative abundance of the two leafhopper species and the effect of rice cultivar and rice crop age on the leafhopper populations and percent strepsipteran parasitism. Dissections of the leafhoppers were made to determine the relative number of the various parasitic stages in the leafhoppers. Cofana unimaculata populations were higher than those of C. spectra while C. spectra parasitism by Halictophagus australensis Perkins (Strepsiptera: Halictophagidae) was higher than that of C. unimaculata. In two tests, there was a relationship between length of rice cultivar duration and C. unimaculata populations with populations being highest on the short duration cultivars. On most cultivars there was no correlation between Cofana populations and percentage parasitism, nor was there a relationship between cultivar growth duration and percent parasitism. The number of the various stages of the parasite was similar in both Cofana species with the male pupal parasitic stage being most common.

“…This endoparasitoid (Plates 1 and 2) is distributed in south-east Asia, Japan, Australia, and India. 10,11 The percentage of stylopization of hoppers varies between 1 and 63% depending on the seasons. 12,13 Stylopization of C. spectra by Halictophagus spectrus Yang in Malaysia was first reported by Hirashima and Kifune 14 and Barrion and Litsinger.…”

Estimation of Fitness of Normal and Stylopized Paddy Pest, White Leafhopper Cofana spectra (Distant) (Hemiptera: Cicadellidae), in West Bengal, India through Correlation of Life History Traits

The assessment of the morphological and reproductive features of white rice leafhopper Cofana spectra (Distant) was carried out using selected characters that bear importance in determining the fitness at the individual and population levels. Morphometric measurements of the individuals reared in the laboratory as normal and stylopized with the strepsipteran parasitoid, Halictophagus australensis Perkins, were recorded and analyzed. A t-test was performed to justify whether parasitization by H. australensis affected the traits. Correlations and regression analyses were carried out to deduce the difference in relative importance of the morphological features in the life history of C. spectra and their variation because of stylopization by H. australensis. A principal component analysis (PCA) was applied on the morphometric data to further substantiate the difference observed in the traits. In case of stylopized white leafhopper (WLH), fecundity was inhibited almost completely irrespective of seasons. The effect of stylopization on the life history traits of C. spectra has been noted that supports its possible use in biocontrol.

“…The host species is also widely distributed over the same area as the parasitoid (Kathirithamby, 1992;Mazumdar and Chaudhuri, 2004). The genus Halictophagus is represented by eight species from India, of which Halictophagus australensis Perkins is distributed in the regions of Southeast Asia, Japan, Australia and India.…”

The homopteran bug Cofana spectra (Distant), also known as the white leafhopper, is abundant in rice-growing areas of India (West Bengal, Northeast and southern states) and considered as a minor pest of paddy. The proportion of Cofana spectra and the endoparasitoid Halictophagus australensis Perkins varied between months and demonstrated peak abundance during March to May and October to December, which corresponded with the rice cropping periods boro (winter crop) and aman (monsoon crop), respectively. There was a negative correlation between the influence of environmental factors (air temperature, rainfall and relative humidity) and the abundance of normal and parasitized C. spectra. The proportion of parasitization by H. australensis varied with the relative abundance of C. spectra. The effect of stylopization on C. spectra by the Strepsiptera may be one of the factors attributable to the suppression of the population levels of the paddy pest.
