“…In entomological pest-host plant and natural enemies complex, studies have shown that some plants attract natural enemies of pests differentially [12,13] and the possibility of similar interactions in gastropod pest, host and natural enemies complex cannot be ruled out. These may be responsible for the variabilities in the predatory capabilities of the Drilus larvae against L. flammea in the different crops.…”

The garden snail, Limicolaria flammea is a seasonal pest of several horticultural crops in most of the agroecological areas in Nigeria. The level of damage to crops is especially enormous in the South because of its ability to feed on different crops and the timing of abundance, the early rain season, which usually coincide with onset of rain-fed crop production which expose seedlings and grown-up crop plants to serious damage. In this study, we recorded occurrence data of Limicolaria flammea in okra, carrot, sweet potato, lettuce and maize within a single multi-crop organic farm in order to understand its food preference. Activities of the predatory beetle larvae, Drilus sp was observed within the environment. The appearance of the larvae was described and its interaction with L. flammea was studied to generate some data on the proportions of snail mortality caused by Drilus sp and other mortality factors that naturally regulate the population dynamics of L. flammea within the environment. There was no statistically significant difference in the average number of snails recorded in the different cropping fields [F (4,15) =1.369, P=0.291]. The activities of Drilus larvae against L. flammea was higher in okra and carrot plots as snail mortality due to the larvae attack were significantly higher compared to what was recorded in other crop plots [F (4, 30) =3.998, P=0.01].The Drilus larvae predate on L. flammea by appertural entry, biting through the soft tissues around the mantle to gain entrance and moult into instar larvae within the snail shell in 15-20 days, leaving its exuviae behind in the shell in all the specimens observed (n=40). The Drilus species being reported in this study is morphologically distinct from other described species in available literature. The study suggested that the Drilus species is less known and there are potentials that the species could be useful in inundative biocontrol approaches for the management of pestiferous gastropod populations.

Biological control by various natural enemies, including microbial organisms, is a potential alternative to chemical control in integrated pest management (IPM) programs (Pedigo, 2002). Due to their selectivity and safety, microbial biocontrol agents are considered economical and eco-friendly components of IPM programs. These agents are often compatible with other natural enemies (Lacey & Shapiro-Ilan, 2008). The most important group of microbial agents are entomopathogenic fungi (EPF) (Liu et al., 2017). Approximately 60% of insect pathogens are EPF (Liu et al., 2017). The mycelia of EPF can penetrate the insect integument directly, whereas other entomopathogens, including bacteria, viruses, and protozoa, need to be ingested to infect insects (Lovett & Leger, 2017). Thus, EPF can play an important role in controlling sap-feeding insects, such as hemipterans, in microbiological control programs (Broumandnia et al., 2021). Aphids are important sap-feeding pests in many crops (Blackman & Eastop, 2008). They can cause severe damage

“…The central hole was connected to the suction pump, air was passed through the central hole at the rate of 4 KPa/min. A 12‐Watt LED bulb as a light source was hung at the centre of the olfactometer (12 inches) (Rashedi et al, 2019). Apparatus was surrounded with a black cloth to keep uniform conditions throughout the experiment.…”

1. Diaphorina citri is a major pest of citrus tress because it is the vector of citrus greening. Growers rely on insecticides to manage D. citri, but these have side effects (e.g., pollution, public health issues, pest resistance, etc.). There is a need to assess the role of semiochemicals in the biological control of D. citri. A four-armed olfactometer was used to evaluate the orientation response of larvalChrysoperla carnea, a natural enemy, to odours produced by young leaves, mature leaves, ripe fruit and fruit peel of mandarine orange (Citrus reticulata). Lacewing responses to both uninfested plant parts and infested with D. citri were measured.3. Results showed that C. carnea discriminated between the volatiles emitted by plant parts and citrus psyllid. In all tested combinations (I-V), both in the absence and presence of citrus psyllid, all first, second and three C. carnea preferred the volatiles of fresh leaves and old leaves over other plant parts. Moreover, all three instars of the predator significantly preferred the area having volatile of citrus psyllid.4. Volatiles of fresh leaves and old leaves can be used in the management of citrus psyllid. Moreover, this tritrophic interaction could play a vital role in developing IPM strategies for the management of citrus psylla.
