Studies on new invasive pest Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) and its natural enemies
The natural enemy complex of S. frugiperda for the first time from India, commonly known as fall armyworm, is reported along with associated natural enemies and studies to manage this pest by any/all means are in progress. Expand
The New Invasive Pest Tuta absoluta (Meyrick) (lepidoptera: Gelechiidae) in India and its Natural Enemies along with Evaluation of Trichogrammatids for its Biological Control
Toba-adapted strains of Trichogramma were evaluated and it was found that these strains could parasitise T. absoluta eggs and the parasitism rates were 5.0%, 51.1% and 68.2% respectively. Expand
Predatory Potential of Two Indigenous Anthocorid Predators on Phenacoccus solenopsis Tinsley and Paracoccus Marginatus Williams and Granara De Willink
Though B. pallescens could predate on both mealybug species, A. muraleedharani appeared to be a more voracious predator of P. solenopsis based on its greater predatory potential, higher adult longevity and shorter nymphal duration. Expand
The Effectiveness of Trichogramma chilonis, Trichogramma pretiosum and Trichogramma brasiliense (Hymenoptera: Trichogrammatidae) as Parasitoids of Helicoverpa armigera (Lepidoptera: Noctuidae) on…
The performance of three species of trichogrammatids on the pest, Helicoverpa armigera, was evaluated in the laboratory and screenhouse conditions in Karnataka, India during 1996-97 and indicated that Trichogramma chilonis was the most effective parasitoid of H. armigersa. Expand
Host Plant-Mediated Orientational and Ovipositional Behavior of Three Species of Chrysopids (Neuroptera: Chrysopidae)
Investigations on the host plant-mediated orientational and ovipositional behavior of three species of adult chrysopids, namely Chrysoperla carnea, Mallada boninensis, and Mallada astur, toward three different host plants indicated that C. carnea males had a significantly higher preference for sunflower and females for bothSunflower and cotton, while pigeonpea was least preferred.

Cold tolerance of coccons ofAllorhogas pyralophagus [Hym.: Braconidae]
Cold tolerance studies were conducted under laboratory conditions for coccons of Allorhogas pyralophagus Marsh, a Mexican parasitoid of graminaceous borers, and it is clear that cocoons are more amenable to short-term storage. Expand
Potential natural enemies of the invasive rugose spiraling whitefly, Aleurodicus rugioperculatus Martin in India
This communication is the first report of the rugose spiraling whitefly, its host plant range and associated natural enemies in India. Expand
Evaluation of an anthocorid predator, Blaptostethus pallescens against two-spotted spider mite, Tetranychus urticae.
In the net house studies, there was a 78% reduction in the mite population in the treated bhendi plants where the anthocorid releases were made, in comparison to control indicating that B. pallescens is a promising candidate to control two spotted spider mites. Expand
Efficacy of botanicals with Nomuraea rileyi (Farlow) Samson in groundnut ecosystem.
The effect of parasitism byHyposoter didymator [Hym.: Ichneumonidae] on food consumption and utilization bySpodoptera litura [Lep.: Noctuidae]
There seems to be a definite immediate advantage to the crop on releasing the parasitoid due to the reduced consumption of food, and efficiency of conversion of ingested and digested food into body weight was greater in unparasitized larvae after the 2nd day of parasitization. Expand
