Effect of host-generated cues on foraging speed of herbivore as well as its natural enemies was studied under net house conditions in Meghalaya, India. Foraging speed of <em>P. brassicae</em> was significantly higher towards the healthy plants, whereas it was lowest towards the damaged plants along with herbivore cues. In contrast foraging speed of parasitoids <em>H. ebeninus </em>and<em> C. glomerata</em> was highest towards damaged plants along with herbivore cues and lowest towards healthy plants. It indicates that herbivore and its parasitoids respond to the volatiles generated by their host. In addition to host plants natural enemies also utilize herbivore-generated cues for their detection.

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

Abstract Tuta absoluta (Meyrick) has become a serious menace to sustainable production of tomato in Kenya. A survey was conducted between April 2015 and June 2016 to determine its distribution, abundance, infestation, and damage levels on tomato, and associated natural enemies. Trap counts of T. absoluta moths were recorded in all surveyed 29 counties, which indicated its nationwide distribution irrespective of altitude. Tuta absoluta was present in both open fields and greenhouses. The highest moth/trap/day was 115.38 ± 15.90. Highest leaf infestation was 92.22% and the highest number of mines and larvae per leaf were 3.71 ± 0.28 and 2.16 ± 0.45, respectively. Trap captures in terms of moth/trap/day were linearly and positively related to leaf infestations in open fields (R2 = 0.81) and greenhouses (R2 = 0.61). Highest fruits’ infestation and damage were 60.00 and 59.61%, respectively, while the highest number of mines per fruit was 7.50 ± 0.50. Nesidiocoris tenuis (Reuter) and Macrolophus pygmaeus (Rambur) were identified as predators of T. absoluta larvae. Nine species of larval parasitoids were recovered from infested foliage, with a combined parasitism of 7.26 ± 0.65%. Hockeria species was the most dominant (31.25%) and accounted for 12.88 ± 1.47% parasitism. Two species of larval parasitoids, Hockeria and Necremnus were obtained from sentinel plants with an average parasitism of 1.13 ± 0.25. The overall abundance and parasitism rates of recovered natural enemies were low to effectively control the field populations of T. absoluta. These findings form the basis of researching and developing effective and sustainable management strategies for the pest.

<p class="5abstrak"><em>Papilio</em><em> blumei</em> is an endemic butterfly of Sulawesi and especially in Bantimurung Bulusaraung National Park. This research was to observed of the behaviour and natural enemies of <em>P. blumei</em> in Bantimurung Bulusaraung National Park. The behaviour of the insect were mating, foraging, competiting, ovipositing and mud-puddling. Life table was used for analysis of mortality factors, therefore the number of mortality was analyzed by key-factors formulation. The result indicated that mating strategies is patrolling. Foraging activity of the sixth instar was the highest compared to the other instars and the lowest one activity of the prapupa stadium of <em>P. blumei</em>. Nectar host plants for the imago of butterfly were <em>Sarcosephalum latifolius</em> and <em>Eugenia sp</em>. There was <em>Scudderia sp</em>. as an interspesific competitor for larval <em>P. blumei</em>. The intraspesific competitor of the imago stage was male of <em>P. blumei</em>. Female <em>P. blumei</em> laid eggs on abaxial leaf <em>E.hupehensis</em> and the eggs hatched after six days. The larva of  <em>P. blumei</em> has a overheating behaviour and the adults has a mud puddling. The natural enemies of <em>P.blumei </em>is <em>Trichogramma</em> sp., with k value = 0.381, <em>Pteromalus </em>sp., with k value = 0.125 and <em>Formica </em>sp., with k value = 0.096.</p>

Preliminary Study

The cottony-cushion scale, Icerya purchasii Maskell, is one of the soft scales that attack a large variety of plants and trees in our Island. A series of host plants are listed and the insect is briefly described. Its distribution and natural enemies are also listed. Two insecticides, namely Parathion and Malathion, were tested for the control of the cottony-cushion scale in Australian pine, Casuarina equisetifolia Forst. Total control was obtained for all adult scales and crawlers with both insecticides, while in the checks both stages continued alive. It was found that the insecticides were not effective in the control of the eggs.

First Time

Life stages of Henosepilachna implicata (Mulsant), an economically important species of Epilachnini in India, are documented and illustrated. Mitochondrial DNA sequence data is provided for the first time for H. implicata with additional details on its host plants, distribution, and natural enemies. Its similarities and differences with other common pestiferous Henosepilachna spp. in India such as H. vigintioctopunctata (F.), H. septima (Dieke) and H. pusillanima (Mulsant) are discussed. Epilachna circularis Korschefsky, 1933 is found to be conspecific with H. implicata and is reduced to a junior synonym of the latter (new synonym). Notes are given on the distribution and natural enemies of some other species of Epilachnini of the Indian region.
