The genus Eocanthecona is distributed in oriental, Ethiopian and Australasian regions.  This genus is represented by 24 species from the world of which only five species are reported from India.  The bug Eocanthecona concinna was first reported from Hong Kong, China in 1867.  Later again reported from different regions of China and Taiwan in 1910, 1934, 1961 and 2013.  The review of literature indicates no record of E. concinna in India.  Hence, the report of this stinkbug from Kolhapur becomes first report for India and the geographic range of the species in China and Taiwan is extended towards India.

The aim of this work was to test if egg viability of polyandrous females was increased with increasing number of matings. Longevity and reproductive output of females of the predatory stinkbug Podisus nigrispinus that were allowed to mate for 0, 1, 2, 3 times or were in the continuous presence of the same male was evaluated. Polyandry resulted in diminished sperm depletion. Females that had mated three times or that were in continuous presence of a male produced more offspring than females that mated once or twice throughout their lifetime. There was a negative correlation of mating history on female longevity. Results indicated that remating, either with same male or with different males were crucial for maximization of the reproductive success of females.

Podisus nigrispinus (Dallas) (Heteroptera: Pentatomidae) is an important biological control agent of the cotton leafworm [Alabama argillacea (Hübner)] in the cotton crops in Brazil. The use of selective products such as pyrethroids has been emphasized in this agroecosystem. Then, the susceptibility of the predatory stinkbug P. nigrispinus to the pyrethroid insecticide gamma-cyhalothrin was studied in the laboratory. Nymphs and adults of the predator were exposed to seven concentrations of the gamma-cyhalothrin via topical contact and ingestion through treated water. The concentrations studied of this insecticide via topical application were relatively harmless for adults of P. nigrispinus (females: LC50 = 143.5 ppm a.i., and males: LC50 = 145.1 ppm a.i.) and 5th-instar nymphs (LC50 = 103.9 ppm) as compared to via ingestion (females: LC50 = 1.98 ppm a.i., males: LC50 = 1.91 ppm a.i., and 5th-instar nymphs: LC50 = 2.05 ppm a.i.). The use of pyrethroids and beneficial insects in IPM programs should be better evaluated.
