“…The present study clearly shows that R. longifrons hide under different objects and, the preference for an object is function of the time of the day. The reduviid predator Rhynocoris fuscipes (Fabricius) also showed similar hiding behavior 31 . This hiding behavior is an advantageous in the framework of an IPM because it allows this predator to better surprise the prey it captures.…”

“…This hiding behavior is an advantageous in the framework of an IPM because it allows this predator to better surprise the prey it captures. Moreover, it allows a better escaping from their natural enemies such spiders and wasps [31][32][33] . Therefore, we can conclude that R. longifrons nymphs and adults can survive and adapt in the cotton agro-ecosystem after its release.…”

“…Hiding behaviour of the predator inside the screen houses. To record the hiding places of the predator when it was released in cotton during an augmentative pest management programme, the methodology described by Tomson et al 31 was used. Observations of hiding behaviour of R. longifrons were carried out in a screen house (12 m length × 7.8 m width) using 30 day-old cotton plants (variety: MCU-5).…”

“…Biocontrol potential of R. longifrons in relation to day and night hours. Modified methodology of Tomson et al 31 was followed for bioefficacy experiments. For the experiments, cotton seeds of MCU-5 variety were sown in cement pots (36 × 30 × 22 cm) and maintained in screen house at St. Xavier's College, Palayamkottai.…”

Rhynocoris longifrons (Hemiptera: Reduviidae) is a generalist predator of many cotton insect pests. The hiding behaviour of this predator, which is one of the key factors of predation success, was investigated under screen house conditions. Moreover, we evaluated its biocontrol potential against Aphis gossypii (Hemiptera: Aphididae), Dysdercus cingulatus (Hemiptera: Pyrrhocoridae), Phenacoccus solenopsis (Hemiptera: Pseudococcidae), and Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) under screen house and field conditions. Results showed that R. longifrons life stages preferred to hide under small pebbles in the screen house tests. All the R. longifrons life stages showed a biocontrol potential against the four insect pests under screen house conditions. However, their biocontrol potential had not varied in relation to day and night hours. Augmentative releases of R. longifrons were carried out for two seasons such as Southwest monsoon, 2011 and post-monsoon, 2012. The augmentative release of R. longifrons reduced significantly insect pests on cotton. In fact, the release of this predator in cotton fields was capable to reduce the population of H. armigera (50%), P. solenopsis (28%), D. cingulatus (18.8%), and A. gossypii (11.8%) during the rain fed condition (south-west monsoon season). During irrigated condition (post-monsoon season), populations of D. cingulatus were reduced by 26%, than P. solenopsis (20.6%), and A. gossypii (16.8%). Except ants, no negative impact was reported on other natural enemies present in the cotton field. Significantly higher crop yield and cost benefit ratio was observed in the predator release plots indicating that R. longifrons can be used in an integrated pest management program for multiple cotton pests. Cotton (Gossypium hirsutum L., Malvaceae), is an important cash crop throughout the world. However, its production is severely hampered by several abiotic and biotic factors, such as insect attacks that lead to significant yield reduction. Aphis gossypii Glover (Hemiptera: Aphididae) 1 , Dysdercus cingulatus (Fab.) (Hemiptera: Pyrrhocoridae) 2 , Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) 3 , and Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) 4 are considered as economically important pests of cotton. Conventional synthetic chemical insecticides are typically extensively used causing significant side effects including pesticide resistance 5 as well as having many ecological and biological impacts 6. Members of Reduviidae are abundant predators of many economically important insect pests 7-9. Reduviids are common in cotton agro-ecosystems 10,11. However, they often fail to colonize fields to provide effective control of the pests. In such a situation, augmentative biological control can be an important approach to protect the cotton. Augmentative biological control is practiced worldwide with more than 150 species of natural enemies now commercially available 12. However, generalist predators, particularly predatory bugs, have been largely ignored for a...

The cotton mealybug Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae), is a highly invasive and harmful pest. It causes considerable loss of cotton crops in China, India and Pakistan. Little is known about its bionomics since it was first recorded in Pakistan and India in 2005. Rapid spread of this pest worldwide has accelerated research on its biology, ecology and management. The P. solenopsis has a short life cycle, and optimal temperatures lead to an increase in the number of generations per year, which is a serious threat to cotton crop production. Cotton mealybug is native to the USA, although it has now spread to >43 countries. Insecticidal control is the primary and dominant practice for this pest, and its resistance to commonly used insecticides is increasing. Biocontrol agents have strong potential for the management of nymphal instar stages. We read >250 articles related to our review title and finally reviewed recent advances in the understanding of P. solenopsis biology, ecology and control approaches, aiming to highlight integrated and biological management practices of this pest.
