Abstract :

<p>&lt;p&gt;&amp;nbsp;In Paranemobius pictus Copulation occurs in April to August. The over active male with protruding genitalia slips under the female and inserts spermatophore in female genital capsule. During copulation both partners are in same direction and lasts up to 30 minutes (maximum) female cricket lays 85 eggs (average) in her life span of 250 days. Incubation varies as : 5-8 days (in summer), 7-12 days (in monsoon). It undergoes diapause in winter. Life cycle completes through seven instars. This cricket bear economic importance due to its pest value (on vegetable and paddy crops) and as bait in fishing&lt;/p&gt;</p>
