Title: Prey searching behaviour of aphidophagous predator Macrolophus pygmaeus Rambur (Miridae: Hemiptera) on tomato plant
Brief Report : Prey searching behaviour M. pygmaeus by using Ephestia kuehniella eggs and Myzus persicae as prey and placing preys on different leaflets and leaflet combinations. This behaviour was also observed by placing predators on different release points, which was further correlated with leaf surface area and trichome density.When 2nd instar nymph of M. persicae was placed on the leaflet combination viz., AB, AC, BC, DC, it was found that the number of prey consumption was highest on AB (10.60) followed by AC (9.40) and BC (9.20) without differing to each other. The factor “leaf position’’ was found to have a significant effect in the prey consumption of the predator. The prey consumption was highest on the lower leaves followed by the middle and the top leaves i.e. 10.85, 10.20, 8.9, respectively. The trichome density had significant effect on prey searching behaviour of M. pygmaeus. The number of trichomes was significantly higher on the under and upper surface of apex leaves i.e. 783.75 and 409.50 from 0.5 cm2, area, respectively, in comparison to other leaves and the consumption of M. persicae was also significantly low (7.00 no.) on apex leaf. The interplay position of the prey and predator had no significant effect in the consumption of M. persicae by M. pygmaeus and the predator did not prefer any particular direction and hence the predator M. pygmaeus can be released in any part of the plant. |
